Achievement Gap
Updated: July 7, 2011
The “achievement gap” in education refers to the disparity in academic performance between groups of students. The achievement gap shows up in grades, standardized-test scores, course selection, dropout rates, and college-completion rates, among other success measures. It is most often used to describe the troubling performance gaps between African-American and Hispanic students, at the lower end of the performance scale, and their non-Hispanic white peers, and the similar academic disparity between students from low-income families and those who are better off. In the past decade, though, scholars and policymakers have begun to focus increasing attention on other achievement gaps, such as those based on sex, English-language proficiency and learning disabilities.

With the passage of the **No Child Left Behind Act of 2001**, closing achievement gaps among these various student groups became a focus of federal education accountability, and schools and districts were required to disaggregate student test scores and other performance data by student characteristics to enable better comparisons between groups. This created both to greater awareness of racial disparities and to rising concern about other kinds of achievement gaps. The attention led to more targeted interventions for different groups of students, but had not closed most achievement gaps to an appreciable degree a decade of the law passed.
