What this means: About 63% of students here test proficient in math and reading, well above the roughly 45% typical for Texas schools with a similar share of low-income students. BeatsExpectations ranks schools against others at the same poverty level, not by raw scores, so a school can post high scores and still fall short of its prediction, or post lower scores and still beat it. This school clears its prediction by about 17 points, placing it in Texas's top 10%.

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