Summary:
Lemon Grove has eight schools—seven elementary schools and one middle school—serving kindergarten through middle school; Lemon Grove Early Childhood Education Center serves kindergarten only. Across the seven schools with 2025–2026 results, the average proficiency was 40% in ELA, 29% in math and 31% in science, compared with state results of 49%, 38% and 36%, respectively. The most important finding is that the group average is below the state in all three subjects, with the widest shortfall in ELA.
Several schools stand out, but strengths differ by subject. Lemon Grove Academy for the Sciences and Humanities led ELA at 50%—about 10 points above the next-highest school and 1 point above the state—while its math and science results were below state levels. Monterey Heights Elementary led math at 36% and science at 41%; its science result was 5 points above the state, while its math result was 2 points below. At the lower end, San Miguel Elementary had the lowest ELA result, 28%, and Lemon Grove Academy Elementary had the lowest science result, 15%. The science gap between the highest- and lowest-scoring schools was 26 percentage points.
Science results improved across the area: the seven-school average rose 7 points from 2024–2025 to 2025–2026, and six schools improved. The exception was Lemon Grove Academy Elementary, down 14 points; meanwhile, the group’s math average fell 1 point as the state average rose 1 point. SchoolDigger’s 2025–2026 rankings also vary: Lemon Grove Academy for the Sciences and Humanities ranked in the 52nd percentile, while San Miguel was in the 23rd; Lemon Grove Academy Elementary fell from the 47th percentile the prior year to the 27th. As context, the schools reported 67%–83% free/reduced lunch eligible in 2024–2025; Monterey Heights, at 67%, led math and science, but these figures do not explain results. All-grade comparisons cover seven schools; the kindergarten-only center has no test-score figures, and schools serve different grade spans.
