The aim of the present study was through semi-structured interviews to explore "udeskole" teacher's perceptions of motivational factors and challenges while teaching regularly outside the classroom on a weekly basis during a year. Six females and two male "udeskole" teachers participated and answered an interview guide containing five themes about their motivations, student relations, teaching experiences, challenges and recognition. "Udeskole" was perceived to have substantial potentials to improve both academic learning and life skills and 'the common third', i.e. teacher-pupil relations, was mentioned as a value added to the indoor teaching. Health and safety issues were not perceived as barriers.
