Education
rankings by state.

Choose a qualification threshold, not a school grade

All three measures here describe adults age 25 and older. High school attainment includes those with college degrees; bachelor’s attainment includes those with advanced degrees. The categories overlap, so adding the percentages would double count people. These measures describe current residents, including adults educated elsewhere. Migration, age composition and employment patterns can affect the shares without any change in the performance of local schools.

Use the same qualification threshold and year for a state comparison. An attainment rank is not a test-score rank, student graduation rate or school-quality evaluation. Read margins of error before interpreting a one-place difference, and use the comparison tool for two-state significance checks. Within-state differences between overlapping qualifications need a different variance calculation; the independent-state test does not apply to them.

Choose the measure that answers your question

The linked pages retain exact source precision for ranks, show true ties, and display uncertainty where it is available. The comparison tool lets you inspect selected states without changing their rank among the full 50-state universe. Shared comparisons preserve their data edition.
