Summary:
Zip code 91906 has one listed school, Campo Elementary, serving grades K–6 and enrolling 359 students. In 2025–2026, its all-grade proficiency was below California’s in ELA, math and science: 25% versus 49% in ELA, 17% versus 38% in math, and 11% versus 36% in science. Its simple average across the three subjects was 17%, compared with 41% statewide. The most important finding is that the school’s results are substantially below state levels in all three subjects.
There is no meaningful top-to-bottom school comparison because Campo is the only school in the list. Within the school, third grade stands out: ELA proficiency was essentially level with the state, at 44% versus 44%, and math was 42%, 5 percentage points below the state’s 47%. The higher tested grades had much larger gaps: in grade 6, ELA was 12% versus 48% statewide, and math was 3% versus 37%. Across all grades, science is the weakest relative subject, with Campo 25 points below the state; math has the smallest state gap, at 22 points, but remains well below the state result. Campo’s all-grade scores were close to those in Mountain Empire Unified, within 2 points in each subject.
Recent results show a mixed picture at Campo but a widening overall gap with the state. From 2024–2025 to 2025–2026, ELA was unchanged, math rose 2 percentage points, and science fell 9 points; the state’s results rose in all three subjects, including a 3-point increase in science. SchoolDigger ranked Campo 5,007th of 5,804 schools in 2025–2026, at the 14th percentile with 1 star; its listed results for the two preceding years were also at the 14th percentile with 1 star. Other context includes a student-teacher ratio of 22.1 in 2024–2025 and 47% free/reduced lunch eligible that year. These measures provide context, not an explanation for test results.
