The PI of an active NSF award may request supplemental funding for one or more graduate students to gain knowledge, skills and experiences that will augment their preparation for a successful long-term career through an internship in a non-academic setting, including the following: For-profit industry laboratories or industry research and development groups; Start-up businesses, such as (but not limited to) those funded through the NSF’s Small Business Innovation Research (SBIR) program and Small Business Technology Transfer (STTR) program; Government agencies (all levels) and National Laboratories; Policy think-tanks; and Non-profit organizations. PIs are encouraged to discuss with the cognizant NSF program director activities that are synergistic with the project scope. It is expected that the graduate student and the PI on the NSF grant will work together to identify innovative experiences that add the most educational value for the graduate student on activities that are not already available at the student’s academic institution. Further, it is expected that the internship will be on-site at the host organization and will be research-focused in a STEM field or in STEM education research. The total amount of funding requested must not exceed $55,000 per student per six-month period. NSF plans to fund up to approximately 200 supplements in fiscal years FY 2019 and FY 2020, depending on the availability of funds. Supplemental funding requests may be submitted at any time but no later than May 1, 2019 (for available FY 2019 funds) and May 1, 2020 (for available FY 2020 funds).
