School Entry Deferral: Effects of Age and Schooling on Children's Longitudinal Executive Function Development and Parent-Reported Socio-Emotional and Regulatory Outcomes.
Simpson HG, Chevalier N, Booth JN ·
Summary
Written by AI, not yet AICS's view · claude-haiku-4-5-20251001This study followed 110 children over one school year to understand how delaying school entry affects their thinking skills and emotional development. Children who started school later showed better social and emotional skills reported by parents, while all children who entered school benefited in working memory development. Older children had stronger thinking skills at the start of school, but these differences narrowed by the end of the year.
Key points
- School entry deferral was associated with improved parent-reported socio-emotional and self-regulatory outcomes, especially in children with initially lower scores
- Schooling benefited working memory progress across all groups
- Older children started school with better working memory and inhibitory control than younger school entrants
- Baseline differences in executive function between older and younger starters had partly reduced over the school year
- Regulatory skills appear important in both cognitive and socio-emotional development when considering school entry age
Limitations
The study did not examine academic outcomes, only executive function and parent-reported socio-emotional measures. The sample was predominantly White, limiting generalizability to diverse populations.
Abstract
Whether an optimal school-entry age exists is widely debated. A sequential cohort longitudinal design was used to investigate how school-entry deferral affected executive function development, and parent-reported socio-emotional and self-regulatory outcomes in 110 children (majority White) over one academic year. Groups comprised: 35 Deferred School Entrants (Mage = 66 months, 17 females), 31 Non-deferred School Entrants (Mage = 57 months, 13 females), and 44 Deferred Pre-schoolers (Mage = 55 months, 22 females). Deferral was associated with improved parent-reported socio-emotional and self-regulatory outcomes, especially in children with initially lower scores, while schooling benefited working memory progress. Further, older children started school with better working memory and inhibitory control relative to younger school entrants, although baseline differences had partly waned over the school year. These results highlight the value of accounting for regulatory skills underlying both cognitive and socio-emotional outcomes within school entrance age debates. Further research is required to determine if, and how, this might relate to academic outcomes.
Findings the Hub has extracted
Each claim below is labelled by its type of design and links back to this report.
- Intervention
- School entry deferral (delaying school entry by one year while peers started school)
- Population
- 110 children (majority White), aged approximately 55–66 months at baseline, comprising deferred school entrants, non-deferred school entrants, and deferred pre-schoolers
Key finding
Deferred school entrants showed improved parent-reported socio-emotional and self-regulatory outcomes compared to non-deferred entrants
