Ranked list · Harris County school districts
Harris County school districts with the largest overall score gains since 2021-22
19 districts · since 2021-22 · TEA data fetched 15 August 2026
The change in overall score since 2021-22, from TEA's re-scored "2021-22 What If" figure to the figure it published for 2025-26. TEA re-scored 2021-22 under the rules it adopted for 2022-23 and publishes that re-scoring as "2021-22 What If". This ranking reads the re-scored series, so the change spans one consistent methodology rather than a break. Measured across Harris County school districts, of which 19 districts are ranked below.
What this ranking counts
19 districts of 19 districts are ranked here.
Ordered by the largest rise first. A negative figure is a decline.
11 of the ranked districts share a placement with at least one other. Tied districts print the same placement and the next placement skips, so two districts sharing 3rd are both 3rd and the one behind them is 5th.
A ranking by a raw figure is not a measure of teaching quality on its own: it correlates with school size and, more strongly, with how many of a school's students live in poverty. Every entity page on this site instead compares a school against a peer group — districts with districts, campuses with campuses — whose share of economically disadvantaged students falls within 10 percentage points of its own, because a comparison against the state average measures the composition of a school's intake at least as much as anything the school did. This list does not: it orders by the raw figure alone. How the peer group is chosen.

The other end, and the other lists
The other end of this list: Harris County school districts with the largest overall score declines. Both ends are published, because a site that prints only the flattering half of an ordering is advertising.
