The use of lay members on research ethics committees has for some time been felt to be an example of good practice in ethical review processes. In this paper, written by a lay member, the author considers what the recruitment process for lay members might be and argues how this process should largely be shaped by what role the lay member is recruited to undertake. In considering the advantages and disadvantages of lay members, the author shows that defining the role of a lay member is not straightforward but is necessary to the good working of a research ethics committee.
