Through 2006, representatives from over two dozen federal agencies, nonprofit professional organizations, and not-for-profit organizations came together to agree on the definitions of common terminology used by interpreters, environmental educators, historians, and others in nonformal settings such as parks, aquariums, zoos, nature centers, historic sites, and museums.
The result of their work is included in this website and is available copyright-free for download or web-based use by anyone who needs it. Please also feel free to provide a direct link to this website from your organization's website.
The Definitions Project was initially funded by the US Environmental Protection Agency. It has been organized by the National Association for Interpretation (NAI) in cooperation with US Fish and Wildlife Service and Institute for Learning Innovation.
