While focus on quality in Danish higher education has been growing in recent years, limited attention has been devoted to developing and thoroughly validating instruments that allow collecting data about university students' perceptions of the teaching-learning environment. Based on data from a large sample of Danish university students, a Danish version of the Learn questionnaire was validated using confirmatory and exploratory factor analysis. Analyses confirmed the existence of three scales reflecting students' approaches to learning and six scales reflecting students' perception of the teaching-learning environment. The results suggest that the Danish version of Learn is a valid instrument to be used for evaluation of the teaching-learning environment as well as for research into Danish university students' learning strategies.
