Purpose
Peer assessment is recognized as a valuable tool for promoting professionalism in medical education. It encourages students to reflect on their behavior, communication skills, and teamwork. Studies have shown that peer evaluation contributes to the development of interpersonal skills and professionalism, enhancing students' ability to work collaboratively in healthcare settings.

Methods
We developed a uniform peer assessment criterion where peer evaluation and reflection are conducted seven times across the pre-clerkship phase. Students evaluate the performance of their team members and provide meaningful and actionable feedback. The receiving student then reflects on the provided feedback. Team members receive feedback on professionalism, teamwork, interpersonal skills, and communication skills.

Results
Preliminary data was collected from four peer evaluation occurrences involving 240 first-year (M1) and second-year (M2) students. The most valued behavioral attribute across M1 and M2 was ‘contribution to the group process,’ followed by being ‘well prepared, truthful, and dependable.’ Sharing information, resources, and helping others learn was the third most valued attribute. The most important attribute for improvement was maintaining a good balance of active listening and participation.

Conclusions
A consistent pattern of valued behaviors and attributes was observed between different peer groups and across years. Similarly, consistent patterns were observed in areas for improvement. Next steps include demonstrating improvement in the identified areas based on feedback and maintaining a consistent pattern of valued attributes and behaviors in a randomly selected sample of students.
