Professional Diploma in Supervision

Open for applications for 2025…

Entry Requirements

This Professional Diploma Course is open to fully accredited psychotherapists/counsellors who have a minimum of four years clinical experience (post-accreditation) and who are working, or beginning to work, as supervisors of psychotherapists/counsellors. Participants are required to have at least one supervisee (not a course member) by the start of the course and to have completed 25 hours of supervision with their supervisee(s) before successful completion of the course.

Course Content

The contents of the course will be drawn principally from the work of Val Wosket and Steve Page, whose book “Supervising the Counsellor: A Cyclical Model”, is the core study text for the course. This model provides participants with a comprehensive and systematic approach to the theory and practice of supervision, while accommodating within it other approaches to supervision.


Course Structure

The course runs over 12 months, amounting to 140 hours of training between January and December each year. The programme includes an Induction day in January, 6 training weekends (Saturday and Sunday, full days) and a one-day clinical seminar, as well as directed study, assignment work and external supervised practice.

Each course weekend includes:

  • Theory input/workshop presentation
  • Supervised skills practice
  • Group supervision (by tutors) of supervision practice undertaken outside of course


Assessment is ongoing during the course and includes both theoretical and practical elements:

  • Live practical assessment of supervision competence
  • Written case study assignment on the theory and practice of supervision


Participants who successfully complete this training programme are awarded the Dublin Counselling & Therapy Centre Professional Diploma in Supervision
