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.

NSF Engines Eligibility Update


The U.S. National Science Foundation recently identified an issue regarding the eligibility of certain organization types to lead a proposal responsive to the current NSF Regional Innovation Engines (NSF Engines) funding opportunity (NSF 24-565). Specifically, statutory language pursuant to the “CHIPS and Science Act of 2022” presently limits eligible NSF Engines lead organizations to institutions of higher education (IHE); non-profit, non-academic organizations; and for-profit organizations [42 U.S.C. 19108 (e)]. The NSF Engines funding opportunity additionally includes tribal nations as well as state and local governments among the list of organizations eligible to lead, which is inconsistent with the above limitation.

The NSF Engines program team has been in contact with affected proposers to identify ways for them to move forward through the NSF merit review process fairly, while also remaining in compliance with the law.

We sincerely apologize for any confusion and/or inconvenience this issue poses to the impacted proposing teams who are all working hard to grow the innovation base for their communities and regions. NSF continues to be deeply committed to meaningful engagement with people, communities, and organizations all across the United States.
