Abstract

Background

Research has consistently shown that some children are more vulnerable at the time of school readiness. Better understanding the characteristics of these children is therefore important. Most studies have used a variable-based approach, which may mask the presence of small but important subgroups of children with mixed patterns of readiness strengths and weaknesses. Identifying subgroups with mixed readiness patterns using a person-centered approach matters because their developmental trajectories might differ in important ways from children with broader difficulties across all readiness domains.

Objective

This systematic review attempts to synthesize existing profiles of school readiness conducted on preschool-aged children and to describe how these various profiles are associated with children’s academic achievement and social adjustment during their school years. Specifically, we described how the school readiness profiles vary in number of profiles identified and differences in the specific domains of school readiness. We further describe the school readiness profiles and how they predict later academic and social outcomes. Furthermore, we focus on profile differences between at-risk and non-at-risk preschoolers.

Methods

Longitudinal studies published between 2005 and 2022 on profiles of school readiness before school entry and at least one subsequent academic and/or social outcomes were extracted from five databases. Eight articles were included in this systematic review out of the 117 screened peer-reviewed articles.

Results

All the studies incorporated both the cognitive and socioemotional domains of school readiness in their profiles. Fifteen profiles of school readiness at preschool age were identified based on the child level of cognitive and socioemotional skills, with 7 profiles at risk of later academic and social difficulties. Despite variation, children in these at-risk profiles of school readiness shared similar features.

Conclusion

This literature review provides an exhaustive summary on the number of profiles and domains of school readiness most frequently reported in studies using a person-centered approach. Yielding an in-depth description of at-risk profiles of school readiness can help designing early preventive intervention for these children.

Child school readiness, defined as their ability to function successfully in the school context, is one key early-life factor enabling well-being, successful psychosocial and school adjustment across the life course (Pan et al., 2023Pan, X.

This systematic review aims to describe existing profiles of preschoolers’ school readiness and how they associated with subsequent children’s academic and social outcomes, with a particular focus on school readiness profiles most at risk of persistent difficulties.

What skills make up school readiness?

As a conceptual framework, school readiness has been defined as a holistic and multidimensional concept involving several developmental domains such as cognitive, language, socioemotional, and motor/physical skills (Boivin & Bierman, 2014Boivin, M., & Bierman, K..L. (2014). Promoting school readiness and early learning: Implications of developmental research for practice (M. Boivin & K. L. Bierman, Eds.; 2014-00192-000). The Guilford Press. ; Forget-Dubois et al., 2007Forget-Dubois, N., Lemelin, J.-P., Boivin, M., Dionne, G., Séguin, J. R., Vitaro, F., & Tremblay, R. E. (2007).

https://doi.org/10.1207/s15566935eed1701... ). The cognitive domain refers to ways of thinking and acquiring knowledge that promotes learning. The language domain includes literacy skills that promote effective communication with others. Competence in the cognitive and language domains usually encompasses memory and attentional skills, expressive and receptive vocabulary, and the early numeracy and reading skills, such as knowing numbers and letters (Duncan et al., 2007Duncan, G. J., Dowsett, C. J., Claessens, A., Magnuson, K., Huston, A. C., Klebanov, P., Pagani, L. S., Feinstein, L., Engel, M., Brooks-Gunn, J., Sexton, H., Duckworth, K., & Japel, C. (2007).

Snow (Eds.), School readiness and the transition to kindergarten in the era of accountability (pp. 197-216). Paul H Brookes Publishing. 2007-03648-010.). The socioemotional domain refers to the development of key social behaviors that help build and maintain positive relationships with others (Sabol & Pianta, 2012Sabol, T. J., & Pianta, R. C. (2012). Patterns of school readiness forecast achievement and socioemotional development at the end of elementary school. Child Development, 83(1), 282-299. https://doi.org/10.1111/j.1467-8624.2011.01678.x
https://doi.org/10.1111/j.1467-8624.2011... ). It usually includes low levels of externalizing (e.g., aggression, opposition) and internalizing (e.g., anxiety, depression) behaviors (Duncan et al., 2007Duncan, G. J., Dowsett, C. J., Claessens, A., Magnuson, K., Huston, A. C., Klebanov, P., Pagani, L. S., Feinstein, L., Engel, M., Brooks-Gunn, J., Sexton, H., Duckworth, K., & Japel, C. (2007).

https://doi.org/10.1207/s15566935eed1701... ). The motor/physical domain refers to children’s health and motor development that support engagement and learning in their environments (Cinar et al., 2023Cinar, E., Fitzpatrick, C., Almeida, M. L., Camden, C., & Garon-Carrier, G. (2023). Motor skills are more strongly associated to academic performance for girls than boys.

https://doi.org/10.1037/a0018881... ). This domain generally involves physical fitness, fine and gross motor skills, and health status.

Although interrelated, each domain is a unique aspect of school readiness. It is now well documented that these domains of school readiness prior school entry are differently associated with later academic achievement and performance at standardized tests (Claessens et al., 2009Claessens, A., Duncan, G. J., & Engel, M. (2009). Kindergarten skills and fifthgrade achievement: Evidence from the ECLS-K. Economics of Education Review, 28(4), 415-427. https://doi.org/10.1016/j.econedurev.2008.09.003

