NSF has posted its updated Proposals & Awards Policies & Procedures Guide (PAPPG, NSF 16-1), which will become effective January 25, 2016. Proposals submitted or due before January 25, 2016, and awards issued prior to January 25, 2016 should continue to use the current guide, NSF 15-1.

Significant changes to proposals include revisions to the biographical sketch, the addition of a "Collaborators and Other Information" single copy document, and information included on the current/pending support document.
