Schools in ZIP code 90249 include three elementary schools serving kindergarten through grade 5 or 6 and one high school serving grades 9–12, with 1,586 students in all. The elementary schools’ 2025–2026 averages were above the state in ELA (57% versus 49%), math (53% versus 38%) and science (46% versus 36%), but those averages hide large differences between schools.

Chapman Elementary led in math at 67% and was also above the state in ELA and science. At the other end, Purche Avenue Elementary scored 32% in ELA, 28% in math and 13% in science—below the state in each subject. Environmental Charter High - Gardena, the only high school in the list, had a mixed profile in 2024–2025: ELA was 71% and science 36%, both above the state, while math was 26%, below it.
Elementary results mostly improved from 2024–2025 to 2025–2026, but not at every school: Chapman rose 5 points in ELA, 11 in math and 7 in science; One Hundred Fifty-Sixth Street rose 3, 1 and 10 points, respectively. Purche’s ELA rose 4 points, while math fell 2 and science fell 8.

In 2024–2025, free/reduced lunch eligible rates were 63% at Chapman, 68% at One Hundred Fifty-Sixth Street and 90% at Purche; these are context, not an explanation of results.
