Summary
Mt. Pleasant High is a 998-student high school serving grades 9–12 in San Jose’s East Side Union High district. Its results show a mixed picture: graduation is above state and district rates, while academic proficiency varies sharply by subject. The clearest concern is math and science: proficiency in both is well below state and district results, even though English language arts (ELA) is close to the state level.
ELA is the school’s strongest subject relative to benchmarks, and math is its weakest. In 2025–2026, ELA proficiency was 50%, compared with 49% statewide and 61% in the district; math was 17%, versus 38% statewide and 37% in the district. Science proficiency was 22%, compared with 36% statewide and 42% in the district. Locally, among nearby grades 9–12 schools with results, the averages were 58% in ELA, 37% in math and 34% in science, placing Mt. Pleasant below those averages in all three subjects. Graduation was 90%, above the state’s 88% and district’s 81%; dropout was 7%, below the state’s 8% and district’s 14%. Chronic absenteeism, however, was 22%, four points above the state rate.
Results over time are mixed: since 2022–2023, ELA proficiency fell 6 points, while math rose 3 and science rose 2; state gains outpaced the school’s math and science improvement. SchoolDigger placed the school at the 40th percentile with 2 stars in 2025–2026, down from the 65th percentile in 2018–2019, though it edged up from 39 the prior year. The student-teacher ratio was 20.8 in 2024–2025. Free/reduced lunch eligible students made up 63% in 2024–2025, a measure of the school’s context, not an explanation for its results. SchoolDigger’s statewide ranking for English Language Learner Students was notably higher than the school’s overall ranking in 2023–2024: the group ranked at the 93rd percentile versus 46th overall. For Asian Students, the 2025–2026 ranking was notably lower: the 18th percentile versus 40th overall.
