This article aims to introduce five models of dealing with the self-concept applied by individuals in the process of personal and professional development and the method of using these models in the context of coaching or mentoring. The experience of using this method is discussed and suggestions are made for those who would like to adopt it for enriching their practice. The article draws practitioners’ attention to the broader picture of their interventions in relation to individual developmental strategies and the implications that these have for the coaching and mentoring relationship.
