Ramona Middle, San Dimas CA - Test Scores & Data

Original Research by School Decision on Ramona Middle

Ramona Middle sits on Ramona Avenue in San Dimas, a foothill suburb in the eastern San Gabriel Valley where the San Gabriel Mountains serve as a backdrop to a mix of horse properties, residential neighborhoods, and a walkable Western-themed downtown along Bonita Avenue. The school serves sixth through eighth grade as a regular public school in the Bonita Unified School District.

On California's CAASPP assessments, Ramona students score well above the statewide midpoint. In English language arts, proficiency rates across all three grade levels run from the low seventies into the upper seventies, with seventh grade performing strongest. Math proficiency follows a slightly different arc: sixth and eighth grade students score in the upper sixties, while seventh grade dips closer to the high fifties. Science results, reported for eighth grade only via the California Science Test, land in the upper fifties. Taken together, the school's overall proficiency index places it in the top quartile relative to districts across Los Angeles County, a strong position in a county with more than four hundred school districts. Trend data across multiple years was not available; only the most recent year is reported, so there is no trajectory to describe.

The enrollment is substantial for a three-grade middle school and is racially and ethnically diverse. Hispanic students make up the plurality, followed by white students, then multiracial and Asian students, with smaller Black and Pacific Islander populations. About a third of students qualify for free or reduced-price lunch, meaning a meaningful share of families meet income eligibility thresholds, though the school does not carry a Title I designation in the available data. Data on English learner rates and special education rates were not reported in the source material, so a parent wanting detail on those supports should ask the school directly. Discipline data, chronic absenteeism figures, and staffing information were also absent.

The Bonita Unified district has two publicly reported parent-relevant developments. First, the Board placed a facilities bond measure on the June 2026 ballot, tied to a long list of identified repairs and upgrades across all school sites. Passage would carry an annual cost to property owners per unit of assessed value for the life of the bonds and would position the district to pursue state matching funds; existing bonds from earlier cycles are still on tax bills. Second, the district is rolling out an ethnic studies curriculum beginning in the 2025-2026 school year, following a two-year adoption process that included parent input and aligns with a California state graduation requirement taking effect in 2030.

San Dimas itself is a place in transition. The historic downtown on Bonita Avenue is genuinely walkable, with independent shops, breakfast spots, and antique storefronts clustered around City Hall. Outside that core the city is car-dependent, with chain retail along State Route 57 and freeway access via the 10 and the 57. The bigger change is the arrival of Metro passenger service on the Foothill Gold Line extension in 2025, which added a San Dimas station. The city has been planning transit-oriented housing and mixed-use development around that station, with its housing element requiring sites for new homes, a portion of them affordable. Families buying into this market should be aware that home values here run well above the California statewide benchmark, which itself runs well above the national figure, and typical rents consume a substantial share of the median household income. Year-over-year home value growth has been modest, and rent growth nearly flat.

Program offerings specific to Ramona Middle were not available in the data provided, so the academic pathway beyond test performance is a gap a parent would want to explore with the school.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
