Students' perceptions of their educational environment have been studied at all levels of the education system, from primary through post-secondary education. Recent imperatives towards enhanced quality assessment monitoring at a time when health professions education is increasingly committed to student-centred teaching and learning have stimulated a revival of interest in this field. This paper reports a body of research in health professions institutions around the world based on the Dundee Ready Educational Environment Measure (DREEM), a reliable, validated inventory that claims to be generic to undergraduate health professions education and non-culturally specific.
