The Nursing and Midwifery Council’s (NMC) Standards to Support Learning and Assessment in Practice (2008) outline requirements for the preparation of those who support nursing and midwifery pre-registration students in practice, formally known as mentors. Pre-registration nursing and midwifery programme providers, and practice learning environments (PLEs), work collaboratively to prepare registrants to undertake this role, and to help them maintain mentor status. An important NMC requirement is that registrants, when undertaking mentor preparation programmes, must be supported by experienced mentors in their workplace. This is challenging for programme providers and PLEs if there is lack of experienced mentors in the area concerned. This article discusses support for registrants when preparing to become mentors, suggests some alternative solutions and makes recommendations for the future of mentor preparation in the UK.
