Resubmission Applications

A resubmission is an unfunded application that has been modified following initial review and resubmitted for consideration.

  • A resubmission has a suffix in its application identification number, e.g., A1. (Resubmissions were previously called “amended” applications, hence “A1”.)
  • You may resubmit after a new, renewal, or revision application­­­­­, as specified by the funding opportunity announcement.
  • We allow only one resubmission for each new (A0), unfunded application.
  • You may resubmit using a different PA, PAR, or PAS program announcement that accepts resubmissions, provided eligibility and other requirements are met. However, you must submit a new application (not a resubmission) if switching between a program announcement and request for application (RFA).
  • You may submit an unfunded new application as new again, without a resubmission.
  • Before a resubmission application can be submitted, the PD/PI must have received the summary statement from the previous review.
  • You must resubmit within 37 months of the application it follows.  Thereafter, the application must be submitted as a new application.
  • After an unsuccessful resubmission (A1), you may submit the idea as a new application.
  • After an unsuccessful submission and/or resubmission of a renewal application, your only option for a subsequent application is to submit as a new application.  While you can submit a renewal resubmission application after an unsuccessful renewal application, you cannot submit a second renewal application following an unsuccessful renewal application.
  • The NIH will not accept duplicate or highly overlapping applications under review at the same time, except in certain limited circumstances.
Application Requirements for Resubmission Applications
  • You may need to make significant changes to the resubmission, compared to the new application that it follows.
  • You must include an introduction for all resubmission that:
    •  summarizes substantial additions, deletions, and changes to the application
      • individual changes do not need to be identified within other application attachments (e.g., do not highlight, color, bold or italicize changes in Research Strategy)
    • responds to the issues and criticism raised in the summary statement
    • is one page or less in length, unless specified otherwise in the FOA or is specified differently on our table of page limits.
  • You may choose to submit an introduction for individual components of a multiproject application; it is not required at the component level.
  • A resubmission of a revision uses the same one page for all introductory information.
  • Career development and fellowship applicants must arrange for resubmission of the three reference letters required for those programs.
