From the NASAA site:

[NASAA] is the professional association of the nation’s 56 state and jurisdictional arts agencies. NASAA is a national, not-for-profit, nonpartisan organization that champions public support for the arts in America.

Together, NASAA and the state arts agencies advance the arts as an essential ingredient in the well-being and prosperity of our nation’s individuals, communities and families. State Arts Agencies (SAAs) support lifelong learning in the arts, and with NASAA’s leadership have begun to prioritize creative aging programming as core to their work.