Children at risk of low school readiness

Children may experience school readiness difficulties, especially during the transition into formal schooling. Teacher reports that 48% of children manifest difficulty adjusting to school during the transition to kindergarten (Rimm-Kaufman et al., 2000Rimm-Kaufman, S. E., & Pianta, R. C. (2000). An ecological perspective on the transition to kindergarten: A theoretical framework to guide empirical research. Journal of Applied Developmental Psychology, 21(5), 491-511. https://doi.org/10.1016/S0193-3973(00)00051-4
https://doi.org/10.1016/S0193-3973(00)00... ), with most frequently reported problems being difficulty following directions or working independently, and a lack of pre-academic skills. For most children, these school readiness difficulties progressively fade away as adaptation unfolds during the elementary school years (Parent et al., 2019Parent, S., Lupien, S., Herba, C. M., Dupéré, V., Gunnar, M. R., & Seguin, J. R. (2019). Children’s cortisol response to the transition from preschool to formal schooling: A review. Psychoneuroendocrinology, 99, 196-205.; Pingault et al., 2015Pingault, J. B., Tremblay, R. E., Vitaro, F., Japel, C., Boivin, M., & Côté, S. M. (2015).

https://doi.org/10.1016/S0193-3973(00)00... ), but some will still experience serious adaptative problems (Simard et al., 2018Simard, M., Lavoie, A., Audet, N., Tremblay, M. -È., & Bellefeuille, A. (2018). Enquête québécoise sur le développement des enfants à la maternelle 2017: Portrait statistique pour le Québec et ses régions administratives.

https://doi.org/10.1016/S0193-3973(00)00... ).

In particular, children with expressive or receptive language difficulties, those lagging behind in terms of general knowledge, and children with disruptive behaviors are at higher risk of low school readiness (Abenavoli et al., 2017Abenavoli, R. M., Greenberg, M. T., & Bierman, K. L. (2017). Identification and validation of school readiness profiles among high-risk kindergartners.

https://doi.org/10.1007/s00431-011-1605-... ). Evidence also suggests that children from minority language (Janus et al., 2010Janus, M., Hughes, D., & Duku, E..K. (2010). Patterns of school readiness among selected subgroups of Canadian children: Children with special needs and children with diverse language backgrounds.

Profiles of school readiness

Most studies to date have used a variable-oriented approach which assumes that while individuals differ quantitatively across variables, they are qualitatively alike in the nature of the relationships between variables. As such, a variable-oriented approach may mask the presence of small but important subgroups of children with mixed patterns of school readiness strengths and weaknesses. Identifying subgroups with mixed readiness patterns matters because their developmental trajectories might differ in important ways from children with broader difficulties across all school readiness domains. One way to examine the interplay among school readiness domains is to use a person-centered approach. A person-centered approach confers several advantages over a variable-centered approach (Laursen & Hoff, 2006Laursen, B., & Hoff, E. (2006). Person-centered and variable-centered approaches to longitudinal data. Merrill-Palmer Quarterly, 52(3), 377-389. https://doi.org/10.1353/mpq.2006.0029
https://doi.org/10.1353/mpq.2006.0029... ). This approach allows us to better capture population heterogeneity by identifying subgroups of children that could go undetected in variable/mean-based approaches. Specifically, it allows for the possibility that subgroups of children show distinct trends, thus providing a more nuanced view of children’s level (and development) of school readiness. From a preventive perspective, using a person-centered approach to establish profiles of school readiness among preschoolers may help in identifying children most at-risk of persistent academic and/ or social difficulties (Weller et al., 2020Weller, B. E., Bowen, N. K., & Faubert, S. J. (2020). Latent class analysis: A guide to best practice. Journal of Black Psychology, 46(4), 287-311. https://doi.org/10.1177/0095798420930932
https://doi.org/10.1177/0095798420930932... ). Furthermore, not only is it essential to document the various profiles of school readiness, but it is also crucial to estimate whether and how some of these profiles foresee later academic and social difficulties (Abenavoli et al., 2017Abenavoli, R. M., Greenberg, M. T., & Bierman, K. L. (2017). Identification and validation of school readiness profiles among high-risk kindergartners. Early Childhood Research Quarterly, 38, 33-43. https://doi.org/10.1016/j.ecresq.2016.09.001
https://doi.org/10.1016/j.ecresq.2016.09... ).

From a theoretical perspective, a person-centered approach simultaneously considers the multiple cognitive, language, socioemotional, and physical/motor characteristics of the child, which align with the core definition of school readiness as a multidimensional concept (Bergman & Magnusson, 1997Bergman, L. R., & Magnusson, D. (1997). A person-oriented approach in research on developmental psychopathology. Development and Psychopathology, 9(2), 291-319. https://doi.org/10.1017/S095457949700206X
https://doi.org/10.1017/S095457949700206... ; Bergman & Trost, 2006Bergman, L. R., & Trost, K. (2006). The person-oriented versus the variable- oriented approach: Are they complementary, opposites, or exploring different worlds?

Snow (Eds.), School readiness and the transition to kindergarten in the era of accountability (pp. 197-216). Paul H Brookes Publishing. 2007-03648-010.). From a statistical point of view, this approach does not make strong assumptions about the population distribution of the putative profiles. It also considers individual differences to determine the optimal number of potential profiles by clustering within the same profile preschoolers with similar school readiness attributes (Sandilos et al., 2019Sandilos, L. E., Whittaker, J. V., Vitiello, V. E., & Kinzie, M. B. (2019). Preschoolers’ school readiness profiles and the teacher-child relationship: A latent transition approach. Journal of Applied Developmental Psychology, 62, 185-198. https://doi.org/10.1016/j.appdev.2019.02.010
https://doi.org/10.1016/j.appdev.2019.02... ).

