Summary:
The Oak Grove Union Elementary district in Sonoma County operates two public schools: Oak Grove Elementary/Willowside Middle, a K-8 school serving 708 students, and Oak Grove Elementary, a separate kindergarten-only school for 91 students.
Both schools perform well academically, with the combined K-8 school consistently scoring above state averages in English, math, and science and earning 4-star ratings. A key strength for both is their very low chronic absenteeism rates—8.8% at the kindergarten school and 11.6% at the K-8 school—which are significantly better than the high 30% district average. The kindergarten school offers a slightly lower student-teacher ratio, while both schools spend the same amount per student.
When comparing performance within the K-8 school, English scores peak in 5th grade, but both math and science proficiency show notable declines in middle school grades. Despite this common challenge, the school maintains strong statewide rankings. For parents, the district offers solid educational options with particularly strong attendance records, though the academic slide in middle school math and science is an area the district is likely monitoring for improvement.
