- Definition: Share of public high school students who graduate with a regular diploma within four years of starting grade 9, adjusted for students who transfer in, transfer out, emigrate or die (the 4-year adjusted cohort graduation rate, ACGR), as a percentage. From the NCES Digest of Education Statistics, based on state reports to the U.S. Department of Education. The year is the end of the school year (2022 means 2021-22).
- Note: States set their own diploma requirements, so rates are not fully comparable between states. 2011-12 rates are published as whole numbers. The national rate covers the 50 states and the District of Columbia; NCES estimates parts of it where a state did not report.
