Resubmission Policy Redux

Funding News Edition: August 15, 2018
See more articles in this edition

In 2014, NIH changed its resubmission policy. The new policy, which remains in place today, allows investigators to follow their unfunded resubmission (A1) with a new application (A0) and does not require the second A0 to be significantly different from the A1. On the other hand, the second A0 is what we call a “virtual A2,” which is submitted as an A0 while it is in fact an A1 updated to address reviewer concerns.

Through a July 23, 2018 Guide notice, NIH rescinds any old notices that may contain incorrect information about its resubmission policy. The Guide notice reiterates that the NIH resubmission policy has remained unchanged since 2014 and highlights the following important points:

NIH accepts only a single resubmission (A1) of an original application (A0)

  • If your original A0 application was submitted to a program announcement (PA), program announcement with set-aside funds (PAS), or program announcement with special receipt, referral, and/or review considerations (PAR), your A1 application may be submitted to any other PA, PAS, or PAR that accepts resubmissions, given that it meets the eligibility criteria and other requirements.
  • If you decide to switch from a PA, PAS, or PAR to a request for applications (RFA), or from an RFA to a PA, PAS, or PAR, your subsequent submission must be formatted as a new A0 application.

You may submit an A0 application following an unsuccessful A0 or resubmission A1 application, with the following exceptions

  • We allow only two renewal submissions in a series—the A0 renewal and the A1 resubmission of a renewal. If your A1 resubmission is not funded, we do not accept further renewal applications in that series. If your A0 renewal application is not funded, you cannot submit another A0 renewal application in that series. You can submit only an A1 resubmission application or a new (not a renewal) application.
  • Special considerations apply to Small Business Innovation Research/Small Business Technology Transfer (SBIR/STTR) applications. See SBIR/STTR Frequently Asked Questions.

NIH does not allow a change of activity code between the A0 and A1 except in one case

  • Some funding opportunity announcements (FOAs) will change activity code at the time they are reissued. When this happens, the activity code changes are allowed and the application is an A0. For example, an A0 renewal application may change activity code when the application was funded through a FOA that changed activity code at the time of reissuance. In this case the renewal application submitted to the reissued FOA is considered to be a new application (A0).

See our August 3, 2016 article “New Submissions of Unfunded Resubmissions Find Success at Normal Rate” for advice on your resubmissions and/or second A0 applications. You may find particularly helpful the information listed under Revise and Resubmit an Application.

For additional advice on new versus resubmission applications, refer to NIH’s Resubmissions of NIH Applications Frequently Asked Questions.

Read the entire Guide notice linked above for more information.

We encourage you to update each subsequent application submission to reflect the status of the field over the interim period. Lastly, we also encourage you to incorporate new preliminary data, literature citations, and letters of reference among other items as time passes.
