From 2017 to 2020, the Think Tank Hub, in collaboration with On Think Tanks (OTT), organised the WISCH – WinterSchool for Thinktankers. WISCH was a seven-day intensive course with lectures and guided group work for young and proactive individuals who are eager to develop their knowledge and understanding of think tanks and to prepare themselves to become future policy entrepreneurs. It offered practical skills, opportunities and networks to help think tanks grow in core areas such as fundraising, communications, financial management, policy engagement and more.
