<p>Abstract</p> <p>Background</p> <p>Development of students' teaching skills is increasingly recognised as an important component of UK undergraduate medical curricula and, in consequence, there is renewed interest in the potential benefits of cross-year peer tutoring. Whilst several studies have described the use of cross-year peer tutoring in undergraduate medical courses, its use in the clinical setting is less well reported, particularly the effects of peer tutoring on volunteer tutors' views of teachers and teaching. This study explored the effects of participation in a cross-year peer tutoring programme in clinical examination skills ('OSCE tutor') on volunteer tutors' own skills and on their attitudes towards teachers and teaching.</p> <p>Methods</p> <p>Volunteer tutors were final year MBChB students who took part in the programme as part of a Student Selected Component (SSC). Tutees were year 3 MBChB students preparing for their end of year 'OSCE' examination. Pre and post participation questionnaires, including both Likert-type and open response questions, were used. Paired data was compared using the Wilcoxon signed-rank test. All tests were two-tailed with 5% significance level.</p> <p>Results</p> <p>Tutors reflected their cohort in terms of gender but were drawn from among the more academically successful final year students. Most had previous teaching experience. They were influenced to participate in 'OSCE tutor' by a desire to improve their own teaching and associated generic skills and by contextual factors relating to the organisation or previous experience of the OSCE tutor programme. Issues relating to longer term career aspirations were less important. After the event, tutors felt that participation had enhanced their skills in various areas, including practical teaching skills, confidence in speaking to groups and communication skills; and that as a result of taking part, they were now more likely to undertake further teacher training and to make teaching a major part of their career. However, whilst a number of students reported that their views of teachers and teaching had changed as a result of participation, this did not translate into significant changes in responses to questions that explored their views of the roles and qualities required of a good clinical teacher.</p> <p>Conclusion</p> <p>Findings affirm the benefits to volunteer tutors of cross-year peer tutoring, particularly in terms of skills enhancement and reinforcement of positive attitudes towards future teaching responsibilities, and have implications for the design and organisation of such programmes.</p>
