The National Institutes of Health (NIH) has provided new information to help applicants avoid common errors in the preparation of SF424 research and related activities forms. As the agency states, the new resources supplement the information already available to applicants. “When preparing an application, applicants MUST follow the instructions” in the relevant funding opportunity announcement and NIH application guide. The documents provide field-by-field tips on entering information, especially in fields that are required by NIH but are not required on federal-wide forms.
