Relative age effects (RAEs) explain the (dis)advantages individuals experience as a result of when they are born relative to a pre-determined cut-off date. Within an interuniversity setting, academic timing (AT) may moderate the RAE pattern due to some student-athletes having eligibility years that do not correspond with their birth years. The…

Differences between monolingual and multilingual vocabulary development have been observed but few studies provide a longitudinal perspective on vocabulary development before and following school entry. This study compares vocabulary growth profiles of 106 multilingual children to 211 monolingual peers before and after school entry to examine…

The age at which students enter school is increasing. More parents are delaying their child's entry, and U.S. states are moving school entry cutoffs earlier, mainly because older students outperform younger ones on many educational outcomes. Much of the literature interprets advantages held by older students as benefits to entering school older,…

In this paper, we estimate the effect of pupil's relative age within the first grade of primary school on mathematics and reading test scores at age 15. The main objective is to evaluate the long-term causal effect of relative age in the first grades of primary school on pupil's test in 16 different countries. We use the national rule for…

This study compared the academic and social development of students who entered grade 1 very early (5:6 years or 5:7 years), in the mid range (5:8 to 6:3 years), and very late (6:4 years or older). The purpose of the study was to explore the hypothesis that the early grade 1 entrants would have continuing problems in both academic and social…
