Learning environment is found to be important in determining students’ academic success and learning. The goal of this study was to investigate the viewpoints of medical students toward learning environment based on The Dundee Ready Education Environment Measure (DREEM) at Rafsanjan University of Medical Sciences (RUMS). This descriptive study was conducted using the Persian DREEM questionnaire. All medical students in basic and clinical courses except internship students (fifth and sixth year) were approached to participate during the study period, of which 223 provided consent and completed the survey. Data were analyzed by SPSS-17, t-test and ANOVA statistical tests were used. The mean total score was 113.8±17.31 (out of a maximum of 200, 56.9%) indicating relative satisfaction with the perceived environment.
