Summary

Grossmont High is a public school serving 2,172 students in grades 9–12 in La Mesa, within the Grossmont Union High district. Its 2025–26 results show stronger proficiency in English language arts (ELA) and science than in math: 59% in ELA, 40% in science and 30% in math. The most important warning is the sharp grade-level difference in science: 11th-grade proficiency is 42%, but 12th-grade proficiency is just 11%—22 points below the state.

Compared with the state, Grossmont High is ahead in ELA by 9 points and science by 5, but trails by 9 points in math. Compared with its district, it is ahead by 7 points in ELA, 8 in science and 1 in math. It also stands out among nearby schools with reported results: it ranks third in ELA and science and fourth in math. Its results exceed the nearby-school averages by 16 points in ELA, 6 in math and 8 in science. For example, its ELA proficiency is below that of Grossmont Middle College High and Henry High, but above the nearby average.

Over four years, math rose 6 points and science 5, while ELA slipped by 1; the school’s gaps with state results narrowed modestly. SchoolDigger places Grossmont High at the 66th statewide percentile with 3 stars in 2025–26, up 4 percentile points from the prior year but below its 72nd-percentile standing in 2023–24. Its reported 2024–25 student-teacher ratio is 24.3, and 64% of students were free/reduced lunch eligible that year, close to the nearby-school average of 65%. One notable difference in SchoolDigger’s group rankings is that its ranking for how well it serves Asian students is at the 3rd percentile, far below its overall 66th-percentile ranking.
