This paper argues for a pedagogic practice to overcome the challenges that many professional practitioners face in undertaking a professional doctorate. Recent examination feedback on a professional doctoral programme of 300 candidates in the UK highlighted that a number of candidates often struggle to write persuasively, critically and reflectively. This paper discusses the impact of a series of workshops designed to support students in resolving the challenges of writing clearly. In our workshops, we encouraged the students to conceptualise their professional doctorate as a critical autobiography. In order to foster a critical autobiographical voice in our students, we explored a range of autobiographical texts for students to use as models for their own writing. In addition to offering a description of our teaching practice in these workshops, this paper explores the theoretical background that illuminates our pedagogical choices. Both theory and practice are posited side by side in our paper to uncover mutually illuminating connections in our discussion and evaluation of our attempts to improve students' writing. We suggest that conceptualising the professional doctorate as critical autobiography is a valuable tool for professional practitioners who struggle to communicate the complexities of their practice confidently and lucidly.
