NIH is transitioning to updated terminology regarding funding opportunities to better align with the Uniform Guidance. Effective immediately, NIH will use the term notice of funding opportunity (NOFO) to refer to formal announcements of the availability of Federal funding through a financial assistance program. Previously, such announcements were referred to as funding opportunity announcements (FOAs). See the NIH Grants & Funding Glossary for the full definition. NIH is currently updating its website with these changes.