Using a multidimensional conceptual framework of school readiness, the present article provides a systematic review of studies that have used a person-centered approach to describe profiles of school readiness among preschoolers and their associated later academic and social outcomes. Existing studies on this topic differ from one another on the basis of the dimensions of school readiness being studied and methodological approaches (Gobeil-Bourdeau et al., 2022Gobeil-Bourdeau, J., Lemelin, J.-P., Letarte, M.-J., & Laurent, A. (2022). Can temperament predict school readiness in at-risk kindergarteners? A combination of variable-oriented and person-oriented approaches. Early Education and Development, 33(7), 1117-1136. https://doi.org/10.1080/10409289.2021.1947633
https://doi.org/10.1080/10409289.2021.19... ). For this reason, systematic reviews are important for identifying areas of consensus as well as existing gaps. Specifically, we aim to describe how the profiles identified in the literature vary in the number of profiles identified and differences in the specific dimensions of school readiness. It is expected that each study included in this systematic review will report at least three profiles of school readiness, with a small but significant group of children with a low school readiness profile (Garon-Carrier et al., 2018Garon-Carrier, G., Boivin, M., Lemelin, J. P., Kovas, Y., Parent, S., Séguin, J. R., Vitaro, F., Tremblay, R. E., & Dionne, G. (2018). Early developmental trajectories of number knowledge and math achievement from 4 to 10 years: Low-persistent profile and early-life predictors. Journal of School Psychology, 68, 84-98. https://doi.org/10.1016/j.jsp.2018.02.004
https://doi.org/10.1016/j.jsp.2018.02.00... ; Simard et al., 2018Simard, M., Lavoie, A., Audet, N., Tremblay, M. -È., & Bellefeuille, A. (2018). Enquête québécoise sur le développement des enfants à la maternelle 2017: Portrait statistique pour le Québec et ses régions administratives. Institut de la statistique du Québec.). We also qualitatively describe the school readiness profiles and how they predict academic and social outcomes during compulsory education. Furthermore, we focus on profile differences between at-risk and non-at-risk preschoolers. We expected children from linguistically and ethnically diverse families, those with low parental education and socioeconomic status, and a greater proportion of boys than girls to fall on a low/at-risk profile of school readiness.

Methods

This systematic review follows the propositions for systematic reviews from the University of York (Centre for Reviews and Dissemination, 2009Centre for Reviews and Dissemination. (2009). Core principles and methods for conducting a systematic review of health interventions. In CRD’s guidance for undertaking reviews in healthcare (3rd ed.). United Kingdom: York Publ. Services.). Systematic reviews adopt a sequential step-by-step rigorous scientific approach to identify and synthesize evidence on a specific research question.

Step 1: Clarifying the research question

The review aims to describe the various school readiness profiles of preschoolers (i.e., before school entry or prior to age 6) and their associated academic and social outcomes in grade 1 (age 6) or upward. The profiles were obtained with a person-centered statistical approach such as a latent class/profile analysis or a cluster analysis.

Step 2: Identifying relevant studies

An electronic search was conducted in PsycINFO, ERIC, Academic Search Complete, Education Source, and ProQuest in May 2022. Our search strategies included keywords on school readiness ("school readiness" OR "preschool skills" OR "kindergarten readiness" OR "preschool competenc*"), followed by keywords about the person-centered approach or the type of analysis ("person-centered" OR "person-oriented" OR cluster OR "latent class" or "pattern-based" OR "latent profile"). No keyword about the social and academic outcomes was introduced, as this has been proved too restrictive. However, the studies that we selected (see step 3) included academic achievement and/or social adjustment outcomes. A number of 167 studies came out from this research. Only peer-reviewed articles (n = 117) were selected to ensure a minimum of methodological quality.

Step 3: Selecting relevant studies

Studies had to meet the following criteria: (1) the school readiness profiles had to be the independent variable; (2) in accordance with the multidimensional conceptual definition of school readiness, the profiles had to include at least two domains of school readiness; (3) the profiles had to be conducted before the beginning of the elementary school years; and (4) studies had to examine academic achievement and/or social adjustment from the elementary school years (or upward) as a dependent variable. Studies examining the effectiveness of an intervention program, and studies conducted on children with specific disorders (e.g., autism spectrum disorder, disabilities, traumatic brain injury), were excluded. Only 12 studies were selected based on these criteria. Among the selected studies, two were written by the same authors. These two articles reported school readiness profiles that were conducted on the same sample (sociodemographic similarities). They revealed identical school readiness profiles and had similar associations with later academic achievement. Given the great similarities between these two studies, we kept only one of the two articles, i.e., the one providing the most detailed methodology (Quirk et al., 2013Quirk, M., Nylund-Gibson, K., & Furlong, M. (2013). Exploring patterns of Latino/a children’s school readiness at kindergarten entry and their relations with grade 2 achievement. Early Childhood Research Quarterly, 28(2), 437-449. https://doi.org/10.1016/j.ecresq.2012.11.002
https://doi.org/10.1016/j.ecresq.2012.11... ). Three studies out of 11 were also excluded (Goble et al., 2019Goble, P., Pianta, R. C., & Sabol, T. J. (2019). Forecasting youth adjustment at age 15 from school readiness profiles at 54 months. Applied Developmental Science, 23(4), 353-370. https://doi.org/10.1080/10888691.2018.1436439
https://doi.org/10.1080/10888691.2018.14... ; Quirk et al., 2016Quirk, M., Grimm, R., Furlong, M. J., Nylund-Gibson, K., & Swami, S. (2016). The association of Latino children’s kindergarten school readiness profiles with grade 2-5 literacy achievement trajectories. Journal of Educational Psychology, 108(6), 814-829. https://doi.org/10.1037/edu0000087
https://doi.org/10.1037/edu0000087... ; Sabol & Pianta, 2012Sabol, T. J., & Pianta, R. C. (2012). Patterns of school readiness forecast achievement and socioemotional development at the end of elementary school. Child Development, 83(1), 282-299. https://doi.org/10.1111/j.1467-8624.2011.01678.x
https://doi.org/10.1111/j.1467-8624.2011... ) because they reported the same profiles of school readiness that were previously published to examine how these profiles related to different academic or social outcomes. This led to a total of eight selected studies.

