About high school graduation rate
What this measures: Share of 9th-graders who earn a regular diploma within four years, adjusted for transfers in and out.
Why it matters: On-time graduation is a key checkpoint, predicting earnings, civic engagement, and reduced incarceration risk.
Watch out: Measures on-time diplomas, not learning. A high graduation rate can coexist with weak college readiness.
