Better than 4% of California high schools

Summary

Apollo High is a small, 88-student school serving grades 9–12 in Simi Valley, in the same area as several nearby high schools. Its reported chronic absenteeism rate is exceptionally high: 65% in 2025–26, compared with 18% statewide and 16% in Simi Valley Unified. The most pressing academic finding is that Apollo’s test proficiency was below the state, district and lowest reported nearby result in all three tested subjects.

Among its test results, science is the least far behind those comparison groups, while English Language Arts/Literacy (ELA) is the greatest weakness. In 2025–26, Apollo’s proficiency was 8% in ELA, 0% in math and 4% in science; its results were 41, 38 and 32 percentage points below the state, respectively, and 42, 37 and 36 points below the district. The lowest reported nearby results were at Simi Valley High: 57% in ELA, 34% in math and 38% in science. Graduation is a relative bright spot over time, reaching 84% in 2025–26, though that remained below the state’s 88% and the district’s 94%.

Test results have not kept pace with statewide improvement: from 2022–23 to 2025–26, Apollo’s state gap widened by 2 percentage points in ELA, 5 in math and 13 in science. SchoolDigger placed Apollo at the 4th percentile with 0 stars in 2025–26, the lowest rank among nearby schools ranked that year; its percentile fell from 13 in 2022–23. Context includes a student-teacher ratio of 7.3 in 2024–25, the lowest among nearby schools with reported figures, and a free/reduced lunch eligible share of 80% that year, the highest among nearby schools with the same measure and year. One notable SchoolDigger subgroup result was a 91st-percentile ranking for English Language Learner Students in 2021–22, compared with 18 overall; the subgroup ranking fell to 13 the following year. Oak View High’s test results are suppressed, so they cannot be included in score comparisons.
