The TestDaF-Institut belongs to g.a.s.t. (Society for Academic Study Preparation and Test Development), a registered non-profit association, and is affiliated to the University of Hagen and the Ruhr-University Bochum. Core tasks of the TestDaF-Institut include the development, implementation and evaluation of the TestDaF (Test of German as a Foreign Language). The TestDaF is used for admissions purposes at institutions of higher education in Germany; it is part of the exam suite of the Goethe-Institut. Approximately 45,000 candidates per year take the TestDaF in order to provide evidence of their language skills. Further tests offered by g.a.s.t. are the onSET, an internet-delivered test system for measuring the level of general language proficiency (German, English) and the TestAS (Test for Academic Studies), a scholastic aptitude test used by universities to assess the suitability of candidates for studies of higher education in specific subjects.
