Significant Change of PI or other Key Personnel
Since the approval of the project has, to some degree, been based on the participation or qualifications of the PI and other key personnel, the sponsor requires notification whenever there is to be a significant change in the level of participation in the awarded project by the principal investigator (PI) or other Key Personnel named in the Notice of Grant Award. The sponsor has the option to either approve or disapprove of any proposed alternate plans related to the research.
Significant change in the level of participation may be defined as:
  1. The PI not giving active direction of the project for a continuous period of time greater than three months, e.g. sabbatical leave, or
  2. a 25% reduction in time devoted to the project.
The program officer/Grants Management Specialist at the awarding agency must be notified in a letter signed by the PI and a Signing Official of the Office of Sponsored Programs. The letter should detail the reason for the change in key personnel and provide the replacement PI's biosketch and other support/active pending document. These requests must be made prior to implementing any changes. OSP will make the appropriate changes to award files.
