Most rating sites would stop at “62% proficient” and call it done. Buckingham Collegiate Charter Academy deserves a closer read. The school sits in Vacaville, where one in three students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
The headline number: 79.5% of low-income students met the ELA standard — versus 38.2% for the same group statewide.
As a charter, Buckingham Collegiate Charter Academy enrolls by application, not address — the score reads the same, the enrollment path doesn't.
