From the Report’s Abstract:
The TTCSP works with leading scholars and practitioners from think tanks and universities in a variety of collaborative efforts and programs, and produces the annual Global Go To Think Tank Index that ranks the world’s leading think tanks in a variety of categories. This is achieved with the help of a panel of over 1,796 peer institutions and experts from the print and electronic media, academia, public and private donor institutions, and governments around the world. We have strong relationships with leading think tanks around the world, and our annual think Tank Index is used by academics, journalists, donors and the public to locate and connect with the leading centers of public policy research around the world. Our goal is to increase the profile and performance of think tanks and raise the public awareness of the important role think tanks play in governments and civil societies around the globe.
