Original Research by School Decision on Bloomington High
Bloomington High is a comprehensive four-year public high school in an unincorporated San Bernardino County community that is experiencing rapid growth and development pressure. The school serves a student body that is almost entirely Hispanic and almost entirely economically disadvantaged, reflecting the demographics of Bloomington itself, an affordable unincorporated area on the fringe of the Inland Empire's logistics hub.
The most recent state assessment data, from spring 2025, shows proficiency rates that are significantly below state benchmarks across all tested subjects. English language arts proficiency stands at roughly two in five students, while proficiency in mathematics and science each fall well below one in five students. Only a single year of data is available, so trajectory over time cannot be assessed. A parent may want to look into further detail with the school about where these results rank relative to peer schools in San Bernardino County, and whether the school has identified specific strategies to address performance gaps.
The school's enrollment is stable across grades, with a balanced distribution of about four hundred-plus students per grade level. A substantial share of students qualify for free or reduced-price lunch, reflecting family income levels in the community. The school's racial and ethnic composition is heavily concentrated; Asian, Black, White, and multiracial enrollment each make up single-digit percentages. English learner and special education enrollment data were not available.
Bloomington itself is a place of contrasts. The built environment mixes rural housing on large lots, where residents historically kept horses and other animals, with newer single-family subdivisions and a handful of apartment complexes and mobile home parks. Industrial development is reshaping the landscape: major warehouse and logistics facilities operated by Amazon, FedEx, and other companies now dominate along Interstate 10 and Cactus Avenue, reflecting the Inland Empire's dominance in national distribution and warehousing. Retail and dining are concentrated along Valley Boulevard and Cedar Avenue. Housing in the Bloomington zip code remains notably affordable relative to California and the nation, a key draw for working families, though new development and logistics growth are intensifying competition for land and raising long-term questions about the community's residential character.
Bloomington is experiencing rapid change. The county approved a major warehouse development project in 2022 that would bring multiple large fulfillment centers to the area; construction was halted by court order in May 2024 over environmental review flaws, and litigation was ongoing as of mid-2026. On the housing side, the county has invested in mixed-income developments including the Bloomington Grove and Lillian Court projects, which bundle affordable senior and family housing with a new branch library. Transit access is provided by Omnitrans, including the OmniRide Bloomington on-demand microtransit service launched in 2022, alongside fixed bus routes; Metrolink rail access is available a short distance away in Rialto.
At the district level, Colton Joint Unified, which serves all of Bloomington, passed a major school facilities bond in November 2024, the first new bond authorization in over a decade. The measure funds repairs and modernization of aging schools across the district and carries a lasting property tax cost for homeowners. Many schools in the district were built more than five decades ago and require substantial work on roofing, plumbing, electrical systems, and removal of environmental hazards. This reflects the long timeline between major capital investment cycles and carries real implications for facility conditions during the bond-funded improvement period.
Graduation rate data, chronic absenteeism rates, and multi-year proficiency trends were not available for comparison within the county district universe. Course offerings and detailed program information were not provided in available sources. Parents seeking fuller detail on academic pathways, AP availability, career and technical education options, and support services are encouraged to contact the school directly.
