Rocketship Delta Prep scores 34 of 100 on SchoolScope's Scope Score — the 33rd percentile of 5,744 California elementary schools (CDE CAASPP 2025).

Most rating sites would stop at “30% proficient” and call it done. Rocketship Delta Prep deserves a closer read. The school sits in Antioch, where more than half of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
As a charter, Rocketship Delta Prep enrolls by application, not address — the score reads the same, the enrollment path doesn't.
