Dimensie has been the study association for Psychology and Educational Sciences & Technology at the University of Twente since the 30th of November 1981. On the 7th of September 2015, it was decided to make Dimensie the study association for Psychology only.
Dimensie offers her members the possibility for personal development and support within and outside of the study. Furthermore, Dimensie organizes study-related activities like lectures, excursions, a work field day, and a symposium. Dimensie also organizes leisure activities to help bring members into contact outside of classes in a more informal way.
