Applying for a Revision to a Grant Award SOP

Lock icon: This link will not work for public visitors.Some links will work for NIAID staff only.

This standard operating procedure (SOP) includes the following sections: Purpose, Procedure, Contacts, and Links.


To provide instruction for awarding competitive revision applications, which are requests from grantees for a significant expansion of a project's scope and for additional funds.


Grantees who want to expand their project's scope may request a revision (also known as a competitive revision or a competing supplement); however, they must submit an application, which must undergo peer review and be selected for funding. For more information on expanding scope, see What Constitutes a Change in Scope? in the Strategy for NIH Funding.

Investigators may apply for revisions only in response to a revision funding opportunity announcement (FOA) and only if the parent application has been funded. Revisions may not extend beyond that grant's project period.

*Note: In general, revision applications are not allowed for awards issued under a parent FOA with a single due date unless the revision FOA specifically states they are. Revision applications are generally allowed for awards issued under an investigator-initiated program announcement with multiple due dates. The revision FOA will define eligibility.

Also, revisions do no restore funds that were part of standard grant reductions.

See the Administrative Supplements to Grants and Cooperative Agreements SOP for adding funds to a grant or cooperative agreement for purposes that do not significantly expand a project's scope.


  • Check the revision FOA to see if revisions are allowed for your award. If they are, discuss the possibility of applying for one with your program officer, focusing on the scientific need.
  • If you need $500,000 or more in direct costs in any year, get approval from your program officer at least six weeks before applying.
    • When you apply, submit documentation stating that you've discussed direct costs with your program officer and that NIAID has agreed to accept your application.
    • See the Big Grants SOP for more information.
  • Discuss the revision application with your grants management specialist, focusing on the dollars and policy issues.
  • Send a full application requesting funds for new Specific Aims. Keep the title, but do not resubmit the original application.
    • For most grant types, including R01s, you may apply electronically even if you originally applied in paper. Read the competitive revision FOA for detailed application instructions.
    • Prepare a one-page introduction:
      • Describe the objective of the revision and how it influences the Specific Aims and Approach section of the Research Strategy.
  • In the body of your application, include enough information from your original application to enable reviewers to evaluate the revision in relation to the original.
    • In the Preliminary Studies/Progress Report section:
      • Include a progress report with the project period beginning and end dates of the parent award, a summary of the importance of your findings in relation to your Specific Aims, and an account of progress toward achieving your aims.
      • You can either include this as a subsection of the Approach section or integrate it into any of the three main sections of the Research Plan.
      • If you do the latter, be sure to mark the information clearly, for example, with a bold subhead.
    • If your application includes a line of investigation not recommended by the scientific review group, respond to the criticisms in the summary statement by adding data obtained since your original application or revising substantially.
    • If you are requesting to revise the aims, mark revisions clearly and summarize them in your introduction.
  • For information on research involving human subjects, go to Human Subjects Resources on Research Funding.

Program and Grants Staff

  • Advise investigators about the need and feasibility of obtaining a revision.

Scientific Review Staff

  • If the parent grant was reviewed at NIAID, convene study sections to review a revision application.


Grantees with questions should contact the appropriate program officer or grants management specialist. For more information, read Communicating With NIAID—How to Get Help.
