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.

Practical use of this page is in combination with the comparison and ranking pages elsewhere on the site, which surface the same data for this entity’s peers within U.S. public schools and districts. A single-entity reading without peer context can be misleading when an entity is an outlier on one axis but typical on another.
