Office of Science and Technology Policy (OSTP): History and Overview [Updated October 8, 2019] [open pdf - 1MB]
From the Document: "Historically, advice to the President was provided through advisors and boards without statutory authorities. Congress moved in 1976 to codify a formal mechanism for presidential science advice. The National Science and Technology Policy, Organization, and Priorities Act of 1976 (P.L. 94-282) established the Office of Science and Technology Policy (OSTP), including the position of its Director, within the Executive Office of the President (EOP) to provide scientific and technological analysis and advice to the President. This act codified and institutionalized a presidential science advice function that previously existed at each President's discretion. This report provides an overview of the history of science and technology (S&T) advice to the President and discusses selected recurrent issues for Congress regarding OSTP's Director, OSTP management and operations, the President's Council of Advisors on Science and Technology (PCAST), and the National Science and Technology Council (NSTC)."
