From the 1970s, reforms to government science support drew funding back into departments which had new chief scientists and reduced the role of the
Government Chief Scientific Adviser (GCSA). In order to direct this, a central committee was formed to set priorities for applied research in parallel to the advisory board for the research councils (ABRC) which advised on basic research. The advisory functions now in the CST were performed by the Advisory Council for Applied Research and Development (ACARD), from 1976 to 1987, and the Advisory Council on Science and Technology (ACOST) from 1987 to 1993 which included defence as well as civil research. The CST was formed in 1993 to advise the prime minister, bringing departmental chief scientists into the council and absorbing the ABRC into government. The aim of the CST was set out in a white paper on science policy which recognised the role of government in funding major investments, and working internationally on the largest projects. But it also saw science as driving innovation and economic growth in a partnership with industry, which funded at least half of science. The CST was expected to integrate expertise with the new technology foresight work of the
Office of Science and Technology and advise on the balance of government research. Periodic reviews have been conducted since the CST was formed, most significantly in 2003. The
Royal Society responded to the call for evidence to suggest adopting the independent co-chair model used in the USA. Although the review itself specified two options, an independent chair or the GCSA chairing, the government response chose the co-chair model used today. The 2003 review also saw a change to include wider societal expertise, covering economics, health, and ethics which could better identify policy implications and the extent of the impact of innovation. ==Membership==
