! Interpret data with caution. Users are cautioned against performing t-tests on cells with NAEP proficiency estimates that have been calculated with less than 62 observations (N). NAEP considers a cell size of 62 the minimum required for performing meaningful comparisons.

‡ Reporting standards not met. Means and standard errors based on less than 30 observations are not reported.

¹ American Indian includes Alaska Native, Black includes African American, Pacific Islander includes Native Hawaiian, and Hispanic includes Latino. Race categories exclude Hispanic origin unless specified.
