Summary:

ZIP code 91945 has seven schools: six elementary schools, including a kindergarten-only early childhood center, and one middle school; six schools have reported test results. In 2025–2026, the six-school averages were 40% in ELA, 29% in math and 30% in science, all below state averages of 49%, 38% and 36%. The clearest finding is that results vary widely by school, especially in science, where the top-to-bottom spread was 26 percentage points.

Lemon Grove Academy for the Sciences and Humanities led all-grades ELA at 50%, about 1 point above the state and 10 points above the area average. Monterey Heights Elementary led math at 36% and science at 41%; its science score was 5 points above the state. At the low end, San Miguel Elementary had the lowest ELA result, 28%—21 points below the state. Lemon Grove Academy Elementary recorded the lowest math and science results, 23% and 15%; its science score was 21 points below the state.

Science improved most over time: the area average rose from 23% in 2024–2025 to 30% in 2025–2026, narrowing its gap with the state from 9 to 6 points. ELA was essentially flat at about 40%, while math fell from 31% to 29%; the math gap with the state widened from 6 to 9 points. Grade-level results offer another point of comparison: San Altos Elementary reached 62% in 6th-grade ELA, 14 points above the state. SchoolDigger ranks Monterey Heights and Mt. Vernon Elementary at the 50th percentile, compared with the 23rd percentile for San Miguel. As context, elementary-school free/reduced lunch eligible figures for 2024–2025 ranged from 67% at Monterey Heights to 83% at Lemon Grove Academy Elementary; these figures describe student context, not a cause of results.
