A new study published in the latest issue of Gifted Education Quarterly examines the long-term impact on young students of skipping a grade (also known as acceleration) on subsequent academic outcomes. Analysts used the National Education Longitudinal Study database (NELS) to begin tracking a representative cohort of eighth-grade students in 1988, then follow them through high school and again two and eight years post-high school (i.e., through 2000). A variety of outcome data were collected, including PSAT, SAT, and ACT scores, students’ GPAs, and college aspirations—as well as college measures, such as the selectivity of the institution, GPA for each college year, and degree attainment. All students who had ever skipped at least one grade prior to eighth grade comprised the acceleration group. Thus, the sample included kids who ranged from age nine to age thirteen while in eighth grade (the mean age was 12.7). Those students were then matched with a set of older, non-accelerated, same-grade peers from NELS based on gender, race, SES, and eighth-grade achievement. The accelerated and non-accelerated groups were nearly identical on these variables.
The study found that accelerated students scored significantly higher on the math sections of the PSAT, SAT, and most of the ACT and earned higher grades in high school. They also took more advanced courses and more often participated in additional educational opportunities. Once in college, they earned higher grades during their second year and overall. (Among the few similarities was that both groups were admitted to similarly selective colleges, and both had similar rates of graduate degree completion, although accelerated kids were slightly more likely to attain a bachelor’s degree.) More advanced students, of course, are also likelier to be more self-motivated in general, which may explain their better performance on most measures. Nevertheless, accelerated kids keep doing things to help them accelerate. We should applaud and encourage that.