Step 4: Assessing quality of studies

We assessed the quality of the selected studies (n = 8) according to their methodological features. Studies needed to include a clear description of the following: (1) sample characteristics (e.g., sex, age, ethnic group, socioeconomic status), (2) indicators of school readiness incorporated in each profiles (e.g., instruments being used), (3) statistical analysis conducted to create the profiles, and (4) measures of academic and/or social outcomes and of the analysis performed to associate the profiles of school readiness with the outcomes. The quality of the selected studies was satisfying and was judge deemed adequate to be included in this systematic review.

Step 5: Extracting data

We extracted the methodological characteristics of each study. We also highlighted some characteristics of the school readiness profiles identified in each study, such as the number of profiles, the proportion of children in each profile, and their level on each indicator of school readiness. To examine how the school readiness profiles were differentially associated with later academic and/or social outcomes, we extracted the information about the strength and the direction (positive or negative) of these associations.

Results

Methodological characteristics of the studies

Table 1 shows the methodological characteristics of the studies (n = 8). Most studies reported school readiness profiles conducted on a normative sample (n = 5; 62.5%). Three studies created school readiness profiles on at-risk samples (n = 3; 37.5%) including either children with language difficulties or from a family with a low socioeconomic status. All studies had a sample with a similar proportion of boys and girls. Between one and seven socioemotional indicators of school readiness were used to create profiles, such as internalizing and externalizing problems (5 out of 8 studies) and social competence (n = 4). Most of these indicators were reported by the teacher and the parents. Only one study measured socioemotional indicators of school readiness with direct observation (n = 1). Cognitive indicators of school readiness were measured with standardized tests taken by the child (n = 6) or reports by the teachers (n = 5). Early academic skills, such as knowing numbers, letters, and colors, were reported in six studies, and five studies measured language skills, such as receptive vocabulary, expressive language, and communication skills. Other cognitive indicators of school readiness were also measured in five studies, such as executive functions, problem-solving skills, general knowledge, and IQ.

In addition, four studies included the level of children motor/physical skills in their school readiness profiles. One study, unlike others, also conducted school readiness profiles using parental attributes (e.g., parent psychological distress, parenting efficacity) and community characteristics (e.g., neighborhood social capital, quality of school environment).

Summary of the school readiness profiles

Differences in the specific dimensions of school readiness

Among the eight selected studies, only half of them included all the domains of school readiness, i.e., the language, cognitive, socioemotional, and motor/physical skills (Christensen et al., 2020Christensen, D., Taylor, C. L., Hancock, K. J., & Zubrick, S. R. (2020). School readiness is more than the child: A latent class analysis of child, family, school and community aspects of school readiness.

https://doi.org/10.1080/10888691.2020.17... ). One study incorporated three domains of school readiness out of four (language, cognitive, socioemotional) in their profiles (Fitzpatrick, 2017Fitzpatrick, C. (2017). Ready for kindergarten: Are intelligence skills enough?South African Journal of Childhood Education,7(1), 512.https://doi.org/10.4102/sajce.v7i1.512
https://doi.org/10.4102/sajce.v7i1.512... ). Three studies conducted profiles with only two domains of school readiness, the cognitive and socioemotional domains (Konold & Pianta, 2005Konold, T. R., & Pianta, R. C. (2005). Empirically-derived, person-oriented patterns of school readiness in typically-developing children: Description and prediction to first-grade achievement.

https://doi.org/10.1207/s1532480xads0904... ; McWayne et al., 2012aMcWayne, C. M., Cheung, K., Green Wright, L. E., & Hahs-Vaughn, D. L. (2012a). Patterns of school readiness among Head Start children: Meaningful within- group variability during the transition to kindergarten.

https://doi.org/10.1016/j.ecresq.2011.10... ).

All the studies, however, incorporated both the cognitive and socioemotional domains of school readiness in their profiles, suggesting these two domains as core components of school readiness. For this reason, we next described all the existing profiles from the selected studies based on these two domains of school readiness.

The number of profiles

Each study reported between 3 and 6 profiles of school readiness. These profiles varied based on the level (high, average, or low) on each domain of school readiness (see ^{Table S1, in supplementary material} Additional file 1. Supplementary table: Table S1. Detailed description of the profiles of school readiness ). Overall, 15 profiles were identified across studies based on the cognitive and socioemotional domains of school readiness. These profiles are shown in Table 2.

Profiles of school readiness based on the level of cognitive and socioemotional skills

Description of school readiness profiles

As shown in Table 2, each profile was characterized by either a high, an average, or a low level on the cognitive and socioemotional domains of school readiness. Profiles of children could also be heterogeneous, which means they had various levels within the cognitive or within the socioemotional aspect of school readiness, depending on the indicators being used. Three profiles of school readiness were qualified as balanced since they grouped children with similar levels of cognitive and socioemo- tional skills (on the diagonal in Table 2). These profiles were the most frequently reported ones (77.7% of studies found at least one balanced profile). For instance, the high-balanced profile (B +) includes children with high levels of cognitive and socioemotional skills. This profile is highly prevalent among studies and has a greater proportion of girls than boys. Four studies also identified a moderate-balanced profile (M) of children with an average level of both cognitive and socioemotional skills. The Low-Balanced profile (B-) includes children with low cognitive and low socioemotional skills. This profile of preschoolers shows the lowest levels of school readiness. It includes between 7 and 31% of children across studies (n = 5 out of 8 studies), and as expected, it has a greater proportion of boys than girls. One study had two Low-Balanced profiles that were different based on children’s levels of motor/physical skills (low vs average).

Table 2 also shows six unbalanced profiles of school readiness, with different levels of cognitive vs socioemotional skills. Out of them, two profiles were high on one aspect but low on the other. In other words, one profile had high level of socioemotional skills but low level of cognitive abilities (SE + C-), and one profile had high cognitive abilities but low socioemotional skills (C + SE-). Four profiles had an average level on one domain (cognitive or socioemotional) of school readiness and were high (C + SE; SE + C) or low (C-SE; SE-C) on the other domain.

