In June 2005 it became mandatory for psychiatric trainees to receive training directly from people who experience mental health problems and their carers. This will be checked on approval visits to all training schemes, and accreditation may be withheld until this aspect of training is in place. For many of those who are responsible for training, this may be a new undertaking. We outline some of the issues that trainers need to consider when involving service users and carers in their training programmes, including background issues, how to prepare both those delivering and those receiving training, and logistical considerations. It is hoped that this paper will alert trainers to issues that need to be considered if such training is to be successful.
