Summary
March Mountain High is a 255-student school serving grades 9–12 in Moreno Valley, part of Moreno Valley Unified. Its latest reported graduation rate is 92%, above California’s 88%, and its dropout rate is 2%, below the state’s 8%. But those outcomes sit alongside a serious attendance and achievement challenge: 55% of students were chronically absent in 2025–26, while math proficiency was 0% and science proficiency was 2%.
ELA is the school’s strongest subject relative to nearby schools, though results remain low: 25% of students were proficient, compared with 35% in the district and 49% statewide; among eight nearby schools with results, March Mountain was above two. Math and science are the sharpest academic concerns: math was 0%, versus 20% in the district and 38% statewide, and was lowest among those eight nearby schools; science was 2%, versus 20% in the district and 36% statewide, and was also below all eight. Attendance is another major concern: the 55% chronic absenteeism rate was 30 percentage points above the district and 37 above the state. Only Val Verde High had a higher rate among the 10 nearby schools.
ELA proficiency has improved over time, rising from 17% in 2022–23 to 25% in 2025–26, while the gap with the state narrowed by 5 points. Math fell from 1% to 0%, and science from 7% to 2%; their state gaps widened. Absenteeism improved from 63% in 2021–22 to 55% in 2025–26, but recently rose from 49% to 55%. SchoolDigger ranks the school 1,878th of 2,137 statewide, at the 12th percentile with 1 star; its percentile rose from 3 in 2021–22 but was only 1 point above the prior year. The 2024–25 student-teacher ratio was 10.2, the lowest among 10 nearby schools, and 83% of students were free/reduced lunch eligible that year. SchoolDigger’s English Language Learner subgroup ranking fell from the 38th percentile in 2022–23 to the 20th in 2023–24, an 18-point drop in this measure of the school’s relative results for that group.
