Grade retention has been the focus of the education debate in Spain for decades. On average, more than 30% of students have repeated at least one grade before they finish (or dropout from) their compulsory studies. The present research provides new evidence on this issue by investigating the influence of Spain's school entry age upon students'…

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…

High school graduation rates are a central policy topic in the United States and have been shown to be stagnant for the past three decades. Using student-level administrative data from New York City Public Schools, I examine the impact of compulsory school attendance on high school graduation rates and grade attainment, focusing the analysis on…

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…

Using a rich data set of all SAT test takers from the 2004 through 2008 high school graduation cohorts, we investigate the impact of state-specific school age-of-entry laws on students' pathways into and through college. We document that these laws do not impact the probability that a student takes the SAT; however, we find strong evidence that…

It is an attempt to evaluate the hypothesis that older students fare better academically than their younger classmates. Findings indicate that on average…
