Summary
Oak Grove High is a San Jose public high school serving grades 9–12 in the East Side Union High district, with 1,374 students. Its latest results show a mixed picture beyond academics: chronic absenteeism is 30%, above the state’s 18% and the district’s 24%, while graduation is 85%, below the state’s 88% but above the district’s 81%. The clearest takeaway is that ELA is above the state, while mathematics is substantially below it.
Compared with nearby schools, Oak Grove is relatively strong but not close to the top local performers. It ranked third among nine nearby schools with 2025–2026 results in ELA, math and science. ELA proficiency was 54%, 5 points above the state but 6 below the district. Math was 27%, 12 points below the state and 10 below the district; science was 33%, 3 below the state and 10 below the district. By comparison, Leland High had 80% ELA, 71% math and 67% science proficiency. The school’s 12th-grade science result also stands out: 9% proficient, 24 points below its 11th-grade result, though third-highest among six nearby schools with reported results.
Scores improved from 2024–2025 to 2025–2026 in all three subjects: ELA rose 5 points, math 4 and science 5. Over the longer period since 2022–2023, however, ELA fell 8 points and science fell 2, while math rose 3; science also shifted from 4 points above the state to 3 below. SchoolDigger places Oak Grove at the 57th percentile statewide, with 3 stars. Its student-teacher ratio was 22.1 in 2024–2025, compared with a nearby-school average of 19.4, and 56% of students were free/reduced lunch eligible that year. One notable SchoolDigger subgroup ranking change: Special Education Students rose from the 16th percentile in 2024–2025 to the 56th in 2025–2026, while the overall ranking moved from the 52nd to the 57th percentile. These subgroup percentiles are statewide comparative rankings, not direct measures of individual student progress.
