Mapping High School Graduation Rates Across the United States

Tracking academic success through graduation rates offers a window into the varied rigor of state education systems. While a high school diploma remains a reliable indicator of future economic stability—with Census data showing that degree holders earn an average of $8,216 more annually than their peers—the path to that credential is not uniform. Requirements for testing and coursework differ significantly by state, complicating direct comparisons between regions.

Most states utilize the four-year adjusted cohort graduation rate, a formula that tracks first-time ninth graders while accounting for transfers, emigration, and mortality. While the National Center for Education Statistics provides official benchmarks, their reporting often trails by several years. To capture the current landscape, recent data from state education agencies for the 2024-2025 school year—and 2023-2024 for a subset of states including Texas and Ohio—provide a more immediate view of how schools are performing against the national average.
