Summary:
ZIP code 94121 has five San Francisco Unified schools serving 4,312 students: three elementary schools for grades K–5, one middle school for grades 6–8, and one high school for grades 9–12. Their unweighted averages were 68% proficient in ELA, 61% in math, and 58% in science, compared with state results of 49%, 38%, and 36%. The most important finding is that all five schools scored above the state in all three subjects; even Washington (George) High, lowest in math, was 6 points above the state.
Lafayette Elementary is the broad academic standout, leading in ELA at 75% and math at 75%; those scores were 8 and 18 points above the other four schools’ averages. Alamo Elementary leads in science at 72%, 18 points above the other schools’ average. At the lower end, Argonne Elementary had the lowest ELA result at 59%, still 10 points above the state. Washington had the lowest math and science results, at 45% and 51%—6 and 15 points above state results. Among elementary schools, grade-level results add nuance: Lafayette leads in grades 3 and 4, while Alamo leads in grade 5.
Recent results are mixed: the five-school average rose 0.3 points in ELA, compared with 0.5 for the state; it fell 3 points in math while the state gained 1, and rose 1 point in science while the state gained 3. Presidio Middle improved in all three subjects, and all five schools ranked at or above the 80th percentile in SchoolDigger’s 2025–2026 statewide rankings; Presidio ranked 90th and Washington 83rd. Attendance may also matter to families: chronic absenteeism was 16% at Presidio but 36% at Washington, compared with 18% statewide and 33% in San Francisco Unified. For context, 2024–2025 free/reduced lunch eligible shares at the elementary schools were 30% at Lafayette, 38% at Argonne, and 41% at Alamo; these figures are observations, not explanations of test results. All-grades comparisons span different grade levels, so they are broad guides rather than like-for-like comparisons.
