The purpose of this paper is to outline the background to the introduction of peer assessment at the University of Ulster and to report on how the project has operated and developed over the past three years. Initially assessors were drawn from the same student year group as the performers (BMus, year 2). The process was monitored by the authors who subsequently met with each assessment panel to discuss the performances before marks and reports were finalised. In the following years the assessment of second-year performances was conducted by panels of final-year students; this resulted in more objective reporting.
