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.

Updates to NSF Research Security Policies

On July 10, 2025, NSF issued an Important Notice providing updates to the agency's research security policies, including a research security training requirement, Malign Foreign Talent Recruitment Program annual certification requirement, prohibition on Confucius institutes and an updated FFDR reporting and submission timeline.

Important NSF EDU Core Research (ECR:Core) program update

For the Oct 2, 2025 deadline, the U.S. National Science Foundation (NSF) Directorate for STEM Education (EDU) Core Research (ECR:Core) competition (NSF 21-588) will only accept proposals for fundamental STEM education research focused on undergraduate education, graduate education, higher education and the STEM workforce. These proposals should be submitted to either the Division of Undergraduate Education (DUE) or the Division of Graduate Education (DGE) as appropriate.

Investigators who would typically submit to the ECR:Core solicitation for fundamental STEM education research projects focused on early childhood or K-12 education levels or in informal settings are encouraged to apply to the NSF STEM K-12 solicitation (NSF 25-545).

Please contact ecr@nsf.gov if you have questions about ECR:Core and STEMK12@nsf.gov if you have questions about STEM K-12.
