Regular communication between postdocs and supervisors is vital. Postdocs and their supervisors should plan for an introductory meeting to set overall goals and construct a mentoring plan, which must be provided with the initial appointment. The annual renewal of an appointment must include a progress report on the career development plan including future goals that is co-signed by both the postdoc and advisor and reflects an in person meeting.
MIT also recommends that postdocs complete an Individual Development Plan and a Career Planning Strategy.
Further information is in the Postdoctoral Mentoring and Advising Toolkit, along with a basic outline for a mentoring plan, suggested template for an annual review, and other related resources.
