Summary:
ZIP code 94963 has one school, Lagunitas Elementary, a K–8 school with 68 students. In 2025–2026, its all-grade proficiency rates were 66% in English language arts (ELA), 47% in math and 59% in science, compared with California rates of 49%, 38% and 36%, respectively. The school was above the state in all three subjects, with its largest advantage in science at 23 percentage points.
Because Lagunitas Elementary is the only school in the ZIP code list, it is both the highest- and lowest-scoring school there by default; there is no school-to-school comparison, and its 68-student enrollment means grade-level percentages may reflect results from relatively few students. Within the school, grade 5 ELA stood out: 95% were proficient, compared with 49% statewide, a 46-point advantage. Grade 6 ELA was 43%, 5 points below the state. In math, grade 7 reached 69%, 31 points above the state’s 38%, while grade 4 was 33%, 9 points below the state’s 42%. These grade differences show that strong all-grade results do not mean results are equally strong in every grade.
Results shifted in different directions from 2024–2025 to 2025–2026: ELA fell 8 points and math fell 14 points, while science rose 6 points. The school’s advantage over California narrowed by 8 points in ELA and 15 in math, but grew by 2 points in science. Separately, SchoolDigger’s ranking rose from the 40th percentile in 2015–2016 to the 58th in 2017–2018 and the 72nd in 2025–2026; its rating went from 2 to 3 to 4 stars. Chronic absenteeism in 2025–2026 was 12% at the school versus 18% statewide. The school reported 13% free/reduced lunch eligible in 2024–2025, while all students in California receive free school meals; these are context measures, not explanations for test results.
