As trainees, postdoctoral appointees must be formally mentored or co-mentored by a member of the ladder faculty (Assistant, Associate or Full Professor), or those with Yale appointments who have been approved for a promotion to a ladder rank on a specified date. As part of the annual reappointment process the mentor is expected to write an evaluation or progress report of the postdoctoral appointee’s activities in a manner that is clear and timely (IDP Evaluation Form). These reports should be provided to the appointee and forwarded to the Office for Postdoctoral Affairs. Mentors have the responsibility to provide an appropriate educational experience that helps to advance the career of the postdoctoral appointee.
