The top reported proficiency rate is 40% in English language arts. The lowest is 27% in Science.
Original Research by School Decision on Crestmore Elementary
Crestmore Elementary sits on Jurupa Avenue in Bloomington, an unincorporated community in the western Inland Empire wedged between Colton, Rialto, and Fontana. It serves kindergarten through sixth grade as a regular public school within Colton Joint Unified, and its student body is overwhelmingly Hispanic, with nearly all students qualifying for free or reduced-price lunch. Those two facts together tell you a great deal about the community this school serves: a working-class, predominantly Latino neighborhood where household budgets are tight and the school is a central institution.
On California's statewide CAASPP assessments, Crestmore's results are below the state midpoint. In English language arts, third graders perform closest to average for the school, while fourth and fifth graders score noticeably lower; sixth graders land somewhere in between. Math results are weaker still across all tested grades, with third grade being the relative high point and the upper elementary grades sitting considerably below the state average. Science, tested at fifth grade on the CAST, comes in below the midpoint as well. When the school's overall proficiency index is placed among districts in San Bernardino County, it lands above the midpoint of that set, which is worth noting given how competitive the county's range is, though that positioning should be read alongside the actual proficiency levels rather than in place of them. Trend data covers only a single year, so there is no multi-year trajectory available to show whether scores are improving or holding steady. A parent who wants to understand direction would be well served by asking the school directly about year-over-year progress.
Data on chronic absenteeism and IEP or English learner rates was not available in the records, which are gaps worth raising with the school. Those populations are common in a community like Bloomington, and understanding how the school supports them matters for any family whose child might benefit from those services.
Bloomington itself is a place in active tension. Publicly reported accounts describe a community that has long offered affordability uncommon in coastal California, and home values in the area, while above the national midpoint, sit well below the California state average. For families priced out of incorporated cities nearby, Bloomington has been a realistic entry point into homeownership. The built environment is a patchwork: mid-century ranch homes on large lots where some residents still keep horses, newer subdivisions, mobile home parks, and an industrial corridor along Interstate 10 that has grown substantially. A major warehouse development approved by the county in 2022 has reshaped parts of the community, with scores of homes demolished for the project; as of mid-2026, publicly reported litigation over that development's environmental review was still active. The county has also invested in civic infrastructure, including a rebuilt Ayala Park that opened in 2022 and the Bloomington Branch Library, built alongside affordable housing on county land.
For Colton Joint Unified as a whole, voters approved a school facilities bond in November 2024, the district's first new bond authorization in decades. The measure funds repairs and modernization at aging campuses and carries a property-tax levy for homeowners for as long as the bonds are outstanding. For a family buying in Bloomington, that represents both a long-term cost and, if the investment is well managed, an eventual improvement in school facilities.
Crestmore is a neighborhood school serving a high-need community where academic proficiency rates are lower than the state would want them to be. That is worth naming plainly, and parents who prioritize academic outcomes should ask the school what support structures are in place, what supplemental instruction looks like, and how the school is working to move those numbers. At the same time, the school serves children in one of the more affordable corners of a very expensive state, and understanding what it offers in terms of stability, culture, and day-to-day support requires a visit and direct conversation rather than test scores alone.