Six heterogeneous profiles of school readiness were also reported in studies. For instance, one heterogeneous profile, tend to average (TA), had various levels of skills in the cognitive dimension of school readiness, with children having low receptive vocabulary but an average level of number knowledge (Fitzpatrick, 2017Fitzpatrick, C. (2017). Ready for kindergarten: Are intelligence skills enough?South African Journal of Childhood Education,7(1), 512.https://doi.org/10.4102/sajce.v7i1.512

https://doi.org/10.1207/s1532480xads0904... ). The tend to strength profile (T +), found in only one study (Tavassolie et al., 2022Tavassolie, T., Bleiker, C., Manfra, L., Hartman, S. C., Dinehart, L. H. B., & Winsler, A. (2022). How profiles of school readiness relate to grade 3 performance among low-income ethnically- and linguistically-diverse children.

https://doi.org/10.1080/10888691.2020.17... ), was characterized by having pre-academic strength and strong to average behavior at school or at home. In contrast, the tend to difficulties profile (T-) (McWayne et al., 2012bMcWayne, C. M., Hahs-Vaughn, D. L., Cheung, K., & Green Wright, L. E. (2012b). National profiles of school readiness skills for Head Start children: An investigation of stability and change.

https://doi.org/10.1080/10888691.2020.17... ) were characterized by low preacademic skills and low-average socioemotional behavior at school or home. Children in the unbalanced cognition profile (UC) were characterized by low socioemotional skills (i.e., high behavior problems at school as rated by the teacher) with low to average pre-academic skills (McWayne et al., 2012aMcWayne, C. M., Cheung, K., Green Wright, L. E., & Hahs-Vaughn, D. L. (2012a). Patterns of school readiness among Head Start children: Meaningful within- group variability during the transition to kindergarten.

https://doi.org/10.1037/a0028884... ). The unbalanced profile (U) had high ratings given by teachers for children’s social ability but performed within the average range on independent assessments of emergent literacy and numeracy (McWayne et al., 2012aMcWayne, C. M., Cheung, K., Green Wright, L. E., & Hahs-Vaughn, D. L. (2012a). Patterns of school readiness among Head Start children: Meaningful within- group variability during the transition to kindergarten. Journal of Educational Psychology, 104(3), 862-878. https://doi.org/10.1037/a0028884
https://doi.org/10.1037/a0028884... ). The last heterogeneous profile is the average cognitive with mixed socioemotional profile (SE↕) (McWayne et al., 2012aMcWayne, C. M., Cheung, K., Green Wright, L. E., & Hahs-Vaughn, D. L. (2012a). Patterns of school readiness among Head Start children: Meaningful within- group variability during the transition to kindergarten.

https://doi.org/10.1037/a0028884... ), with children in this profile having a relatively average pre-academic and mixed socioemotional at home (i.e., average social skills but low behavior problems). Is it worth noting that most of these heterogeneous profiles were found in one or two studies, conducted on Head Start children (McWayne et al., 2012aMcWayne, C. M., Cheung, K., Green Wright, L. E., & Hahs-Vaughn, D. L. (2012a). Patterns of school readiness among Head Start children: Meaningful within- group variability during the transition to kindergarten.

School readiness profiles prior school entry and their associated academic and social outcomes during compulsory education

Among the balanced profiles, children in the high-balanced (B +) profile of school readiness prior school entry had the highest levels of academic achievement and social adjustment during compulsory education. In contrast, children in the Low-Balanced (B-) profile of school readiness had the lowest level of later academic achievement and social adjustment. Little difference was found between the moderate-balanced (M) and the high-balanced (B +) profiles of school readiness on their academic and social adjustment during compulsory education.

In the prediction of academic achievement, no significant difference between unbalanced profiles of school readiness prior school entry was found when the language component of school readiness was controlled for. Without surprise, children in profiles of school readiness characterized by high socioemotional skills (SE + C-, SE + C) better performed in terms of later social adjustment in comparison to school readiness profiles characterized by lower socioemotional skills (SE-C, UC). The high cognitive with low socioemotional profile (C + SE-) of school readiness was the only exception, suggesting that high cognitive skills during the preschool years could help buffer the lack of socioemotional skills at this age in order to help children’s later social adjustment.

At-risk profiles of school readiness

Seven profiles of school readiness prior school entry were low on one domain of school readiness (cognitive or soci- oemotional) or on both domains and thus were considered at risk of later academic and social difficulties. These profiles are described more in-depth. First, the profile of school readiness most at risk of persistent academic and social difficulties during compulsory education was the Low-Balanced profile (B-). Children in this profile had the lowest level of later academic achievement (Christensen et al., 2020Christensen, D., Taylor, C. L., Hancock, K. J., & Zubrick, S. R. (2020).

This profile usually includes, among a normative population, a small proportion of children (between 7 and 13.24%) with low language skills (Christensen et al., 2020Christensen, D., Taylor, C.

https://doi.org/10.4102/sajce.v7i1.512... ), and with low scores (2 SD below the mean) on social/emotional development measures (Hair et al., 2006Hair, E., Halle, T., Terry-Humen, E., Lavelle, B., & Calkins, J. (2006). Children’s school readiness in the ECLS-K: Predictions to academic, health, and social outcomes in first grade.

https://doi.org/10.1016/j.ecresq.2006.09... ). Children with a Low-Balanced profile of school readiness were, in a greater proportion, nonEnglish language learner (Tavassolie et al., 2022Tavassolie, T., Bleiker, C., Manfra, L., Hartman, S.

https://doi.org/10.1080/10888691.2020.17... ). They were also less likely to have attended a preschool program (Quirk et al., 2013Quirk, M., Nylund-Gibson, K., & Furlong, M. (2013).

