National Association of Federally Impacted Schools (NAFIS) represents approximately 1,100 federally impacted public school districts that together educate more than eight million students across the nation. Federally impacted school districts are those located on or near nontaxable Federal property—including military installations; Indian Trust, Treaty and Alaska Native Claims Settlement Act lands; Federal low-income housing facilities; and national parks, national laboratories and other Federal buildings and property. These school districts, which are demographically and geographically diverse, receive Impact Aid.
