Summary:

The Simi Valley area list includes 40 schools: 19 elementary, 3 middle, 5 traditional high schools, and 13 alternative schools, including K–12 options. The latest reported test results are from 2024–25 or 2025–26, depending on the school. Results vary sharply even among schools serving similar grades, so there is no single performance level that describes schools across the area.

Vista Elementary leads elementary schools in 2025–26 ELA and math, with 80% and 75% proficient—31 and 37 points above state results. Big Springs Elementary leads elementary science at 62%, 26 points above the state. Among traditional high schools, Santa Susana High stands out with 82% ELA, 51% math, and 68% science, beating state results by 33, 13, and 32 points. The contrast is Apollo High, at 8% ELA, 0% math, and 4% science—41, 38, and 32 points below state results. At the elementary level, Berylwood Elementary has the lowest reported ELA and math results, while Knolls Elementary has the lowest science result, at 5%.

Recent trends differ by level: across the same 18 elementary schools, average ELA and science results each fell about 1 point from 2024–25 to 2025–26, while math was nearly flat; the four traditional high-school averages rose 2 points in ELA, 3 in math, and 4 in science, moving closer to state results. SchoolDigger rankings also show contrasting paths: Santa Susana High remained in the 90th–95th percentile band, while Santa Susana Elementary moved from the 33rd to 19th percentile and Arroyo Elementary from the 41st to 24th. Ratios alone do not predict results: Apollo High has a 7.3 student–teacher ratio, compared with 20.3 at Santa Susana High. For context, free/reduced lunch eligible shares in 2024–25 were 68% at Santa Susana Elementary and 67% at Arroyo; their 2025–26 ELA results were 28% and 30%.
