OECD Working Party of National Experts on Science and Technology Indicators

Overview
Since 1962, the OECD Working Party of National Experts on Science and Technology Indicators (NESTI) has been responsible for developing and updating the Frascati Manual, the OECD guidelines for measuring R&D. Frascati definitions and classifications have been widely adopted, including for non-statistical purposes. Over the next couple of years, NESTI will undertake the Manual's sixth revision.
