Achievement Gaps

Achievement gaps occur when one group of students (e.g., students grouped by race/ethnicity, gender) outperforms another group and the difference in average scores for the two groups is statistically significant (i.e., larger than the margin of error). NCES explored the achievement gaps between Black and White, and Hispanic and White, students using NAEP data to illuminate patterns and changes in these gaps over time, and identify factors that might underlie such gaps. These results are expected to be helpful to those interested in the improvement of education of our children.
