Summary:
ZIP code 94952 has 21 listed schools: 14 elementary, two middle, four high and one alternative, serving students from elementary grades through high school. The most important finding is how widely results vary from school to school: the gap between the highest and lowest all-grades proficiency rates is 69 to 82 percentage points, depending on the subject.
Petaluma Accelerated Charter leads all schools in 2025–26 ELA, math and science, with 89%, 85% and 78% proficient—about 40, 47 and 42 points above the state, respectively. SchoolDigger ranks it 21st of 2,703 California middle schools, at the 99th percentile. Among elementary schools, Grant Elementary leads in ELA and math at 72% and 70%, while Liberty Elementary stands out in math and science at 84% and 72%.

The two middle schools also differ grade by grade: in seventh grade, Petaluma Accelerated Charter had 96% ELA and 86% math proficiency, versus 56% and 41% at Petaluma Junior High.
