Elementary Schools in Sonoma Valley Unified

Summary:

This analysis examines the four K-5 elementary schools within the Sonoma Valley Unified school district, revealing significant differences in academic performance and resources among them.

Prestwood Elementary stands out as the district's top performer, leading in English, math, and science proficiency and earning the best state ranking, though it also has the highest rate of chronic student absenteeism. Flowery Elementary shows specific strengths in science and math and has the lowest chronic absenteeism rate. Sassarini Elementary and El Verano Elementary have similar, lower academic rankings, with El Verano having the highest student-teacher ratio.

As a group, these schools trail behind California state averages in all core subjects, with math being a particular challenge across the district. Interestingly, higher per-student spending does not directly correlate with better academic results. Parents should note that performance can vary significantly by grade level, with math scores typically declining in the higher elementary grades at all schools.
