The National Academies also serve as public policy advisors, research institutes, think tanks, and public administration consultants on issues of public importance or on request by the government.The National Research Council, National Academy of Engineering, and National Academy of Medicine began as activities of the National Academy of Sciences until they were reorganized in 2015 into units of the current National Academies while maintaining the charter status and corporate successorship of the original National Academy of Sciences.
