The top reported proficiency rate is 41% in English language arts. The lowest is 27% in Science.
Original Research by School Decision on Westwood Elementary
Westwood Elementary sits on West Street in Concord, a large, commercially active city that anchors central Contra Costa County. The school serves kindergarten through fifth grade within Mt. Diablo Unified, one of the larger districts in the region.
The student body is moderately sized for a K-5 school in California. It is racially and ethnically diverse: Hispanic students make up the largest share, followed by white students, then students of two or more races, and Asian students. Close to half of students qualify for free or reduced-price lunch, a meaningful indicator of economic need in the community. Data on English learners and students with IEPs were not available in the information provided, so families with those interests would want to ask the school directly about its support services.
On California's CAASPP state assessments, Westwood's tested grades show proficiency rates in English language arts that run roughly in the range of the upper thirties to the upper forties across grades three through five, with third grade performing somewhat better than the older grades. Math results are lower across the board, with fifth grade trailing notably behind the others. Fifth-grade science results on the CAST sit in a similar range to the math scores. Taken together, these figures place the school below the midpoint among the districts in Contra Costa County on the composite proficiency measure used in that comparison. That framing is relative to districts, not individual schools, so families should keep in mind the school sits within a county with some high-performing outliers that pull the midpoint up. State trend data covers only the most recent year, so there is no multi-year picture available to assess whether scores are rising, falling, or holding steady. A parent who wants to understand what the school is doing to improve in math in particular would be reasonable to raise that question with the principal.
Program information was not included in the data provided, so a full picture of enrichment, intervention, after-school offerings, or how the district's new Proposition 28 arts funding is being applied at the school level is not available here. Publicly reported information indicates Mt. Diablo Unified adopted a Strategic Arts Plan through 2028 tied to that state funding, with expanded arts and music instruction beginning in the 2023-24 school year, though how that investment reaches each individual school is worth confirming directly.
Because Westwood goes only through fifth grade, graduation rate and high school pathway data do not apply here, as those measures are simply not relevant to this grade band.
For families thinking about the broader community, Concord is a genuinely diverse, mid-sized Bay Area city with a real civic core. Todos Santos Plaza downtown hosts a year-round farmers market, summer concerts, and regular food trucks, and the city maintains a substantial parks system with open space trails nearby. Two BART stations give the city real transit reach into the broader Bay Area. The biggest long-term change on the horizon is the planned redevelopment of the former Concord Naval Weapons Station on the city's northeast side, a very large mixed-use project approved in principle in 2026, though public reporting suggests infrastructure construction is unlikely to begin before 2030 and that first housing is still years beyond that.
Housing near the school is priced well above the California statewide median, and rents are also elevated. The mortgage-to-rent gap is wide, meaning ownership carries a substantially higher monthly cost than renting at current rates, which is relevant context for families deciding whether to buy in the attendance area. Home values in the zip code have dipped slightly year over year while rents have risen modestly.
