Supervision and Mentoring Training Resource is based on the idea that supervision and mentoring can be seen as special instances of collaboration and teamwork. This training resource will help participants understand the value of mentoring, including peer mentoring, and coaching in career development. Another objective of this TR is to maintain collaboration between existing supervisors/mentors and METEOR participants, avoiding conflicting priorities, whilst increasing the quality of supervision and the openness of doctoral education to transversal skills improvement.
