Mentoring has been present within surgical training for many years, albeit in different forms. There is evidence that formal mentoring can improve patient outcomes and facilitate learning and personal growth in the mentee. The Association of Surgeons in Training (ASiT) is an independent educational charity working to promote excellence in surgical training. This document recommends the introduction of a structured mentoring programme, which is readily accessible to all surgical trainees. A review of the available evidence e including an ASiT-led survey of its membership e highlights the desire of surgical trainees to have a mentor, whilst the majority do not have access to one. There is also limited training for those in mentoring roles. In response, ASiT have implemented a pilot mentoring scheme, with surgical trainees acting both as mentors and mentees. Based on the existing literature,survey data and pilot experience, ASiT formalises in this document consensus recommendations for mentoring in surgical training
