Summary:
The nine high schools in San Bernardino City Unified serve grades 9–12, except San Andreas High, which serves grades 10–12. In 2025–2026, the schools’ average proficiency was below the state average in English language arts (ELA), math and science: 43% versus 49% in ELA, 21% versus 38% in math, and 26% versus 36% in science. The most important finding is that results vary sharply between schools, with Middle College High far ahead of the rest.
Middle College led in all three subjects, with 93% ELA, 64% math and 64% science; its lead over the next-highest school was 28, 34 and 32 percentage points, respectively. It also had a 100% graduation rate and 8% chronic absenteeism. Cajon High was the strongest larger comprehensive school in ELA and math, at 65% and 30%. At the other end, San Andreas had the lowest ELA and math results, 7% and 2%, and 80% chronic absenteeism. Sierra High had the lowest science result, 7%, and the lowest graduation rate, 82%.
Average results improved from 2024–2025 to 2025–2026 by 3 points in ELA, 3 in math and 6 in science, although Pacific High declined in all three subjects. The ELA gain was concentrated at Middle College, up 21 points; without it, the other schools’ average gain was less than 1 point. SchoolDigger gave Middle College five stars and a 97th-percentile ranking. Enrollment or student–teacher ratio alone does not indicate performance: Cajon had 2,748 students and a 24.6:1 ratio, while similarly sized Arroyo Valley High had 2,692 students and a 24.0:1 ratio, but lower proficiency. All schools reported the same low-income measure, free/reduced lunch eligible, for school year 2024–2025; figures ranged from 87% at Cajon to 97% at Indian Springs High and Pacific. These are comparisons between schools, not explanations for their results.