Australian Journal of Social Issues, ajs4.138. https://doi.org/10.1002/ajs4.138
https://doi.org/10.1002/ajs4.138... ). Males and children with a disability were also overrepresented in the Low-Balanced profile of school readiness (Quirk et al., 2013Quirk, M., Nylund-Gibson, K., & Furlong, M. (2013). Exploring patterns of Latino/a children’s school readiness at kindergarten entry and their relations with grade 2 achievement. Early Childhood Research Quarterly, 28(2), 437-449. https://doi.org/10.1016/j.ecresq.2012.11.002

https://doi.org/10.1080/10888691.2020.17... ).

Three profiles of school readiness had low cognitive abilities and thus were at greater risk of struggling at school: a profile with cognitive difficulty (C-SE), one with high socioemotional and low cognitive skills (SE + C-), and one who tend to difficulties (T-). The cognitive difficulty profile (C-SE) of school readiness included between 7.0 and 19.4% of preschoolers (Hair et al., 2006Hair, E., Halle, T., Terry-Humen, E., Lavelle, B., & Calkins, J. (2006). Children’s school readiness in the ECLS-K: Predictions to academic, health, and social outcomes in first grade. Early Childhood Research Quarterly, 21, 431-454. https://doi.org/10.1016/j.ecresq.2006.09.005
https://doi.org/10.1016/j.ecresq.2006.09... ). At preschool age, children in this profile were below the mean on language and cognition (Hair et al., 2006Hair, E., Halle, T., Terry-Humen, E., Lavelle, B., & Calkins, J. (2006). Children’s school readiness in the ECLS-K: Predictions to academic, health, and social outcomes in first grade. Early Childhood Research Quarterly, 21, 431-454. https://doi.org/10.1016/j.ecresq.2006.09.005
https://doi.org/10.1016/j.ecresq.2006.09... ) and had attention problems or low working memory. They were Hispanic or non-White in a greater proportion (Hair et al., 2006Hair, E., Halle, T., Terry-Humen, E., Lavelle, B., & Calkins, J. (2006). Children’s school readiness in the ECLS-K: Predictions to academic, health, and social outcomes in first grade. Early Childhood Research Quarterly, 21, 431-454. https://doi.org/10.1016/j.ecresq.2006.09.005
https://doi.org/10.1016/j.ecresq.2006.09... ). Males, children with a disability, and those from economically disadvantaged households were also overrepresented in this profile (Hair et al., 2006Hair, E., Halle, T., Terry-Humen, E., Lavelle, B., & Calkins, J. (2006). Children’s school readiness in the ECLS-K: Predictions to academic, health, and social outcomes in first grade. Early Childhood Research Quarterly, 21, 431-454. https://doi.org/10.1016/j.ecresq.2006.09.005
https://doi.org/10.1016/j.ecresq.2006.09... ). They also performed poorly at math and reading assessment during the formal school years (Hair et al., 2006Hair, E., Halle, T., Terry-Humen, E., Lavelle, B., & Calkins, J. (2006). Children’s school readiness in the ECLS-K: Predictions to academic, health, and social outcomes in first grade. Early Childhood Research Quarterly, 21, 431-454. https://doi.org/10.1016/j.ecresq.2006.09.005
https://doi.org/10.1016/j.ecresq.2006.09... ).

The high socioemotional and low cognitive skills profile (SE + C-) of school readiness was found in only two studies (Hair et al., 2006Hair, E., Halle, T., Terry-Humen, E., Lavelle, B., & Calkins, J. (2006). Children’s school readiness in the ECLS-K: Predictions to academic, health, and social outcomes in first grade. Early Childhood Research Quarterly, 21, 431-454. https://doi.org/10.1016/j.ecresq.2006.09.005

Early Childhood Research Quarterly, 28(2), 437-449. https://doi.org/10.1016/j.ecresq.2012.11.002
https://doi.org/10.1016/j.ecresq.2012.11... ) and included between 17.0 to 33.9% of the preschoolers. These children were, in a greater proportion, from mothers and fathers not speaking English to the child (Hair et al., 2006Hair, E., Halle, T., Terry-Humen, E., Lavelle, B., & Calkins, J. (2006). Children’s school readiness in the ECLS-K: Predictions to academic, health, and social outcomes in first grade. Early Childhood Research Quarterly, 21, 431-454. https://doi.org/10.1016/j.ecresq.2006.09.005
https://doi.org/10.1016/j.ecresq.2006.09... ). They also had significantly lower English proficiency scores prior school entry and less exposure to preschool program (Quirk et al., 2013Quirk, M., Nylund-Gibson, K., & Furlong, M. (2013). Exploring patterns of Latino/a children’s school readiness at kindergarten entry and their relations with grade 2 achievement. Early Childhood Research Quarterly, 28(2), 437-449. https://doi.org/10.1016/j.ecresq.2012.11.002
https://doi.org/10.1016/j.ecresq.2012.11... ). However, this group of children did not perform significantly lower than children in the Low-Balanced profile with regard to their later academic achievement (Quirk et al., 2013Quirk, M., Nylund-Gibson, K., & Furlong, M. (2013). Exploring patterns of Latino/a children’s school readiness at kindergarten entry and their relations with grade 2 achievement.

https://doi.org/10.1016/j.ecresq.2012.11... ). Similarly, the tend to difficulties profile (T-) was reported in only two studies (McWayne et al., 2012bMcWayne, C. M., Hahs-Vaughn, D. L., Cheung, K., & Green Wright, L. E. (2012b). National profiles of school readiness skills for Head Start children: An investigation of stability and change.

https://doi.org/10.1080/10888691.2020.17... ). Children from a linguistic minority as well as ethnical minority such as Latino and Black preschoolers had increased odds of being in this profile of school readiness (McWayne et al., 2012bMcWayne, C. M., Hahs-Vaughn, D. L., Cheung, K., & Green Wright, L. E. (2012b). National profiles of school readiness skills for Head Start children: An investigation of stability and change.

