Peer review of third year bioprocess engineering laboratory reports was introduced in an attempt to improve the standard of report writing in the BSc in Biotechnology degree programme at DCU. Preliminary results suggest that the review process leads to improved report writing skills. The student response to the initiative was very positive but it was strongly felt that the process should be anonymous. On average, marks awarded by students were higher than those awarded by the lecturer but there was a slight tendency to award more extreme marks.
