National Science Foundation: Proposal Requirement Changes

The National Science Foundation (NSF) will implement the following proposal submission changes in 2023:

FastLane To Be Decommissioned

September 29, 2023 is the last day to submit proposal file updates and budget revisions in FastLane. FastLane documents will no longer be accessible after this date, so download any in-progress LOIs, proposal documents, and supplemental funding requests by this date. The Office of Sponsored Programs will not do this for you.

Reviews and summaries for proposals submitted in FastLane will remain available in

See for detailed information about FastLane system decommissioning.

Biosketches and Current and Pending Support Documents

Since the 2023 version of the Proposal and Award Policies and Procedures Guide (PAPPG 23-1) went into effect on January 30, 2023, the format of the Biosketch and Current and Pending Support documents have changed with the addition of the certification of information provided as required by the National Defense Authorization Act.

Starting with proposals submitted on or after October 23, 2023, SciENcv will be the only option for creating NSF-compliant Biosketches and Current and Pending Support documents. Documents created in the fillable PDF templates will no longer be accepted by NSF.

Faculty and staff planning to submit NSF proposals should create/update their accounts in SciENcv as soon as possible. Visit for instructions or contact Yuening Zhang, STEM Librarian ( for assistance.
