This article is aimed at organisers of courses for the Royal College of Psychiatrists' membership examinations (MRCPsych) and College tutors preparing trainees for the MRCPsych. Running revision courses requires planning and a good deal of work but should be possible for most MRCPsych preparation courses. The theoretical background of assessments is explained. An overview of the type of examination used in the MRCPsych is provided and advice as to how trainees can best prepare for them given. Advice is given on the recruitment and retention of examiners for mock clinical exams, how to deal with simulated patients and what equipment is useful to buy for the use of trainees. We also explain how trainees can practice for the written papers and how feedback is best given to them. The new MRCPsych formal examination and workplace-based assessment programme are also discussed.
