In recent years there have been major changes in the structure of statistics education at the Faculty of Medicine. A major factor in this change is the increased importance of practical projects evaluated by peer evaluation. In this discussion, I describe my experience of applying peer evaluation in teaching and show results of comparison of peer evaluation and self-assessment on the same projects. The mean score of peer evaluation was 9.1, but the mean score of self-assessment 9.4. Students with lower grades had higher tendency to overestimate their own ability than students with higher grades. Peer evaluation has led to increased quality of assignments and provides students with useful practical training in presentation and interpretation of statistical results. Peer-assessment has been a pleasant experience for both students and teachers.
