Summary:
Six elementary schools are listed in ZIP code 91945: five serve kindergarten through grade 6, while Lemon Grove Early Childhood Education Center serves kindergarten only. The five K–6 schools’ 2025–26 averages were 37% in ELA, 30% in math and 30% in science, below California’s 49%, 38% and 36%, respectively. The clearest area-wide finding is that science results vary especially widely: the gap between the highest and lowest schools was 26 percentage points.
Mt. Vernon Elementary led ELA at 46%, while Monterey Heights Elementary led math at 36% and science at 41%. Monterey Heights’ science rate was 5 points above the state rate; Mt. Vernon was just above the state in science, at 36.4% versus 36.0%. At the other end, San Miguel Elementary had the lowest ELA result, 28%, and Lemon Grove Academy Elementary had the lowest math and science rates, 23% and 15%. Grade-level results add important exceptions: San Altos Elementary reached 62% in grade 6 ELA, 14 points above the state, and Academy was also slightly above the state in that grade.
Recent changes differ by subject: from 2024–25 to 2025–26, the five-school averages fell 3 points in ELA and 3 in math, while science rose 6 points; state results increased in all three subjects. SchoolDigger’s 2025–26 rankings place Mt. Vernon and Monterey Heights at the 50th percentile, San Altos at the 44th, Academy at the 27th and San Miguel at the 23rd. Student–teacher ratios range from 21.1 at San Altos to 25.7 at Monterey Heights and Academy, which have sharply different science results. In 2024–25, reported free/reduced lunch eligible shares ranged from 67% at Monterey Heights to 83% at Academy; these figures are context, not an explanation for achievement. The K-only center has no supplied test results, so it cannot be compared academically with the K–6 schools.