(2012b). National profiles of school readiness skills for Head Start children: An investigation of stability and change.

(2022). How profiles of school readiness relate to grade 3 performance among low-income ethnically- and linguistically-diverse children.

https://doi.org/10.1080/10888691.2020.17... ) were also overrepresented in this profile. This profile, although being at risk, had greater academic achievement during compulsory education (grade 3 GPA, reading and math test scores) in comparison to the Low-Balanced profile of school readiness (Tavassolie et al., 2022Tavassolie, T., Bleiker, C., Manfra, L., Hartman, S. C., Dinehart, L. H. B., & Winsler, A. (2022). How profiles of school readiness relate to grade 3 performance among low-income ethnically- and linguistically-diverse children.

https://doi.org/10.1080/10888691.2020.17... ).

Three additional profiles of school readiness with low socioemotional abilities at preschool age were at greater risk of persistent difficulties during the school years: a profile with socioemotional difficulty (SE-C), one with high cognitive and low socioemotional skills (SE + C-), and one with unbalanced cognition (UC). The soci- oemotional difficulty profile (SE-C) of school readiness included between 7 and 17% of preschoolers (Christensen et al., 2020Christensen, D., Taylor, C. L., Hancock, K. J., & Zubrick, S. R. (2020). School readiness is more than the child: A latent class analysis of child, family, school and community aspects of school readiness.

https://doi.org/10.1207/s1532480xads0904... ). Children in this profile had an increased likelihood of vulnerability in later social competence and emotional maturity and a poor teacher–child relationship (Christensen et al., 2020Christensen, D., Taylor, C. L., Hancock, K. J., & Zubrick, S. R. (2020). School readiness is more than the child: A latent class analysis of child, family, school and community aspects of school readiness. Australian Journal of Social Issues, ajs4.138. https://doi.org/10.1002/ajs4.138
https://doi.org/10.1002/ajs4.138... ). They had the highest proportion of non-White children, and of families classified as poor (Konold & Pianta, 2005Konold, T. R., & Pianta, R. C. (2005). Empirically-derived, person-oriented patterns of school readiness in typically-developing children: Description and prediction to first-grade achievement.

https://doi.org/10.1207/s1532480xads0904... ), and the lowest home quality score. In terms of academic and social outcomes, this profile of children had the lowest level of engagement at school in Grade 5 (Sabol & Pianta, 2012Sabol, T. J., & Pianta, R. C. (2012). Patterns of school readiness forecast achievement and socioemotional development at the end of elementary school. Child Development, 83(1), 282-299. https://doi.org/10.1111/j.1467-8624.2011.01678.x
https://doi.org/10.1111/j.1467-8624.2011... ), but did not differ from other profiles in achievement test performance in Grade 1 (Konold & Pianta, 2005Konold, T. R., & Pianta, R. C. (2005). Empirically-derived, person-oriented patterns of school readiness in typically-developing children: Description and prediction to first-grade achievement.

https://doi.org/10.1207/s1532480xads0904... ) and in terms of executive functions in Grade 9 (age 15; Goble et al., 2019Goble, P., Pianta, R. C., & Sabol, T. J. (2019).

https://doi.org/10.1080/10888691.2018.14... ). The high cognitive and low socioemotional skills profile (SE + C-) of school readiness included about 22% of preschoolers (Konold & Pianta, 2005Konold, T. R., & Pianta, R. C. (2005).

https://doi.org/10.1207/s1532480xads0904... ), with a greater proportion of non-Whites children. They were characterized by elevated reported externalizing behaviors, but they had high working memory (and overall cognitive skills) during the preschool years. Mothers of children in this school readiness profile had more years of education than mothers of children in most of the other school readiness profiles. Interestingly, the SE + C- profile of school readiness had low teacher-reported disruptive behavior disorders during compulsory education, the highest score in math and reading performance in Grade 5 (Sabol & Pianta, 2012Sabol, T. J., & Pianta, R. C. (2012). Patterns of school readiness forecast achievement and socioemotional development at the end of elementary school. Child Development, 83(1), 282-299. https://doi.org/10.1111/j.1467-8624.2011.01678.x
https://doi.org/10.1111/j.1467-8624.2011... ), and higher GPA, math and literacy skills, and executive functions in Grade 9 (Goble et al., 2019Goble, P., Pianta, R. C., & Sabol, T. J. (2019). Forecasting youth adjustment at age 15 from school readiness profiles at 54 months. Applied Developmental Science, 23(4), 353-370. https://doi.org/10.1080/10888691.2018.1436439
https://doi.org/10.1080/10888691.2018.14... ). In other words, despite having low socioemotional skills at preschool age, children in this profile of school readiness did not manifest later academic or social difficulties. At last, the unbalanced cognition profile (UC), reported in only one study (McWayne et al., 2012aMcWayne, C. M., Cheung, K., Green Wright, L. E., & Hahs-Vaughn, D. L. (2012a). Patterns of school readiness among Head Start children: Meaningful within- group variability during the transition to kindergarten. Journal of Educational Psychology, 104(3), 862-878. https://doi.org/10.1037/a0028884
https://doi.org/10.1037/a0028884... ), represented 17% of preschoolers. In this profile, there were significantly more boys, linguistic and ethnic minority children, and children with diagnosed disabilities.

