Summary
Sierra Vista Charter High is a 166-student charter school serving grades 9–12 in Tulare, in the Tulare Joint Union High district. Its reported graduation rate is high: 97% in 2025–2026, compared with 88% statewide and 98% in the district. Attendance is a concern, however: chronic absenteeism is 30%, versus 18% statewide and 15% in the district. The most important finding is that test proficiency is low in all three subjects, despite the strong graduation rate.
Science is the school’s strongest subject relative to the state, district and nearby schools, while math is its weakest compared with the state. In 2025–2026, proficiency was 18% in ELA, 0% in math and 14% in science—below state results by 31, 38 and 22 percentage points, respectively, and below district results by 38, 24 and 15 points. Among nearby 9–12 schools with results, the average was 52% in ELA, 24% in math and 32% in science; Sierra Vista fell short of those averages by 34, 24 and 18 points. It ranked third-lowest among those schools in ELA and science, and fourth-lowest in math.
Results have been uneven over time: ELA fell 23 points from 2024–2025 to 2025–2026, while science rose 3 points in the latest year after an overall decline since 2022–2023; math was 0% at both endpoints. SchoolDigger ranks the school 1,767th of 2,137 statewide, at the 17th percentile and one star; its percentile dropped 16 points since 2021–2022. Its 14.9:1 student-teacher ratio is among the lower ratios nearby, but has not coincided with stronger proficiency. The school reports 80% free/reduced lunch eligible for school year 2024–2025; this is an eligibility measure, not a count of students receiving meals. SchoolDigger’s measure of how well the school serves English Language Learner Students was at the 3rd percentile in 2022–2023, versus the school’s overall 32nd percentile. For Female Students, that measure fell from the 30th percentile in 2023–2024 to the 10th in 2025–2026.
