Appeals Process

NIH has two formal appeals processes:

  1. To resolve disagreements between applicants and NIH staff concerning the referral (assignment) or withdrawal of applications prior to review; and
  2. To resolve disagreements between applicants and NIH review committees concerning review of applications. 

Appeals During the Referral Process (before Peer Review)

There are two separate processes to follow, depending on the context. An appeal of the study section or institute assignment (termed a "dispute") before study section review of the application should be sent to the appropriate staff in the Center for Scientific Review (CSR). CSR's Division of Receipt and Referral (DRR) handles the initial referral of applications, and referral/review staff will respond to the letter. 

An appeal of the withdrawal of an application prior to review will be handled by the withdrawing party: either DRR or NIGMS. 

  • DRR:
    • DRR's process and policy should be followed if your withdrawal letter is signed by a Scientific Review Officer or a DRR Referral Officer.
  • NIGMS:
    • If the withdrawal letter is signed by your Program Officer (PO), it will include instructions on how to begin the appeals process by reaching out to your PO. If a discussion cannot resolve the issue, please submit an appeal letter to your PO that includes both the reason for the withdrawal and why you believe the application should be reinstated. 

Appeals of NIH Initial Peer Review

Although procedural aspects of technical merit review are subject to appeal, differences in scientific opinion, such as may occur between applicants and reviewers, may not be contested through the NIH appeals process. Furthermore, as described below, formal appeals (those brought to the National Advisory General Medical Sciences (NAGMS) Council (NAGMSC)) must be based on one or more of four specific issues and include concurrence from the unauthorized organization representative (AOR) from the applicant institution. 

Before beginning the appeals process, the applicant is strongly advised to speak with the NIGMS PO responsible for the application. The PO can explain the options and their consequences and can often help the applicant understand the study section's recommendation. In most cases, issues can be resolved at this stage. 

For cases that cannot be resolved by discussion, the first step in the appeals process is the submission of a formal appeal letter. Appeal letters based solely on differences of scientific opinion will not be accepted. An appeal is a written communication from a program director/principal investigator (PD/PI) and/or applicant institution that meets the following four criteria: 1) is received after issuance of the summary statement and up to 30 calendar days after the second level of peer review (NAGMS Council), 2) describes a flaw or perceived flaw in the review process for a particular application, 3) displays concurrence from the AOR and 4) is based on one or more of the following issues related to the process of the initial peer review:

  • Evidence of bias on the part of one or more peer reviewers.
  • Conflict of interest (COI), as specified in regulation at 42 CFR 52h.5 [PDF] "Scientific Peer Review of Research Grant Applications and Research and Development Contract Projects," on the part of one or more peer reviewers.
  • Lack of appropriate expertise within the review panel.
  • Factual error(s) made by one or more reviewers that could have substantially altered the outcome of review. 

A letter that does not meet these criteria and/or does not include the concurrence of the AOR will not be considered an appeal letter but rather a grievance, and will not necessarily be taken to the NAGMSC. Appeals involving potential COI or violation of ethical conduct rules on the part of an NIH staff member or other federal employee will be referred to the appropriate deputy ethics counselor for consideration and resolution before any further review of or action on the appeal.

An appeal letter submitted after the study section review should be sent to the NIGMS PO. The letter will be shared with the Scientific Review Officer, who will respond in writing to the PO. Program and review staff will try to resolve the issues and take appropriate action. If the issues cannot be resolved by staff, the appeal letter and all relevant information are made available to the NAGMSC, which conducts the second level of review for research applications. Appeals are due 30 calendar days before the applicable Council meeting. Consideration of appeals received after this date may be deferred to the next Council meeting.

The Council may agree with either the study section or the applicant. If the Council agrees with the applicant, it recommends appropriate action to resolve the matter. If a re-review is recommended, the same application, not a revised or updated version, will be re-evaluated. If the Council agrees with the study section, the applicant may decide that submission of a new or revised application is the best option. The PO can often give valuable advice about options. 

The Council's recommendation concerning the resolution of an appeal is final and will not be considered again by the NIH through this or another process. At no time should the PD/PI or an official of the applicant organization attempt to contact individual Council members to discuss the application or appeal, as doing so could jeopardize the confidentiality and integrity of the appeals process.
