Frequently Asked Questions
The most commonly used grant mechanisms are the Research Project Grant (R01), Small Research Grant (R03), Exploratory/Development Grant (R21), and the Research Program Project Grant (P01). In addition, all grant mechanisms that use the electronic submissions process are acceptable. View NIH's complete list of eligible grant mechanisms.
Yes. A request to change an active award from a single-PI to a multiple-PI model, or from a multiple-PI model to a single-PI model, during the non-competing year, must be made by the grantee organization and should be based on the scientific needs of the project as described in NIH-NOT-OD-11-118.
Yes. With appropriate justification, such changes are possible; however, the prior approval of the funding IC must be sought by the Authorized Organization Representative. In addition to a written scientific justification for the change as, the following must be included in a formal request to change or add a PD/PI on a multiple PD/PI award: biographical sketch of the PD/PI(s) to be added and information on other sources of support, any budgetary implications of the changes, any proposed changes in scope, and an updated leadership plan.
Yes. You will no longer be classified as a New Investigator unless all the PIs are also New Investigators.
No. When multiple PIs are proposed, NIH requires identification of one PI who will be designated as the "Contact PI." This person will be responsible for communication between the PIs and NIH, but has no special authorities or responsibilities within the project team. In many ways, a Contact PI is analogous to a corresponding author on a publication.
The Contact PI must serve as a real PI and must meet all eligibility requirements for PI status. Where there is an identified project coordinator, the coordinator could serve as Contact PI or that role could be assigned to another PI. It will be possible, and may be desirable, for the grantee institution to periodically designate a change in Contact PI. For example, it may be desirable to rotate the role of Contact PI among the multiple PIs on an annual basis at the time of grant renewal.
All PIs have equal responsibility and accountability for leading and directing the project. The structure and interaction of the PI team will be left up to the PIs and the applicant institution. All PIs must be qualified to serve as PIs and will share responsibility for the project.
Although the PIs may identify a leader of the project or a coordinator of the overall team, that role is not formally acknowledged by NIH. Smaller teams composed of PIs of equal rank within the institution may function best as an equal partnership without an identified coordinator. If any team believes it necessary to identify a spokesperson or coordinator responsible for organizing the leadership team of a particular project, that role and rationale should be explained in the Leadership Plan.
PIs must meet the definition of a PI as determined by their institutions. Only the applicants' institutions can decide who should be a PI. Peer reviewers will consider whether the designated PI has the appropriate training and experience to carry out the proposed research, which is standard practice in peer review.
