NIH has posted a Notice in the NIH Guide for Grants and Contracts announcing that NIH encourages grantees to develop an institutional policy requiring an Individual Development Plan (IDP) for every graduate student and postdoc supported by any NIH grant, regardless of the type of NIH grant that is used for support.
IDPs are a useful tool to help graduate students and postdocs identify their career goals and what they need to accomplish to achieve those goals. The IDP process also can facilitate communication between faculty mentors and their trainees.
