The National Association of Independent Schools (NAIS) is a membership organization which represents approximately 1,400 independent schools and associations in the United States, and affiliates with independent schools abroad as well.

NAIS’s mission is to be the national voice of independent schools and the center for collective action on their behalf.

NAIS is a hub of resources and expertise on matters relating to schools.

The NAIS vision foresees a future where independent school graduates will make good choices for themselves, their communities, and the world, capitalizing upon those values and skills that won’t change and acquiring those new skills and values a 21st Century marketplace and global commons will demand.
