Gauging the Gaps, a new Education Trust report, warns that looking at achievement gaps is misleading.
For example, one might want to congratulate Oklahoma for having a small black-white gap in eighth-grade mathematics on the National Assessment of Educational Progress (NAEP). But a closer look shows that the gap is among the smallest in the country because Oklahoma’s white eighth-graders — the students at the top of this gap — are among the lowest performing white students in the country.
Delaware, Florida, Massachusetts and Texas have done the best at closing gaps and improving achievement, EdTrust reports. Vermont, which has little racial diversity, does well with low-income students.
