Orchard Park, Oakley CA - Test Scores & Data

Original Research by School Decision on Orchard Park

Orchard Park is a neighborhood school serving kindergarten through eighth grade in Oakley, a young, rapidly growing suburb in East Contra Costa County with a strong agricultural and family-oriented character. The school draws from a diverse student body, with a substantial share of students qualifying for free or reduced-price lunch, and serves a community that is predominantly Hispanic, with meaningful populations of Black, Asian, and white residents.

The school's academic performance reveals a mixed picture that warrants close parental attention. English language arts shows relative strength in the upper middle grades, particularly in grade seven and eight, where proficiency rates rise notably above the earlier grades. Math proficiency is notably lower across all tested grades, remaining well below typical state performance benchmarks in the lower elementary grades and improving only modestly in grade six before declining again in the upper grades. Science proficiency at the fifth-grade level is quite low, though eighth-grade science results are substantially higher, suggesting differential classroom support or student readiness across the grade span. Overall, Orchard Park's proficiency index places it below the midpoint among districts in Contra Costa County, indicating that academic achievement here is an area families should explore directly with the school about their approaches and support systems.

The school's position in Oakley reflects both the city's character and its growth. Oakley is one of California's younger incorporated cities, organized around a deliberately developed downtown Main Street with civic amenities, but with residential life spread across new suburban neighborhoods and surviving farmland. Housing values in the area are substantial, above state averages, and rents are rising; the affordability picture shows rent consuming a notable share of household income. The city is experiencing strong population growth, with significant new residential construction concentrated in planned communities and development corridors, meaning the school likely draws from both established families and newer residents moving into the area.

Orchard Park's parent district, Antioch Unified, is facing material fiscal challenges that any family considering the school should understand. The district underwent a serious budget crisis in 2026, authorizing layoffs affecting teachers, paraeducators who support special education, custodians, and school psychologists. The county downgraded the district's budget certification to negative status, a significant warning indicator that suggests the district may struggle to meet financial obligations without substantial changes. The district also passed Measure B, a school facilities bond in 2024 that added a long-term property tax obligation affecting homeowners in the district. Additionally, the district is discussing a potential parcel tax. These fiscal pressures mean families should expect ongoing uncertainty about staffing and service levels while also facing increased property tax obligations.

The school itself sits on a separate campus rather than in downtown Oakley; the district maintains multiple elementary and middle schools across the area. Kindergarten enrollment and each tested grade band are represented, creating a full K-8 pathway within the school. A parent considering Orchard Park would want to ask the school directly about the impact of district layoffs on classroom staffing, how the school is addressing the math proficiency gap, and what support systems exist for students scoring below proficiency, particularly in the elementary grades where the gap is widest.

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.
