O'hara Park Middle, Oakley CA - Test Scores & Data

Original Research by School Decision on O'hara Park Middle

O'Hara Park Middle serves grades six through eight in Oakley, a rapidly growing suburb in East Contra Costa County. The school enrolls students of mixed socioeconomic backgrounds; a substantial share qualify for free or reduced-price lunch. The student body is predominantly Hispanic, with smaller populations of white, Asian, Black, and other students represented. Enrollment across the grade bands is relatively balanced, with the school sitting in the low to mid-range for size among its county's middle schools.

State test results from the 2024-25 school year show the school facing significant academic headwinds. In English language arts, proficiency ranges from near-low to moderate across the grade levels, with sixth grade performing better than grades seven and eight. Mathematics proficiency is markedly weak across all three grades, with each grade level showing particularly low results. A science assessment for eighth grade showed similarly low proficiency. The most recent comparable data point available is a single-year social studies result from 2012-13, which is too distant to inform a current picture. When proficiency rates across all tested subjects and grade levels are averaged together, the school's overall academic performance sits below the midpoint among the county's districts that reported comparable data.

The lack of multiyear trend data means it is not possible to tell whether results are improving, flat, or declining. Families may want to ask the school directly about recent progress and any instructional changes underway, as the data available does not illuminate trajectory.

Oakley itself is one of California's youngest incorporated cities, situated on the California Delta in East Contra Costa County and marketed as a family-oriented suburb with small-town character. The area is in the midst of sustained growth, with hundreds of acres zoned for new housing and commercial development, particularly along the East Cypress Corridor. The city has invested in downtown infrastructure including a Civic Center and Main Street improvements aimed at walkability, though the broader community remains car-dependent. Housing prices in the area have been cooling slightly year-over-year. The cost of a mortgage is estimated at a substantial portion of typical household income, though rents run lower and are described as more affordable relative to that income benchmark.

The Oakley Union Elementary School District, of which O'Hara Park Middle is a part, passed a major facilities bond (Measure K) in June 2026 to repair aging infrastructure including roofs, plumbing, electrical and HVAC systems across its schools. This represents a sustained property-tax commitment to modernize district buildings. However, a companion measure focused on school safety and security improvements failed. The district has also faced budget strain, moving to reduce staff positions to balance finances, a factor that can affect class sizes and program stability. The oldest schools in the district date back decades, making facility renewal a real need.

The combination of low state testing proficiency, limited available trend data, and the district's budget and facility challenges creates an environment where engaged parent oversight would be particularly valuable. A family considering this school would want to understand what supports and instruction are in place for struggling readers and mathematicians, how the school is using its state assessment results to drive change, and how the district's financial situation is affecting teaching resources and class composition.

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.
