The WERA-IRN conference Extended Education from an International Comparative Point of View held at University of Bamberg, Germany, in 2017 aimed at bringing together different research perspectives, to synthesize the state of research worldwide in this new field of extended education - afterschool and out-of-school time learning -, and to initiate an international research direction from a comparative point of view. WERA-IRN Extended Education is an International Research Network of the World Education Research Association. From the conference proceedings, thirteen high-quality papers have been selected representing the international state of research on extended education.
