SchoolDigger Rank ?

of 2,703 California Middle Schools

Better than 7% of California middle schools

Summary

Oak Grove Middle serves 681 students in grades 6–8 in Concord, within Mt. Diablo Unified. Its 2025–2026 proficiency results were low across all three tested subjects: 23% in English language arts (ELA), 10% in math and 9% in science. The clearest finding for families is that Oak Grove scored below every nearby school in all three subjects.

ELA is Oak Grove’s strongest subject relative to nearby schools, while math is weakest against state, district and local comparisons. Nearby schools averaged 63% in ELA, 52% in math and 48% in science, putting Oak Grove 39, 42 and 40 percentage points below those averages, respectively. Its ELA result was also 26 points below the state and 25 below the district; math was 29 points below both; science was 27 points below the state and 26 below the district. Attendance is another concern: chronic absenteeism was 28% in 2025–2026, above the district’s 19% and the state’s 18%, and higher than the rate at any nearby school.

Scores have risen since 2022–2023, gaining 6 points in ELA, 1 in math and 5 in science, but the state gap narrowed only in ELA over that span; math and science gaps widened. SchoolDigger ranked Oak Grove 2,519th of 2,703 statewide schools in 2025–2026, at the 7th percentile with 0 stars. Its 20.6 student-teacher ratio in 2024–2025 was the second-lowest among nearby schools, while 88% of students were reported as free/reduced lunch eligible that year, the highest nearby rate. One subgroup ranking stands out: SchoolDigger placed Special Education Students at the 16th percentile in 2025–2026, up from the 4th percentile the year before, though the current statewide ranking remains low.
