Summary:
Schools in zip code 91342 include 15 schools—10 elementary, one middle and four high schools—with 2025–2026 all-grades test results available for 13 of them. Results vary widely: school scores span 55 percentage points in English language arts (ELA), 42 points in mathematics and 32 points in science. That range means a zip-code average would hide important differences between schools; the most important finding is how uneven results are across the area.
Sylmar Biotech Health and Engineering Magnet leads ELA at 59%, 8 points above Brainard Elementary, and is 9 points above the 49% state figure. Brainard leads mathematics at 52%, 8 points ahead of Harding Street Elementary, and 14 points above the state’s 38%. Dyer Street Elementary leads science at 39%, 4 points ahead of Sylmar Biotech and 3 points above the 36% state figure. At the other end, Evergreen Continuation scores 3% in ELA, 10% in mathematics and 6% in science—46, 28 and 30 points below state results, respectively.
Across the same 13 schools, average ELA scores fell 2 points from 2024–2025 to 2025–2026, mathematics rose 1 point and science was essentially unchanged. The average state gap widened in ELA, from 5 to 7 points below state, and in science, from 7 to 10 points below; mathematics remained about 4 points below. Individual results differ: El Dorado Avenue Elementary gained 12 points in ELA, while Brainard fell 15; Sylmar Elementary gained 11 points in science. As context, reported free/reduced lunch eligible shares in 2024–2025 ranged from 74% at Brainard to 96% at Sylmar Elementary; these figures alone do not explain score differences.
