State Assessment Data Repository

Data Availability

The repository covers all 50 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands, with the earliest year ranging from 1998 to 2018 by state. The map shows how many years of data each state has; the table below lists the exact year range and subjects.

There may be intermittent missing years if a state did not publish data - for example, while field-testing a new assessment. No state administered assessments in Spring 2020 due to COVID-19. See the methodology for details.
