Summary

Sunnybrae Elementary is a K–5 school with 346 students in San Mateo, part of the San Mateo-Foster City district. Its latest test results are low across all three subjects: in 2025–2026, 19% of students were proficient in English language arts (ELA), 22% in math and 10% in science. The most important finding is that Sunnybrae was second-lowest among five nearby same-district K–5 schools in all three subjects; only LEAD Elementary scored lower.

Math is Sunnybrae’s strongest subject relative to district and state results, while science is its weakest against both. Sunnybrae’s results were 28 to 35 percentage points below district levels and 16 to 30 points below state levels. It also fell below the five nearby K–5 schools’ average in every subject: those averages were 49% in ELA, 52% in math and 43% in science, compared with Sunnybrae’s 19%, 22% and 10%. In particular, science was 33 points below that peer average.

Results have not kept pace with state gains: from 2022–2023 to 2025–2026, Sunnybrae’s ELA proficiency fell by 1 point, math was essentially unchanged, and science rose by 3 points, while state proficiency increased in all three subjects. SchoolDigger ranked Sunnybrae at the 9th percentile with 0 stars in 2025–2026; nearby same-district schools ranged from the 7th to 97th percentile. Its 2024–2025 free/reduced lunch eligible rate was 75%, the highest among nearby same-district schools with that measure and year. This is context, not an explanation for test results. The student-teacher ratio was 19.2 in 2024–2025, lower than all but one nearby school. A notable subgroup trend is that SchoolDigger’s statewide ranking for how well the school serves English Language Learner Students fell from the 40th percentile in 2021–2022 to the 14th in 2023–2024. Chronic absenteeism also improved, from 38% in 2022–2023 to 22% in 2025–2026, but remained above the district’s 15% and the state’s 18%.
