Summary:
Campbell Union High includes six high schools, all serving grades 9–12. In 2025–2026, their average proficiency was 59% in ELA, 39% in math and 43% in science, compared with state results of 49%, 38% and 36%. The group was strongest relative to the state in ELA, averaging 10 percentage points above it, and was nearly level in math, just 1 point above. The most important finding is how uneven the schools are: the gaps between the highest and lowest school scores reach 60 points in ELA, 63 in math and 50 in science, so group averages hide very different school experiences.
Leigh High leads the group, with 78% proficient in ELA, 66% in math and 58% in science—28, 28 and 22 points above state results. Boynton High is lowest in all three subjects, at 17%, 3% and 8%, respectively, and trails the state by 32, 35 and 28 points. Boynton also has the highest chronic absenteeism, 71%, compared with 13% districtwide and 18% statewide. Its 91% graduation rate is above the state’s 88%, though below the district rate of 96%. Westmont High stands out for attendance: its 7% chronic absenteeism is the group’s lowest.
From 2024–2025 to 2025–2026, the six-school average rose 1 percentage point in ELA and 3 in science, but fell 1 point in math. Science proficiency increased at every school, with Westmont’s 6-point gain the largest; math improved only at Leigh and Westmont. SchoolDigger ranks Leigh 161st of 2,137 statewide, in the 92nd percentile with five stars, while Boynton ranks 1,857th, in the 13th percentile with one star. Boynton is also a size and ratio exception: it enrolls 163 students and has a 10.9 student–teacher ratio, while the other schools enroll 1,350–1,884 students and have ratios of 20.5–24.3. Reported free/reduced lunch eligible (FRL) shares for sy 2024–2025 range from 18% at Leigh to 70% at Del Mar; these figures provide context, not an explanation for school results.
