“Does NIH have an up-to-date guide for the FORMS-G application form set?”

Yes, find resources updated for FORMS-G at How To Apply—Application Guide and Annotated Form Sets.

As a reminder, NIH will transition from the FORMS-F application form set to a new FORMS-G application form set this winter. As explained in our September 1, 2021 article “NIH Announces FORMS-G Transition, Implementation Plans,” there will be a period of time in which you may need to choose between the FORMS-F and FORMS-G application form sets within a given funding opportunity announcement; you’ll need to choose correctly based on whether the receipt date you’re targeting is on or after January 25, 2022.
