The National Institutes of Health (NIH) supports innovative technology development as one aspect of fulfilling its mission. In July 2014, NIH tasked the IDA Science and Technology Policy Institute (STPI) to develop performance measures for technology development projects. The study had three components. The first was development of a comprehensive catalog of NIH Funding Opportunity Announcements (FOAs) that are focused on technology development for achieving a specific goal. The second was identification of a representative sample of FOAs from the catalog and developing case studies based on discussions with program officers knowledgeable about those FOAs. Finally, STPI identified candidate outcome measures for assessing technology development initiatives, as well as the data collection infrastructure that would be required to implement these measures in a consistent and ongoing manner. This document summarizes the assessment and findings.
