Best Public Schools in Zip Code 91304

Zip code 91304 has six schools: five elementary schools serving K–5 and one middle school serving grades 6–8; five have 2025–26 results, while Ingenium Charter’s latest results are from 2024–25. Among the four elementary schools with current results, average proficiency was 58% in ELA, 53% in math and 47% in science, compared with state results of 49%, 38% and 36%. The clearest overall finding is that elementary averages were above the state in all three subjects, while Canoga Park Middle was below it in all three.

Justice Street Academy Charter stands out in ELA and math, with 73% and 69% proficient—the highest current results, leading the next-highest school by 9 percentage points in ELA and 6 points in math. Pomelo Community Charter leads science at 64%, 8 points above Justice Street. At the other end, Canoga Park Middle has the lowest current All Grades results: 22% in ELA, 15% in math and 17% in science—27, 24 and 19 points below state results. Among elementary schools, Nevada Avenue Elementary is lowest in all three subjects; Capistrano Avenue Elementary is above the state in all three. Because Canoga serves middle-school grades and the others serve elementary grades, their All Grades results are not a like-for-like comparison.

Recent changes are mixed: across the five schools with back-to-back results, the average ELA score fell by 1 point, math rose by 1 point and science was nearly unchanged, while the state science result rose by 3 points. School-level changes show why: Capistrano science fell by 26 points, while Pomelo gained 14 and Justice Street gained 10. SchoolDigger ranks Justice Street at the 88th statewide percentile and Pomelo at the 84th; Pomelo and Nevada each rose 5 percentile points since 2023–24. Other measures do not follow a simple pattern: Justice Street has a 23.8 student–teacher ratio, higher than Nevada’s 18.4, yet leads in two subjects. All schools report free/reduced lunch eligible figures for 2024–25: 32% at Pomelo, 42% at Justice Street, 81% at Capistrano and 87% at Nevada; these are context, not explanations of results.
