This course provides initiative commanders an orientation to the HIDTA Program, in a self-study format that allows independent learning about the HIDTA Program. This guide contains HIDTA-wide information, and each HIDTA may provide additional local information, as needed. Therefore, the course varies among HIDTAs, and it also may vary for different types of initiatives. No prior knowledge of HIDTA is required, but participants should know about the practices of his or her work. For example, an enforcement initiative commander should know drug law enforcement activities and practices. Similarly, a commander of an intelligence initiative should have in-depth knowledge of intelligence practices and criminal intelligence regulations such as 28 CFR, Part 23.
