The purpose of the IDP is to ensure the development of newly appointed full-time staff instructors who are responsible for the basic Postal Inspector and Postal Police Officer training programs. The course is delivered in a blended learning format to include teaching competencies and technical aspects of course development. The IDP is comprised of three courses: Facilitative Instructor Training (FIT) Online, FIT Classroom, and Advanced FIT Online. The FIT Online and Advanced FIT Online, are both self-paced, however, the FIT Classroom is a one and a half-day (12 hour) instructor-led classroom-based course. The number of IDP participants will vary year to year and the classroom is limited to 6-8 participants per iteration.
