The recent much needed increase in the provision of evidenced-based psychological interventions, such as cognitive behaviour therapy (CBT), has created a demand for suitably trained and competent CBT supervisors in the UK. Simple training for this role is inadequate, so novice supervisors should also consider working with an experienced supervisor, having their supervision practice observed and seeking regular feedback on their supervisor competence. This encourages self-reflection and builds competence in supervision, which can lead to formal accreditation with the British Association for Behavioural and Cognitive Psychotherapies.
