Supplements are mechanisms to continue a sponsored project with more time and money awarded. A supplemental proposal may result from increased costs due to modifications in design or a desire to add a closely related component to the ongoing project.
Principal Investigators (PIs) with existing National Science Foundation or National Institutes of Health-funded projects may request supplemental funding from these organizations
NSF Supplemental Funding
Supplements can be made under an existing NSF award or within a proposal for a new or renewal NSF award. Interested PIs should consult with the Program Director of their particular NSF award to investigate the potential for the following supplements:
- Research Experiences for Undergraduates (REU) - Supplements
- Research Experiences for Teachers (RET) in Engineering and Computer Science - Supplements
- Veterans Research Supplement (VRS) Program - Dear Colleague Letter
- Career-Life Balance Initiative (includes CAREER, GRFP, and Postdoctoral Supplemental Funding Requests)
NIH Supplemental Funding
Administrative supplemental funds are available to cover costs unanticipated at the time of application submission (e.g., failure of essential equipment, increased costs of analyses). The requested supplement budget cannot exceed $150,000 in direct costs, must be completed within the approved project period of the parent award, and stay within the original approved scope of the parent award. PIs are encouraged to discuss eligibility for administrative supplemental funds with their NIH program officer.
