Summit High serves 2,725 students in grades 9–12 in Fontana, within Fontana Unified. Its graduation and dropout outcomes are especially strong: in 2025–2026, 97.8% of students graduated, compared with 95.6% in the district and 87.9% statewide; only nearby Wilmer Amina Carter High was higher, at 98.1%. Summit’s dropout rate was 0.3%, the lowest reported among nearby schools, versus 1.9% in the district and 8.3% statewide.

ELA is Summit’s strongest subject compared with nearby schools, while science is its weakest. In 2025–2026, 69% of Summit students were proficient in ELA, above the state’s 49% and district’s 41%; Summit ranked fourth among eight nearby comprehensive high schools, just above their 68% average. Math proficiency was 36%, slightly below the state’s 34%? Wait, the state result was 38%, making Summit 2 points lower; it was 10 points above the district and just above the nearby-school average of 35%. Science proficiency was 34%, 2 points below the state and 9 above the district, but 7 below the nearby-school average of 40%; Summit ranked sixth of eight. This makes science the clearest academic area to watch, especially against local peers.
