ZIP code 95688 has two high schools serving grades 9–12 and 7–12: Vacaville High enrolls 2,044 students, while Shereene Wilkerson Academy of Excellence enrolls 6. The schools differ greatly in size, and the available results do not support a complete achievement comparison. The clearest academic finding is that Vacaville High’s 2025–26 ELA proficiency was 59%, 10 percentage points above the state, while its math and science results were below state levels.
Vacaville High stands out for its reported outcomes: its 94% graduation rate was 6 points above the state, its 5% dropout rate was 3 points lower, and its 11% chronic absenteeism was 8 points lower. The Academy stands out for a much higher chronic absenteeism rate: 67%, compared with 11% at Vacaville High, a gap of 56 points. The Academy’s school-level proficiency values are state-suppressed, so the available data cannot establish which school is academically stronger. Vacaville’s all-grades proficiency was 32% in math and 32% in science, compared with 38% and 36% statewide; in the Vacaville Unified district, the corresponding rates were 29% and 28%.
