Where Gifted Testing Actually Happens: The Largest US School Districts

Gifted identification is run district by district, so where the large districts are is where most families meet this process at all. We analysed the 1,945 largest US school districts — those serving 5,000 students or more — using federal enrollment data.

Methodology

Figures are computed live from the iPrepGenius question bank (131,000+verified, unretired practice questions at the time you loaded this page). Our banks are original practice content modeled on each test's published blueprint and format; they are not actual test items, and findings describe our bank's composition — a faithful proxy for, but not a publication of, the tests themselves. Difficulty ratings use our 1–5 scale assigned at generation and refined by calibration. Aggregated practice statistics, where shown, are fully anonymized.
