The Mission Statement of the Interpretive Development Program

Interpretive Development Program (IDP) standards, philosophies, and best practices are based on the knowledge that people care for what they first care about. The IDP enables all NPS employees to connect people to parks so that parks are preserved and future generations may make their own meaningful resource connections. The IDP maintains professional standards by providing a benchmark curriculum and developmental opportunities, integrating best practices with agency management, and operating a peer review certification program.
