Who it serves
The measures behind the prediction
Bars: this district. Black tick: Colorado average across ranked districts, weighted by students.
Parents’ education: parents of public-school children (Census ACS 2019–2023, NCES tabulation). For context, not in the prediction: all adults with a bachelor’s degree+ 39%; median household income $110,129.
Its schools
Neighborhood schools
Compared with Colorado schools serving similar students (income and education of the area, free/reduced lunch, English learners, special education). Points are CMAS scale-score points vs. expected, 2024–2026.
The expected result comes from a statistical model fit across all ranked Colorado districts: parents’ education, free/reduced lunch, English learners and special education explain about 90% of the differences in district results. Over/under is what remains — the part the demographics don’t account for, which includes the schools themselves but also anything else those measures miss. Each district’s expected value is predicted from the other districts. Full method and caveats.
