Summary:
Brea Junior High is the only middle school listed in Brea-Olinda Unified, serving grades 7–8 with 921 students (enrollment reported for 2024–2025). Its 2025–2026 results put it well above California in every tested subject: by 20 percentage points in English language arts (ELA), 23 points in math and 17 points in science.
With just one school in the list, there is no separate top- and bottom-performing school; Brea Junior High is both the only option and the clear standout against state results. Its proficiency rates were 69% in ELA, 61% in math and 53% in science, compared with California’s 49%, 38% and 36%, respectively. The school’s strongest results relative to the state were in ELA, while math had the largest percentage-point advantage. Within the school, grade 7 rates were higher than grade 8 by 7 points in ELA and 5 points in math. SchoolDigger rated the school four stars and placed it in the 89th percentile in 2025–2026, rank 299 of 2,703 schools.
Results over time show a steady state advantage, though the gap narrowed in math and science. From 2024–2025 to 2025–2026, ELA rose by less than a point and its state gap stayed about 20 points; math fell by 1 point as the state rate rose, narrowing the gap by 2 points; science rose by less than a point while the state rose by 3 points, narrowing the gap by 3 points. SchoolDigger’s percentile was 88th in 2023–2024 and 90th in 2024–2025 before reaching 89th. Other context: the student-teacher ratio was 20.2 in 2024–2025, and 38% of students were free/reduced lunch eligible that year. In 2025–2026, chronic absenteeism was 10% at the school, below California’s 18% but above the district’s 9%. Because this list includes only one school, it cannot show how schools in the area compare with one another.
