Summary:

The Oak Grove Union Elementary district in Sonoma County operates two public schools: Oak Grove Elementary/Willowside Middle for grades 1-8 and a separate Oak Grove Elementary campus serving Kindergarten only, together educating about 800 students.

For parents, the standout feature across both schools is exceptionally strong student attendance, with chronic absenteeism rates far better than the California average. The Kindergarten school leads with an 8.8% rate, while the main 1-8 grade school also excels at 11.6%. Academically, Oak Grove Elementary/Willowside Middle consistently performs above state averages, showing particular strength in English Language Arts and Science, where student proficiency significantly outpaces the state.

A key area for the district to address is a noticeable decline in mathematics scores as students progress; while third graders perform well, proficiency drops by the time they reach eighth grade. Overall, the schools in Oak Grove Union Elementary are characterized by stable, above-average academic rankings, high attendance, and effective science instruction, with a clear opportunity to strengthen math support in the upper grades.
