Heads Up: NSF proposals for postdoc support require a separate mentoring plan.
If you are submitting a new National Science Foundation (NSF) proposal and requesting funding for a postdoctoral researcher, NSF now requires a specific plan for mentoring the postdoc. The January 2009 requirement was to include this plan in the project description. This was revised in April 2009 to include that plan as a 1-page Supplemental Document.
The revised NSF Grant Preparation Guide says: Postdoctoral Researcher Mentoring Plan: Each proposal that requests funding to support postdoctoral researchers must include, as a supplementary document, a description of the mentoring activities that will be provided for such individuals. In no more than one page, the mentoring plan must describe the mentoring that will be provided to all postdoctoral researchers supported by the project, irrespective of whether they reside at the submitting organization, any subawardee organization, or at any organization participating in a simultaneously submitted collaborative project.
