All CTOS courses are subject to a DHS certification process that utilizes third-party subject matter experts to validate the content of the course materials and ensure that the lessons are meeting industry standards and regulations. In addition to all courses undergoing certification, all CTOS instructors must complete the DHS and NDPC Instructor Certification Programs. Instructors all possess both DHS and NDPC Instructor Certifications, which provides CTOS with a consistent approach to ensuring only highly skilled instructors with both field and classroom experience deliver DHS-sponsored training.
