Summary:

Brentwood Union has 12 schools serving kindergarten through grade 8: nine elementary schools serving K–5 and three middle schools serving grades 6–8. They enroll 9,932 students, averaging 828 per school; middle schools average 1,156 students and elementary schools 718. Across schools, average proficiency is above the state figure in ELA, math and science, but individual results vary substantially. The most important takeaway is that the district-wide averages do not describe every school: a child’s results depend meaningfully on the school and subject.

Adams (J. Douglas) Middle is the strongest all-around standout: it leads ELA at 69% and science at 52%, and is second in math at 55%; its scores are 19, 16 and 16 percentage points above state results, respectively. Isaac R. Montanez Elementary leads math at 56%, 17 points above the state. R. Paul Krey Elementary is above the state in all three subjects and leads elementary schools in science at 48%. At the lower end, Marsh Creek Elementary has the lowest ELA result, 42%, or 7 points below the state; William B. Bristow Middle has the lowest math result, 34%, 5 points below; and Brentwood Elementary has the lowest science result, 32%, 4 points below.

Compared with the prior year, school averages fell by 2 points in both ELA and math but rose by 1 point in science; the schools’ average lead over the state narrowed in all three subjects. Individual changes differ: Loma Vista Elementary had the largest ELA drop, 9 points, while science rose by 8 points; Mary Casey Black Elementary gained 12 percentile points in SchoolDigger’s three-year statewide ranking, while Marsh Creek fell 17. Student-teacher ratios range from 21.8 at Edna Hill Middle to 26.3 at Pioneer Elementary, but neither ratio identifies the academic leaders. For school year 2024–2025, reported directly certified for free meals rates include 16% at Loma Vista and 25% at Edna Hill; free/reduced lunch eligible rates include 42% at Garin Elementary and 52% at Marsh Creek, and these are different measures that should not be compared directly.
