NIH Grants Policy Statement
Revised October 2017. This document applies to all NIH grants and cooperative agreements for budget periods beginning on or after October 1, 2017.

9.1 General

Multiple Program Director/Principal Investigator (multiple PD/PI) awards are an opportunity for multidisciplinary efforts and collaboration through a team of scientists under a single grant award. All PD/PIs share equally the authority and responsibility for leading and directing the project, intellectually and logistically. Each PD/PI is responsible and accountable to the applicant organization, or as appropriate to a collaborating organization, for the proper conduct of the project or program, including the submission of all required reports. The presence of more than one PD/PI on an application or award diminishes neither the responsibility nor the accountability of any individual PD/PI. The applicant/recipient organization is responsible for securing and retaining the required written assurance signatures from each identified PD/PI on all applications, post-submission information, progress reports, and post-award prior approval requests and must make these signatures available to NIH or other authorized DHHS or Federal officials upon request.

NIH implementation of Multiple PD/PIs is in accordance with the January 4, 2005 Office of Science Technology Policy directive to Federal research agencies.
