This article is written from the perspective of a practising headteacher in the context of the Leadership Programme for Serving Headteachers and addresses the issue of how such training might be appropriated. It seeks to inquire analytically and critically into the bias of the programme, with a special interest in the topic of personal growth and spirituality in leadership development. First, it advocates deploying Hodgkinson's taxonomy of administrative process as a means of analysing the administrative bias of LPSH in relation to the official headteacher characteristics it legitimates. This leads into deeper investigation of the ideological bias of LPSH in relation to the construction of self. Finally, it takes an ambivalent stance on personal growth in professional development, situating it negatively in relation to the tendency of LPSH to promote the dominance of only one personality-type and positively in relation to appreciating spirituality in leadership.
