Using the five-stage model of skill acquisition originally proposed by Dreyfus and Dreyfus (1986), this study investigates the professional development of Rehabilitation Workers (RWs) in the UK through analysis of their practice in training people with a vision impairment in the area of orientation and mobility. From interviews with RWs a clearer picture has emerged of the lack of professional development opportunities and the access to the knowledge of others required to facilitate progression from Novice to Expert in this specialized profession.
