The National Association of Independent Schools (NAIS) is a membership organization with 501(c)(3) nonprofit status. NAIS represents approximately 1,400 independent schools and associations in the United States, and affiliates with independent schools abroad as well.

The NAIS mission is rooted in the core values of independence, interdependence, inclusivity, and innovation. We believe the freedoms derived from independence and self-determination are deserving of preservation, worthy of emulation, and a source of the success of independent schools in preparing students to contribute effectively toward a peaceful, prosperous, just, and equitable world. The National Association of Independent Schools (NAIS) exists to represent and sustain schools that are self-determining in mission and program, free from government control, and governed by independent boards. NAIS serves independent schools, adjusting focus as emerging issues dictate. NAIS is a hub of resources and expertise on matters relating to schools. We embrace innovation, powered by creativity; networking; and energy around valuing, sustaining, and growing independent schools. The practice of NAIS is high tech and high touch, high performance and high integrity.
