National Association For Interpretation

What National Association For Interpretation does

National Association for Interpretation (NAI), a 501(c)(3) nonprofit formed in 1988 from the merger of the Association of Interpretive Naturalists (1954) and the Western Interpreters Association (1969), is the only national US professional association dedicated to advancing heritage interpretation — the practice of connecting visitors to natural, cultural, and historical resources at parks, museums, zoos, aquariums, botanical gardens, and similar sites. The organization is headquartered in an owned 8,400-square-foot office and training facility in Fort Collins, Colorado, and operates with a lean staff of approximately eight employees under Executive Director Paul Caputo.

NAI's product portfolio is built around individual and commercial membership (5,336 active members per the homepage) coupled with two industry-recognized certifications — the Certificate of Interpretive Guiding (CIG) and Certificate of Interpretive Hosting (CIH) — delivered in-person at partner institutions and synchronously online via Zoom, with 825 professionals currently certified and 19,599 cumulative certificate holders. Complementary offerings include an annual national conference (~800 participants), an international conference rotated through global locations every other spring, the Legacy members' magazine (with a Spanish edition, Legacy en español), the InterpPress publishing imprint, an online learning and webinar series, the Interpreter's Network community platform, a Career Center, a Mentor Match program, scholarships and grants, and an e-commerce merchandise store operated on Printful.

Revenue is generated across five streams: recurring membership dues, professional development course fees (CIG $525 member / $600 regular; CIH $350 member / $425 regular, with a one-year complimentary membership bundled into first course registration), conference and event registrations, publications and merchandise sales, and tax-deductible donations channeled through an Annual Fund. Distribution is direct-to-consumer via the nai-us.org website and partner-hosted venues, augmented by organic social channels (Facebook, Instagram, LinkedIn, Bluesky) and email outreach. NAI has no disclosed parent company, no subsidiaries, and no venture or private equity ownership; it is governed by a Board of Directors and operates as an independent 501(c)(3) under FEIN 84-1036938.

Broad incumbents

• International Council of Museums: ICOM is the global professional body for museums and museum professionals across more than 140 countries. It is comparable to NAI as a broader incumbent operating in the same international heritage-interpretation space, where NAI's international conference and 30+ country reach intersect with ICOM's global membership and professional-standards mission.

Direct peers

• The Wildlife Society: The Wildlife Society is the international professional association for wildlife biologists, managers, and educators, including interpretive naturalists and educators in natural-resource settings. It is directly comparable to NAI through overlapping member roles (naturalists, rangers, environmental educators), a similar certification/publications/conference model, and a shared employer base at parks and refuges.
• National Trust for Historic Preservation: National Trust for Historic Preservation is a leading membership-based organization serving historic preservation professionals and engaged volunteers. It is comparable to NAI in operating a membership, publications, and conference model for an overlapping audience of historical-site interpreters, preservation staff, and heritage volunteers.
• Association of Zoos and Aquariums: AZA is the accreditation body and professional association for zoos and aquariums in North America. It is directly comparable to NAI because several of NAI's primary employer categories (zoos, aquariums) and member roles (interpretive staff) fall within AZA's institutional membership, and both organizations deliver accreditation, training, and conferences to overlapping audiences.
• American Alliance of Museums: American Alliance of Museums is the largest national professional association serving the museum field, offering accreditation, certification, professional development, conferences, and publications. It is directly comparable to NAI as a parallel professional membership organization for a heritage/cultural institution workforce, with overlapping member segments (museum interpreters, educators, curators) and a similar dues-plus-certification revenue model.
• American Public Gardens Association: APGA is the professional association for public gardens and arboreta, a primary employer category of NAI members. It offers accreditation, professional development, and an annual conference that mirrors NAI's structure, making it a tightly comparable direct peer for the botanical-garden interpretive workforce.
• National Recreation and Park Association: NRPA is the national professional association for park and recreation professionals, directly serving many of NAI's primary customer segments (park rangers, naturalists, recreation staff). It operates a comparable membership, certification, conference, and professional-development model for an overlapping interpretive/outdoor-recreation workforce.
• American Association for State and Local History: AASLH is the national professional association for state and local history organizations, including historical sites where many NAI members work. Comparable as a peer membership organization offering accreditation, professional development, publications, and an annual conference targeting the same heritage-interpretation workforce segment.

Emerging players

• Association of Science-Technology Centers: ASTC is a professional association for science centers and museums, employing many interpretive and educational staff. It is comparable to NAI as an emerging-player peer serving a partially overlapping audience of interpretive educators at science-focused cultural institutions.

Regional players

• National Association for Interpretation (Canada) / Interpretation Canada: Interpretation Canada is the Canadian counterpart professional association for heritage interpreters, with a closely mirrored mission, certification programs, and conference model. It is the most directly comparable regional peer, serving a parallel interpretive workforce in Canada that overlaps with NAI's international member base.
