BeatsExpectations
Demographically-adjusted score · methodologyWhat this means: About 25% of students here test proficient in math and reading, below the roughly 40% typical for Illinois 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.
