Overall score, as TEA published it in 2025-26. Measured across Dallas County school districts, of which 14 districts are ranked below.
What this ranking counts
14 districts of 14 districts are ranked here.
Ordered from the lowest figure upward.
5 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: Dallas County school districts with the highest overall score. Both ends are published, because a site that prints only the flattering half of an ordering is advertising.
