Summary

Sassarini Elementary is a K–5 school in Sonoma, in the Sonoma Valley area, serving 281 students. In 2025–2026, student proficiency was 27% in English language arts (ELA), 21% in math and 20% in science. The school’s strongest result relative to its district was math, but its overall results show a broad challenge: proficiency was below California’s in all three tested subjects.

Compared with the four nearby K–5 schools that reported results, Sassarini was 2 points below their average in ELA, 3 below in math and 7 below in science; it ranked last of the five in math and science. Math is a relative strength against Sonoma Valley Unified: Sassarini was 2 points above the district, though 17 below the state. ELA was 23 points below the state and 7 below the district, while science was 16 below the state and 4 below the district. Fourth grade stood out positively, with results above the district in both ELA and math. Fifth grade was weaker: it had the lowest ELA and math results among the five same-grade peers, and was 11 points below the district in ELA and 6 below in math.

Results have weakened over the four years reported: ELA fell 3 points and math fell 6, while science was unchanged overall. Over that period, the state gap widened by 5 points in ELA, 10 in math and 6 in science. SchoolDigger ranked Sassarini in the 17th percentile statewide with 1 star in 2025–2026, down from the 31st percentile two years earlier; it was lowest among seven nearby schools with a ranking. The student–teacher ratio was 21.6 in 2024–2025, the lowest reported among the 11 nearby schools, and 45% of students were free/reduced lunch eligible that year. A notable subgroup result: SchoolDigger placed English Language Learner Students at the 56th percentile in 2023–2024, compared with the schoolwide 31st percentile that year. Its Hispanic Students ranking fell from the 30th percentile in 2023–2024 to the 9th in 2025–2026.
