The purpose of the study was to assess the relationship between students’ perception of course/ block coordinators performance and attributes with students’ assessment scores in respective courses. This retrospective data based study was conducted at the College of Medicine, King Saud bin Abdulaziz University of Health Sciences [KSAU-HS] . It was started in March 2013 and completed in June 2013 after the graduation of the fourth cohort. Exam score of 3rd and 4th cohort of students from the courses taught in the last two years of medical school were correlated with faculty and block evaluation done by the students. Scores from mid-block MCQs, portfolio scores, OSCEs and end-of-block MCQs were obtained. The Mean scores of all the assessments for all five blocks were not significantly different for both batches. There was significant difference between block coordinators for students’ score on portfolio, midterm exam and the final written exam. The students’ Score in OSCE had significantly strong correlation with quality of station monitors, coverage of content and flow between stations. Student’s perception of the commitment and motivation of the coordinator was strongly correlated with block organization, availability of clinical cases, performance of block coordinator, cooperation with students, and organization of clinical activities. Block coordinator’s motivation and commitment affects quality of block organization and student’s success. Faculty training programs should include block management competencies and components identified through self-determination theory for improving the intrinsic motivation for students success
