Very small groups may be suppressed in the source, so categories do not always sum exactly to total enrollment.

below demographic expectation
What this means: About 42% of students here test proficient in math and reading, below the roughly 65% typical for North Carolina schools with a similar share of low-income students. BeatsExpectations compares each school with others at the same poverty level, not by raw scores, so a school lands here when its results trail those comparable schools, which is not the same as having low scores. A higher-scoring school can still fall in this tier if similar schools score higher still.
BeatsExpectations runs a per-state regression of proficiency on free/reduced-lunch share, then scores each school by residual. How this is calculated →
