Assessment of oral presentation skills is an underexplored area. The study described here focuses on the agreement between professional assessment and self- and peer assessment of oral presentation skills and explores student perceptions about peer assessment. The study has the merit of paying attention to the inter-rater reliability of the teachers. Comparison of the teacher and peer assessment rubric scores points at a positive relationship, but also at critical differences. The lower intra-class correlation suggests that peers and teachers still interpret the criteria and indicators of the rubric in a different way. With regard to the comparison of self-assessment scores and teacher scores, we have to conclude that there are significant differences between these scores. Self-assessment scores are, for the most part, higher than the marks given by teachers. The results also reflect a very positive attitude of students towards peer assessment as a relevant source of external feedback. (Contains 4 tables and 1 figure.)
