The GEOINT Professional Certification (GPC) program is part of a broader Under Secretary of Defense for Intelligence and Security (USD(I&S)) initiative to further professionalize the Department of Defense Intelligence Enterprise (DIE) workforce. The program applies to all cleared Department of Defense civilian, military, and contractor practitioners in GEOINT-related work roles throughout the National System for Geospatial Intelligence (NSG). GPC may also extend to non-DoD members of the NSG with GEOINT equities.
