TNTP gathered teacher and student racial demographic data for as many years as it is available. We have aggregated data in all 47 states where teacher demographic data is collected. 

Teacher data is sourced from state departments of education and other publicly available information. 

Student data is sourced from the National Center for Education Statistics. 

Data date ranges: 

• Of the 47 states (plus the District of Columbia), 43 have current student and teacher data for the 2022-23 school year.  

• Hawaii, Rhode Island, South Carolina, and Tennessee’s most recent data is from the 2021-22 school year, and California has data from 2018-19.  

• Maine, New Hampshire, and Vermont rely on survey data from the 2020-21 school year.  

TNTP has not independently verified the accuracy of the data provided by these governmental agencies.

Our goal is to include demographic data on as many public school teachers and students as possible—traditional public schools, charter schools, and specialized schools. Charter school data is integrated into the analysis when available, specifically within the traditional school district in which the charter school is located. 

Review our data sources for detailed information on whether charter schools are included based on state data availability. 

Data for specialized schools such as adult education, pre-K, regional schools, prison-based schools, schools on military bases, schools serving deaf and blind students, and virtual schools, are rarely available but included if so. 

These dashboards define a person of color as someone who identifies as one of the following six race categories established by the National Center for Education Statistics: American Indian or Alaskan Native, Asian, Black or African American, Hispanic or Latinx, Native Hawaiian or Pacific Islander, or two or more races. 

The student-teacher diversity gap represents the percentage of students that identify as a person of color minus the percentage of teachers that identify as a person of color. 

• National Student and Teacher Demographics Maps: The data shown represents the most recent year for which the state makes data available. See detailed data documentation by state for further details. 

• Detailed Student and Teacher Demographics: The “United States” student and teacher counts include the most recent year of data for all states where detailed race/ethnicity is available. Data for all race/ethnicity categories is not available in Idaho, Maine, New Hampshire, Nevada, North Carolina, and Vermont — these states are not included in the “United States” counts. 

• Trends in Student and Teacher Demographics: The “United States” student and teacher counts include states that have five years of data from the 2017-2018 school year through the 2022-23 school year. The following states do not meet these criteria and are excluded: California, Connecticut, the District of Columbia, Hawaii, Idaho, Maine, Maryland, Mississippi, New Hampshire, Rhode Island, South Carolina, Tennessee, Vermont, and Virginia. 

• June 4, 2024: Initial launch of the webpage containing three data dashboards — National Student and Teacher Demographics Map, Detailed Student and Teacher Demographics, Trends in Student and Teacher Demographics.
