Not compared with neighborhood schools
Charter, choice, magnet, online and alternative schools don’t serve a neighborhood, so they aren’t compared with schools serving similar areas. Charter and online schools are also left out of the district results above.

How to read this

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.
