National Register of Historic Places: Selected States and Tribes Identified Challenges to Participation

The National Park Service (NPS) administers the National Register in cooperation with states and Tribes. Each state has established a State Historic Preservation Officer (SHPO) whose responsibilities include identifying and nominating eligible properties to the National Register. Additionally, Tribes may elect to establish a Tribal Historic Preservation Officer (THPO). Officials from SHPO offices GAO interviewed identified a number of challenges with the National Register process, including that some key NPS guidance documents were outdated and did not have inform.
