This is likely the most confused title and is often used in place of “Course Coordinator” (CC).
All CCs are Instructors, but not all Instructors are CCs.
If an Instructor is not a CC, they will not have a record in the PEPP database, nor will they ever coordinate a course of their own. Therefore, they are always assisting a CC.
A CC should never list themselves on a roster as also being an “Instructor.” As a CC, it is part of their duty to be present and active in the instruction of each course they coordinate (as stated in the Instructor's Online Toolkit and the PEPP website). There is no need for them to list themselves twice on a roster.
