Working professionally and professional behaviour are important issues in the practice of a medical profession. The Radboud University Nijmegen Medical Centre’s Dental School recognizes their importance. The aims of the education in professionalism are that a student’s professional behaviour can be seen to be improving during the study, that the student can reflect on his professional behaviour and that the student, working in a dental team, is able to deal with other people’s responses to his professional behaviour. During the entire study, a ‘Developmental plan of professional behaviour’ is recorded digitally. This developmental plan is discussed and if necessary aspects requiring improvement are indicated.
