Summary:
91763 has one listed high school, Montclair High, serving grades 9–12 and enrolling 2,515 students. Its results show a notably different picture by subject: in 2025–2026, 64% of students were proficient in English language arts (ELA), compared with 25% in mathematics. The clearest takeaway is that ELA is a strength relative to the state, while mathematics is the school’s largest academic shortfall.
There is no second school in the list to compare at the top or bottom, so Montclair High is both the highest and lowest school here—but that distinction does not indicate how it compares with other local schools. Against state results, ELA stands out positively: 64% proficient versus 49% statewide, a 15-point advantage. Mathematics is the main concern: 25% versus 38% statewide, 13 points lower. Science was closer to the state result, at 34% versus 36%, or 2 points lower. The school’s graduation rate was 92%, 4 points above the state’s 88%; chronic absenteeism was 20%, 2 points higher than the state’s 18%.
Recent results moved in different directions by subject: from 2024–2025 to 2025–2026, ELA fell by 5 points and mathematics by 5 points, while science rose by 6 points. The ELA lead over the state narrowed from 21 points to 15; the math gap widened from 7 to 13 points below the state, while the science gap narrowed from 5 to 2 points below. SchoolDigger gives Montclair High a 2025–2026 statewide rank of 753 out of 2,137, in the 65th percentile, with 3 stars; its prior rank was 577 out of 2,162, in the 73rd percentile. The student–teacher ratio is 23.5, and 83% of students were free/reduced lunch eligible in 2024–2025. These figures describe the school’s context, not the cause of its results.
