Summary
Westwood Elementary is a K–5 school in Concord, California, serving 224 students in the Mt. Diablo Unified area. Its 2025–2026 test results were below district and state averages in English language arts (ELA), math, and science. The clearest concern is math, especially in third and fifth grades: 28% of students were proficient overall, including 24% in third grade and 22% in fifth.
Compared with nearby K–5 schools, ELA is Westwood’s strongest subject: its 41% all-grades result was about 5 percentage points above the nearby-peer average, ranking third among eight schools with comparable data. Math and science were lower in that group, ranking sixth in each subject; proficiency was 28% in math and 27% in science, versus peer averages of 33% and 28%. Grade-level results tell a more varied story: fourth-grade ELA was 47%, slightly above the district’s 47% and state’s 46%, while third-grade ELA was 28%, 17 points below the state. Fourth-grade math reached 39%, compared with 24% in third grade and 22% in fifth.
Results have improved overall since 2022–2023, but recent scores remain below earlier peaks: ELA rose from 33% to 41%, math from 25% to 28%, and science from 6% to 27%; all three peaked in 2023–2024 before declining. Westwood is at the 39th statewide percentile with 2 stars in SchoolDigger’s 2025–2026 rankings, compared with the district’s 49th percentile and 2 stars. Its 2024–2025 student-teacher ratio was 20.3, the lowest among nearby K–5 schools. The school reported that 72% of students were free/reduced lunch eligible in 2024–2025, higher than six and lower than three of nine nearby schools reporting that measure. With 224 students, it is also smaller than nearby K–5 schools, so individual-grade results can be less stable.
