The University of Hagen (German: FernUniversität in Hagen, informally often referred to as FU Hagen) is a public research university that is primarily focused on distance teaching. While its main campus is located in Hagen, North Rhine-Westphalia, Germany, the university maintains more than 50 study and research centers in Germany and throughout Europe. According to the Federal Statistical Office of Germany, it is Germany's second-largest university. The university was founded in 1974 as a public research university by the state Nordrhein-Westfalen and began its research and teaching activities in 1975. It was founded following the idea of UK's Open University to provide higher and continuing education opportunities through a distance education system in Germany.
The university awards the same qualifications as other German on-campus universities and maintains the same requirements. Initially, the university had only three faculties with 1,304 full and part-time students, but today the university has developed into Germany's leading institution for distance education and is the only full university in that field with a student body of 83,536 students in the summer term of 2013 and 86,889 students in the winter term 2013/14. Besides the substantial number of off-campus students, a considerable number of full-time postgraduate research students as well as more than 1,800 members of academic and research staff are based on the University of Hagen's main campus in Hagen.
