Summary:
91776 has seven schools—three elementary, one middle and three high—across Alhambra Unified, San Gabriel Unified and Garvey Elementary. The schools’ 2025–26 averages are close to state proficiency levels: 50% in ELA versus 49% statewide, 38% in math versus 38%, and 36% in science versus 36%. Those averages conceal much wider differences between schools: the highest-to-lowest gaps are 32 points in ELA, 44 in math and 34 in science. The most important takeaway is that school-level results vary sharply across the area, so the overall average does not represent every school’s experience.
Jefferson Middle leads all three all-grades subjects, with 65% proficiency in ELA, 51% in math and 52% in science—16, 12 and 16 points above state results, respectively. The high schools Gabrielino High and San Gabriel High also post strong results: Gabrielino has 63% in ELA, 50% in math and 52% in science; San Gabriel has 63%, 46% and 47%. At the lower end, Dewey Avenue Elementary has the lowest ELA result at 33%, while Del Mar High has the lowest math and science results, at 7% and 18%. Del Mar also reports 69% chronic absenteeism and a 78% graduation rate, compared with 18% and 88% statewide.
Recent changes are mixed: from 2024–25 to 2025–26, the seven-school average rose 1 point in math and was nearly unchanged in ELA and science, while the state’s science result rose 3 points. Individual schools differed: San Gabriel High gained 3 points in ELA, 4 in math and 12 in science; Jefferson gained 3, 4 and 4 points, while McKinley Elementary’s science result fell 15 points. SchoolDigger’s 2025–26 state percentiles are 83rd for Jefferson and Gabrielino and 79th for San Gabriel; Roosevelt and Dewey are at the 40th and 35th percentiles. The reported low-income measure is free/reduced lunch eligible for 2024–25: rates range from 66% at San Gabriel High to 89% at Del Mar, but these figures alone do not explain school results.
