Summary:
ZIP code 91326 has four elementary schools in Los Angeles Unified: three serve kindergarten through grade 5, while Porter Ranch Community serves kindergarten through grade 8. In 2025–2026, the schools’ average all-grade proficiency was 73% in English language arts (ELA), 71% in mathematics, and 62% in science—24, 33, and 26 percentage points above state results, respectively. The central takeaway is that all four schools beat the state in all three subjects, though their results vary considerably.
Beckford Charter for Enriched Studies is the clear performance leader, with 85% proficiency in ELA, 84% in mathematics, and 74% in science. It leads the next-highest school by 9 points in ELA, 12 in mathematics, and 7 in science. Darby Avenue Elementary is lowest in all three subjects, at 60%, 58%, and 43%, respectively; the gap between the top and bottom school ranges from 26 to 31 points. The same pattern appears in grades 3–5, where Beckford leads and Darby trails in ELA and mathematics.
Recent changes are mixed: from 2024–2025 to 2025–2026, the four-school average fell 3 points in ELA, was essentially flat in mathematics, and rose 1 point in science, while the average lead over the state narrowed in every subject. Beckford improved in all three subjects, while Darby fell 6 points in ELA, 4 in mathematics, and 13 in science. SchoolDigger ranks Beckford at the 99th percentile statewide and Darby at the 77th; Porter Ranch is at the 92nd and Castlebay Lane Charter at the 91st. For 2024–2025, free/reduced lunch eligible shares were 30% at Beckford, 27% at Castlebay, 22% at Porter Ranch, and 55% at Darby; these figures are context, not an explanation for results. Darby also has the lowest student-teacher ratio, 22.8, compared with 23.7–24.5 at the others. Porter Ranch’s K–8 span means its all-grade results are less directly comparable with those of the K–5 schools.
