BeatsExpectations measures results against demographically similar schools rather than by raw scores, and this school falls within the typical range, neither among California's top nor bottom 10%.

BeatsExpectations runs a per-state regression of proficiency on free/reduced-lunch share, then scores each school by residual. How this is calculated →
