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…

The belief that additional time allows children to become more ready for school has affected public policy and individual practices. Prior studies estimated either associations between school entry age and academic growth or causal effects on achievement measured at one or two points. This article contributes novel causal evidence for the impacts…

Few elementary students on the Commonwealth of the Northern Mariana Islands (CNMI) are scoring at grade level or higher on the ACT Aspire reading assessment. To better understand factors associated with the reading proficiency of CNMI grade 3 students, stakeholders there asked the Regional Educational Laboratory Pacific to examine the demographic…

Few elementary students in the Commonwealth of the Northern Mariana Islands (CNMI) are scoring at grade level or higher on the ACT Aspire reading assessment. This study examined data on students who enrolled in grade 3 in a CNMI public school from 2014/15 to 2018/19 to understand their grade 3 reading performance. The study used administrative…

This research investigated whether delayed school entry was associated with higher achievement in national tests of reading and numeracy in Grades 3, 5, 7, and 9 (n = 2,823). Delayed entry was related to advantages in reading (0.14 SD) and numeracy (0.08 SD) at Grade 3, although little variance was explained (1%-2%). This slight advantage…

In the United States, when a child turns five years of age, he or she is eligible to enroll and attend five-year old kindergarten. Parents and caregivers are often tasked with making the decision on whether or not to enroll their child when eligible to attend kindergarten or if the child should be held back another year (redshirted) and attend…

The education laws of each country establish starting cutoff dates for compulsory education which could, potentially, affect students' academic achievement. Specifically, they could be detrimental for those students whose birthday is just before the school entry cutoff, as they will be the youngest in their classroom, while it could boost the…

With the introduction of the 4+4+4 education system in 2012, the school starting age has been reduced to 60 months and branch teachers started to attend classes starting from 5th grade. Therefore, in the current study, there are two aims. Firstly it is aimed to determine the opinions and experiences of science teachers having started to teach the…

Purpose: We investigated the roles of leisure reading and word reading ability in vocabulary and reading comprehension development in 598 adolescents at ages 10, 11, and 12 (285 girls, 313 boys). Method: Structural equation modeling was used to test whether word reading was associated with vocabulary and reading comprehension: a) directly; b)…

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…

There are sizable and pervasive academic achievement gaps between minority and non-minority students in the United States. Non-minority students -- particularly boys -- are more likely to enroll in school one year after they become eligible, a practice known as 'redshirting.' Consequently, non-minority students are on average more mature than…

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…
