The Global Go To Think Tank Index Report is the result of an international survey of over 1,950 scholars, public and private donors, policymakers, and journalists who helped rank more than 6,500 think tanks using a set of 18 criteria developed by the TTCSP. TTCSP examines the evolving role and character of public policy research organisations.

Over the last 30 years, TTCSP has developed and led a series of global initiatives that have helped bridge the gap between knowledge and policy in critical policy areas such as international peace and security, globalization and governance, international economics, environmental issues, information and society, poverty alleviation, healthcare and global health. These international collaborative efforts are designed to establish regional and international networks of policy institutes and communities that improve policy making while strengthening democratic institutions and civil societies around the world.
