Important information about NSF’s implementation of the revised 2 CFR

NSF Financial Assistance awards (grants and cooperative agreements) made on or after October 1, 2024, will be subject to the applicable set of award conditions, dated October 1, 2024, available on the NSF website. These terms and conditions are consistent with the revised guidance specified in the OMB Guidance for Federal Financial Assistance published in the Federal Register on April 22, 2024.

Important information for proposers

All proposals must be submitted in accordance with the requirements specified in this funding opportunity and in the NSF Proposal & Award Policies & Procedures Guide (PAPPG) that is in effect for the relevant due date to which the proposal is being submitted. It is the responsibility of the proposer to ensure that the proposal meets these requirements. Submitting a proposal prior to a specified deadline does not negate this requirement.

IOS Core Proposal Submission through Research.gov


The NSF Directorate for Biological Sciences (BIO) has implemented a requirement for submission of full proposals via Research.gov (or Grants.gov) for certain program solicitations, including the Division of Integrative Organismal Systems Core Programs solicitation (NSF 21-506). If you have already started a proposal in FastLane, don’t worry, you can still submit it via FastLane. But if you are starting a new proposal, please do so via Research.gov. For more information see the Dear Colleague Letter, NSF 20-129, about this change.

Additional information, including Frequently Asked Questions (FAQs) and video tutorials, is available on the Research.gov "About Proposal Preparation and Submission" webpage. The NSF Help Desk also is available for those who encounter issues with proposal preparation or submission.

Please direct your comments and questions about this change to BIOnodeadline@nsf.gov.
