Elementary Schools in West Contra Costa Unified

The 37 elementary schools in West Contra Costa Unified serve students in K–5, K–6, and K–8 grades. In 2025–26, their unweighted average proficiency was 31% in English language arts (ELA), 27% in math, and 23% in science, compared with state rates of 49%, 38%, and 36%. The most important finding is that results vary sharply from school to school, while the group averages fall below the state in all three subjects.

Madera led in every subject, with 79% proficiency in ELA, 73% in math, and 74% in science—about 30, 35, and 38 points above the state rates. Kensington also performed strongly, at 73% in ELA, 69% in math, and 65% in science; Ohlone stood out in math and science, at 66% and 53%. At the low end, Lincoln had the lowest ELA result, 6%—44 points below the state. Martin Luther King Junior and Ford tied for the lowest math result at 5%, while Cesar E. Chavez had 0% proficiency in science.

Group averages rose from 2024–25 to 2025–26, but by less than one point in ELA and math and by 2 points in science; state rates rose slightly more in ELA and more in math and science. SchoolDigger’s 2025–26 statewide percentiles place Madera at the 94th, Kensington at the 90th, and Ohlone at the 84th; movement over time differs, with Washington rising from the 19th to the 26th percentile and Shannon falling from the 54th to the 22nd. The free/reduced lunch eligible measure for 2024–25 was 13% at Madera and 14% at Kensington, but results do not follow a simple pattern: Fairmont, at 53%, had 46% ELA proficiency, while Hanna Ranch, at 40%, had 50%. These figures are context, not explanations; schools also serve different grade spans, so comparisons are not perfectly like-for-like.
