In comparison to many other funding organisations, WWTF has a call/jury system to select projects. This means, a certain budget is dedicated to a specific call, which cannot be exceeded even if there are more projects that would be qualified to be funded. The decision about the proposals based on their scientific content is exclusively made by an international expert jury. The jury is composed with the help of WWTF’s boards and members of the call jury are selected specifically with regard to the thematic requirements of the call. Members are highly qualified and renowned experts of the international scientific community. WWTF does not include experts with an Austrian affiliation.
