There is growing evidence that school starting age impacts children's likelihood of receiving special education services, but less is known about variations in this effect. Using a regression discontinuity design, I found that the youngest students in a kindergarten cohort are 40% more likely (p < 0.001) to be placed in special education than…

This study investigated whether there are significant differences between reading achievements of 15-year-old students and starting age for preschool and socioeconomic factors according to the results from the PISA 2015 and 2018. The quantitative results show that there is a clear and statistically significant difference between reading test…

Nearly 14% of students in the United States receive special education services in public schools (NCES, 2017). Special education programs serve students with a wide range of developmental differences and vary considerably across schools and districts (National Research Council, 1997). Likelihood of identification for special education services…

Early years are a critical period for skill development. In this sense, the Early Childhood Education and Care (ECEC) programmes have an important role in promoting children's learning during this period. This study aimed to explore the effectiveness of ECEC programmes by analysing the relationship between students' ECEC attendance and their later…

Much of the literature estimating disproportionality in special education identification rates has focused on socioeconomic status, race, and gender. However, recent evidence suggests that a student's school starting age also impacts the likelihood they receive special education services, particularly in the early grades. I build on the evidence…

We present evidence of a positive relationship between school starting age and children's cognitive development from ages 6 to 18 using a fuzzy regression discontinuity design and large-scale population-level birth and school data from the state of Florida. We estimate effects of being old for grade (being born in September vs. August) that are…

This quantitative study examined the effect of a student's entry point into a school district and his/her performance on the New York State English Language Arts and Integrated Algebras Regents Exams. The subjects of this study were students assigned to the 2010 and 2011 cohorts from one Long Island school district. Three entry points were…

There is continuing controversy about the optimal or appropriate age at which children should start school. The purpose of this study is to examine the relationship between age and achievement. It is an attempt to evaluate the hypothesis that older students fare better academically than their younger classmates. Findings indicate that on average…
