Summary:
The six middle schools in Santa Ana Unified serve grades 6–8, with 2025–2026 results showing substantial differences from school to school. The six-school averages were 31% proficient in ELA, 20% in math and 16% in science, compared with state results of 49%, 38% and 36%; the most important finding is that average performance trails the state by about 18 to 20 points in every subject.
Douglas MacArthur leads ELA at 48%, 7 points ahead of runner-up Mendez, and science at 29%, 11 points ahead of Villa. MacArthur is still 1 point below the state in ELA and 7 points below in science. Mendez leads math at 40%, 9 points ahead of MacArthur, and is 1 point above the state. At the bottom, Willard has the lowest ELA and math results, 15% and 7%—34 and 31 points below the state. Lathrop has the lowest science result, 10%, 26 points below the state.
From 2024–2025 to 2025–2026, the group averages were nearly unchanged in ELA and math and rose 1 point in science; state results rose 0, 1 and 3 points, respectively, so the science gap widened by 3 points. There are school-level exceptions: Carr gained 3 points in ELA and 5 in science, while Willard improved in all three subjects but remains lowest in ELA and math. SchoolDigger gives MacArthur and Mendez three stars and rankings in the 53rd and 50th percentiles; Lathrop and Willard have no stars and rank in the 7th and 3rd percentiles. As context, all six report free/reduced lunch eligible for 2024–2025; shares range from 82% at MacArthur to 97% at Willard. Student–teacher ratios range from 14.3 at Willard to 22.4 at MacArthur, observations that do not by themselves explain achievement differences.
