Notes: The U.S. Department of Education’s Office for Civil Rights occasionally updates the underlying dataset. ProPublica may update the interactive’s data in response.

Disparity scores are not available if there are too few students in a specific racial group to make a statistically significant calculation. They are also not available if data about a particular racial group was not reported. Some schools or districts reported an overcount of students in a disparity category (such as suspensions or AP courses) when compared with the total enrollment of that particular student group. In such cases, we also omit the disparity score.

Due to rounding, demographic breakdowns in composition charts may add up to more than 100 percent.

The racial categories we show data for are: Black, Hispanic, White, Asian/Pacific Islander or Native Hawaiian, Two or More Races, and Native American or Alaska Native. In some cases, we abbreviate the last three of these racial groups to Asian, Two+ Races, and Native Am.

Due to a technical issue with the Office for Civil Rights’ collection of data on sworn law enforcement officers in schools, the data for security staff may be an undercount.

As with any self-reported data, there may be errors in the federal Civil Rights Data Collection. Though districts are required to ensure the accuracy of their data, some may still report incorrect figures. Additionally, for some variables, the CRDC rounds the number of students for privacy reasons. In these cases, groups of students may represent a slight undercount or overcount.

Data specific to high school testing or high school level courses (including geometry, biology, calculus, AP enrollment, SAT testing rates, etc.) is calculated out of total high school enrollment, while data for other classes (such as eighth-grade algebra) is calculated out of total student enrollment.
