What this means: About 52% of students here test proficient in math and reading, compared with the roughly 45% typical for Missouri schools with a similar share of low-income students. BeatsExpectations measures results against demographically similar schools rather than by raw scores, and this school falls within the typical range, neither among Missouri's top nor bottom 10%.
