Teaching and mentorship are fundamental parts of registered nurses’ roles, and learning should be managed and promoted in clinical practice to ensure excellence. This article reflects on, and critically analyses, the developing relationship between the author, who is an advanced nurse practitioner (ANP) and practice educator, and an experienced nurse undertaking an ANP level 7 programme of study. The article describes the supervision and mentorship of the student ANP in an emergency department, in the context of the ‘facilitation of learning’ and ‘evaluation of learning’ domains of the Nursing and Midwifery Council (NMC) Standards to Support Learning and Assessment in Practice (NMC 2008).
