Gap or gaps - Challenging the singular definition of the achievement gap

For decades, researchers examined the achievement gap between minority and nonminority students. This singular definition of achievement gap ignores important within-group differences. This article uses National Education Longitudinal Study (NELS:88) data to examine within-group differences and compares those across Latino, African American, and White populations. Results question the singular definition of achievement gap. Given the importance of how issues are defined, a singular definition of achievement gap may mean current policies miss the mark in raising achievement levels between and within groups.
