Quick validation snapshot
New Hampshire has the highest estimate (95.0%); California has the lowest (84.8%). The U.S. benchmark is 89.9%. These are useful checks when importing the CSV into a spreadsheet. Reference jurisdictions may lie outside the 50-state range, so exclude rows marked reference when reproducing the default state ranks.
Margins of error are 90% survey margins. Preserve them when reshaping the data; an empty cell and a numeric zero have different meanings.
Calculation and reproducibility
Published estimate; no transformation of the value.

Limits and reuse
Adult attainment is not a current high school graduation rate and does not directly rate school quality.
