The this entity record above pulls directly from NCES Common Core of Data and EDFacts. What follows is the per-entity context — how this entity sits in the broader U.S. K-12 school outcomes and enrollment distribution and which underlying factors drive the headline numbers.
The methodology behind every numeric value on this page is publicly documented on the NCES Common Core of Data and EDFacts portal and described in detail on this site’s methodology page.