Discussion

This study advanced knowledge on profiles of school readiness and how it predicts later academic and social adjustment by reviewing studies using a person-centered approach. In this systematic review, we identified 15 profiles of school readiness: 3 balanced, 6 unbalanced, and 6 heterogenous profiles. The balanced profiles were the most frequently reported, while the heterogenous ones were the profiles less frequently reported in studies. Notable differences were found between the 15 profiles of school readiness. By highlighting these findings and by identifying 15 profiles of school readiness, each of them being differently associated with social and academic outcomes, this systematic review supports the relevance of studying school readiness with a person-centered approach. For instance, in the present study, we found evidence that considering profiles of school readiness can help forecast which children will experience difficulties. In particular, we identified seven profiles that were at risk of later academic and social difficulties, with the Low Balanced (B-) being the most at-risk profile. Despite variation in the levels of cognition and/or socioemotional skills, most of these at-risk profiles of school readiness shared similar features. These at-risk profiles of school readiness had subsequent lower academic and/or social outcomes.

These findings can help designing early preventive intervention for children with at-risk profiles of school readiness. Children being in an at-risk profile of school readiness were from a linguistic and/or visible minority family in a greater proportion and had elevated family risk factors such as a low home quality, low socioeconomic status, and low maternal educational attainment. Furthermore, they did not attend a preschool program and/or had a diagnosed disability. Boys also tended to belong to at-risk profiles of school readiness leading to lower academic and social outcomes. Thus, these children should deserve special attention to alleviate later academic and social difficulties. The attention given to these at-risk children should also persist in the early school years.

One potential approach to promote academic and social adjustment among children with initial risk of underachievement is to promote the accessibility to high-quality childcare arrangements. Evidence of preschool childcare attendance on school readiness and social outcomes during childhood has been convincing (Geoffroy et al., 2010Geoffroy, M.-C., Côté, S. M., Giguère, C.-E., Dionne, G., Zelazo, P. D., Tremblay, R. E., Boivin, M., & Séguin, R. J. (2010). Closing the gap in academic readiness and achievement: The role of early childcare.

https://doi.org/10.1016/j.econedurev.200... ). Previous studies found direct associations between preschool childcare attendance and children’s later academic and social outcomes (Ansari, 2018Ansari, A. (2018).

https://doi.org/10.1146/annurev.psych.03... ), especially for children of mothers with low levels of education (Geoffroy et al., 2010Geoffroy, M.-C., Côté, S.

https://doi.org/10.1542/peds.2015-0419... ). Parent involvement in intervention program with both home- and school-based components is also another approach to promote school readiness among at-risk children (Marti et al., 2018Marti, M., Merz, E. C., Repka, K. R., Landers, C., Noble, K. G., & Duch, H. (2018). Parent involvement in the Getting Ready for School intervention is associated with changes in school readiness skills. Frontiers in Psychology, 9, 759. https://doi.org/10.3389/fpsyg.2018.0075
https://doi.org/10.3389/fpsyg.2018.0075... ), as well as programs capitalizing on early childhood educators training (Brown et al., 2009Brown, J. R., Knoche, L. L., Edwards, C. P., & Sheridan, S. M. (2009). Professional development: A case study of early childhood professionals in the Getting Ready Project. Early Education and Development, 20, 482-506.). In particular, programs focusing on responsive parent–child and educator-child interactions as well as parent-educator partnerships have been proved effective (Waters & Catlett, 2020Waters, C. L., & Catlett, C. (2020). From article to action: Strategies for promoting parent-professional relationships and parent-child interactions. Young Exceptional Children, 23(1), 52-53. https://doi.org/10.1177/1096250619890431
https://doi.org/10.1177/1096250619890431... ).

Limitations and recommendations for future studies

This systematic review has limitations that must be mentioned to clearly confine its results. First, only studies undertaking a multidimensional conceptualization of school readiness were selected. These studies had to include at least one cognitive and one socioemotional indicator of school readiness. Similarly, this systematic review only included studies focusing on academic and social outcomes during compulsory education. Thus, it excludes studies investigating other outcomes such as health-related ones and studies focusing on the predictors of school readiness profiles. Second, some specific results from the selected studies, hard to summarize within the current review, were omitted in the tables. We also, sometimes, grouped several profiles obtained in a study under one profile of school readiness. For instance, McWayne et al. (2012a)McWayne, C. M., Cheung, K., Green Wright, L. E., & Hahs-Vaughn, D. L. (2012a). Patterns of school readiness among Head Start children: Meaningful within- group variability during the transition to kindergarten. Journal of Educational Psychology, 104(3), 862-878. https://doi.org/10.1037/a0028884
https://doi.org/10.1037/a0028884... detected two profiles of school readiness that had similar cognitive levels, but one of these profiles had lower levels of socioemotional skills at home. These two profiles were both grouped in the average cognitive with mixed socioemotional profile. This choice brought a more understandable portrait of the existing literature but also hides some fine nuances found in some studies. Third, this systematic review is mainly based on studies conducted on the general population of children or on children from families with a low socioeconomic status. Other profiles of school readiness, not identified in the current review, might exist among children with specific vulnerabilities. Future literature reviews would benefit from replicating our findings with studies on at-risk children, as different profiles of school readiness could emerge in such populations.

Conclusion

Examining profiles of school readiness before school entry matters for children’s academic and social adjustment. This systematic review disentangled 15 profiles of school readiness based on the child level of cognitive and socioemotional skills, with 7 profiles being systematically associated with worse academic achievement and social adjustment. Most of these at-risk profiles of school readiness were from a linguistic and/or visible minority family and had elevated family risk factors, and these at-risk children (boys in a greater proportion) did not participate to a preschool program. These findings have implications for early identification of at-risk children, as it gives a clear portrait of children from preschool age showing lower school readiness and higher risk for social and academic underachievement.

This systematic review also highlighted areas of consensus and existing gaps. While all studies incorporated the cognitive and socioemotional dimensions of school readiness, only half of the studies included all dimensions of school readiness. As such, research would benefit of a consensus on essential indicators of school readiness. Future studies should also continue to study school readiness with a person-centered approach to facilitate the screening of children most at risk of poor academic achievement and social adjustment and the need for early intervention.
