An audit project has been submitted by all trainees in the West of Scotland since 1992 as part of a pilot process for summative assessment. The impact of 2 consecutive years of audit was assessed on 117 trainees in May 1994. A response rate of 89% was achieved. For 82 trainees (79%) this was their first practical experience of audit and as a result of it 85% felt more confident in introducing change to their next practice. Protected time was still a problem for the majority (53%) and one-third wanted more help from their trainer. Thirty trainees (29%) had attended four or fewer formal practice meetings in their 10 months of training, with 10% never having attended one. The previous trainee's audit project was rarely or never discussed with 70 trainees (87%) and only 12 trainees were evaluating changes recommended. An audit project as part of summative assessment may be encouraging trainees to think about change after they leave their training practices. Few, however, are evaluating change and protected time and support are still required. The marking of the summative assessment audit project may need to address this.
