What this means: About 29% of students here test proficient in math and reading, well above the roughly 18% typical for Washington 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 11 points, placing it in Washington's top 10%.
