Summary:
Zip code 91362 has eight schools—four elementary, two middle and two high schools—serving students from kindergarten through high school; seven have 2025–2026 test results, while Meadows Arts and Technology Elementary has results only through 2024–2025. The seven current schools average 59% proficient in English language arts (ELA), 49% in math and 44% in science, compared with state results of 49%, 38% and 36%. The most important finding is how widely results vary between schools: the current school-to-school ranges are 54 points in ELA, 68 in math and 71 in science, so area averages alone can hide very different school results.
Lang Ranch leads all three current all-grades subjects, with 83% proficient in ELA, 79% in math and 80% in science—33, 41 and 44 points above state results. Los Cerritos Middle leads the middle schools at 72% in ELA, 64% in math and 58% in science; Westlake High leads the high schools, with grade 11 results of 64%, 50% and 53%. At the lower end, Conejo Academy of Leadership and Language Immersion (CALI) has the lowest current all-grades ELA result, 29%, while Conejo Valley High (Continuation) has the lowest math and science results, 11% and 9%. The gap between the two high schools is also large: Westlake is ahead by 35 points in grade 11 ELA, 38 in math and 44 in science.
Across the same seven schools, average ELA and math results rose by about 1 point from 2024–2025 to 2025–2026, while science was essentially unchanged; because the state’s science result rose, the schools’ average lead in science narrowed by 3 points. SchoolDigger ranks Lang Ranch at the 97th percentile and Los Cerritos at the 91st, while CALI is at the 16th and Conejo Valley High at the 23rd. As context, 2024–2025 free/reduced lunch eligible shares were similar at Lang Ranch and Westlake Hills Elementary—19% and 20%—yet Lang Ranch led by 13 points in ELA, 11 in math and 34 in science. These measures describe differences between schools but do not explain them.
