Selection and source notes

This list combines public charter-school profiles and private-school profiles for broad discovery; those are distinct school types, not equivalent governance models.

COSMIQ profiles record 2022 as the source year for public charter-school and private-school enrollment records. Private-school profiles use NCES Private School Universe Survey data; source coverage and school types differ.

Source references: COSMIQ education profiles; NCES Common Core of Data (charter profiles) and Private School Universe Survey (private-school profiles).

The article includes 50 profiles from the largest available enrollment estimates in this category. This is a size-based selection, not a “best schools” or academic-quality ranking.

Editorial note: COSMIQ has not independently evaluated or endorsed the listed institutions. Profile availability and source years vary; readers should consult each institution for current details.
