Science and Technology Policy Institute Originally created by Congress in 1991 as the Critical Technologies Institute and renamed in 1998, the Science and Technology Policy Institute is a federally funded research and development center sponsored by the National Science Foundation and managed by RAND. The Institute's mission is to help improve public policy by conducting objective, independent research and analysis on policy issues that involve science and technology. To this end, the Institute: Supports the Office of Science and Technology Policy and other Executive Branch agencies, offices and councils. Helps science and technology decisionmakers understand the likely consequences of their decisions and choose among alternative policies. Helps improve understanding in both the public and private sectors of the ways in which science and technology can better serve national objectives. The Science and Technology Policy Institute research focuses on problems of science and technology policy that involve multiple agencies. In carrying out its mission, the Institute consults broadly with representatives from private industry, institutions of higher education and other nonprofit institutions.
