The supervision of doctoral students has been evolving in the last decade. Supervisors supervise students on campus or at a distance and supervision takes place in formal or informal environments with the latter occurring more often through online encounters. This context of supervision has changed supervisory practices and students' own approaches to learning. This paradigmatic shift demands a rethinking of how supervisors develop themselves and how they learn to cope with the challenges of 'modern' supervision. To date, little has been said or written about the development or training of doctoral supervisors who supervise students online or at a distance. This paper aims to fill this gap by presenting a model for the professional development of supervisors in these contexts. This model can be adapted and implemented by institutions that wish to support supervisors who support students online or at the distance.
