Summary

Ellerhorst Elementary is a K–6 school in Pinole, serving 319 students in West Contra Costa Unified. Its 2025–2026 all-grades results were above the district in English language arts (ELA), math and science. The main takeaway for families is that math is a clear strength, while science is the school’s most important academic concern.

Compared with nearby schools, math is Ellerhorst’s strongest subject: 46% of students were proficient, 9 percentage points above the nearby-school average and third among the ten schools. ELA was also above the nearby average—50% versus 44%—and just above California’s 49%; it ranked fourth locally. Science was weaker: 26% proficient, 7 points below the nearby average and 10 below the state, though 2 points above the district. Results also vary by grade: fourth-grade math was the highest among the ten schools at 64%, while fifth-grade ELA was 31%, 18 points below the state and the second-lowest local result.

Results have improved since 2022–2023: ELA rose 14 percentage points to 50%, math rose 11 points to 46%, and science rose 8 points to 26%. But science fell 14 points from its 2024–2025 result of 40%. SchoolDigger ranked Ellerhorst in the 62nd percentile statewide, with 3 stars, tying Olinda Elementary; it trailed Ohlone Elementary (84th percentile) and West County Mandarin (83rd). Its student-teacher ratio was 19.9 in 2024–2025, below the nearby average of 21.4. In that same year, 59% of students were free/reduced lunch eligible, compared with a nearby average of 53%; these are contextual measures, not explanations for achievement. SchoolDigger’s group-specific rankings were notably higher for White Students (83rd percentile) than for the school overall (62nd); its Female Students ranking rose from the 56th percentile in 2023–2024 to the 73rd in 2025–2026.

What people are saying

by a parent
Saturday, August 18, 2018

Ellerhorst is a hidden gem in WCCUSD, and its quality is belied by the test scores. There are a number of factors that affect the overall test scores (like EL population and 3 self contained special ed classrooms) but that don't effect the overall quality of education. The kindergarten classrooms this year only have 17 kids per class! There is incredible parent involvement, with at least one parent a day volunteering in every primary class. The classes go on numerous field trips a year, and there's an awesome after school program including many enrichment classes like chess and cooking. It's a gorgeous campus and feels more like a private school than a public school in a low ranked district. Close Quote
