Summary
Sierra Vista High (Alternative) is a 284-student grades 9–12 school in Whittier, in the Whittier Union High district. The district is rated at the 69th percentile statewide by SchoolDigger, while Sierra Vista’s latest statewide ranking is at the 21st percentile. The most important concern is that proficiency is very low across all three tested subjects, especially math: 3% of students are proficient in math, compared with 35% in English language arts and 8% in science.
English language arts is Sierra Vista’s strongest result relative to the state and district, while math is its weakest. In 2025–2026, Sierra Vista was 14 percentage points below the state in English language arts, 28 below in science, and 35 below in math; it was 31, 36, and 38 points below the district, respectively. Compared with nine nearby schools with reported scores, Sierra Vista ranked third-lowest in English language arts, second-lowest in math, and third-lowest in science. Only Ruben Salazar Continuation had a lower nearby math result.
Scores have declined overall since 2022–2023, though there were intervening improvements: from 2024–2025 to 2025–2026, proficiency fell by 7 points in English language arts, 4 in math, and 7 in science. Chronic absenteeism also remains a serious concern: it was 54% in 2025–2026, versus 21% in the district and 18% statewide, despite improving by 15 points from the prior year. SchoolDigger’s overall ranking fell 10 points, from the 31st percentile in 2024–2025 to the 21st percentile in 2025–2026; the school has 1 star. Its 2024–2025 student–teacher ratio was 21.9, near the nearby-school average of 20.2, and 80% of students were free/reduced lunch eligible that year. One notable subgroup result stands out: SchoolDigger ranked English Language Learner Students at the 85th percentile in 2022–2023, compared with the school’s overall 36th percentile, a stronger statewide ranking for how well the school served that group. The Male Students ranking later fell from the 35th percentile in 2023–2024 to the 20th in 2025–2026, a sharper drop than the overall ranking’s decline from the 29th to the 21st percentile.
