CPD Value: 36 hours


The supervision and assessment process Our training process is designed to cover the ‘head’, ‘heart’ and ‘hands’ of ACT. We will, therefore, assess your practice of ACT from the perspectives of knowledge, personal experience and skills. Course requirements*:


  • 90mins fortnightly supervision for 12 months (75% minimum attendance required). Participants present at least one recording per month.
  • To present over the course of the training, 240mins of rated audio excerpts (each 20mins in length), including beginning, middle and ending phases of your ACT practice, with at least 4 clients.
  • Final assessment consists of 1) showcasing your latest ACT work in three 20min audio recordings of beginning, middle and ends phases respectively, 2) Answering short essay questions in a written exam, and 3) Submitting a 2000 word journal containing insights along the path of applying ACT to yourself, as well as pivotal moments in your development as a practitioner.

Supervision to start after Intermediate level of ACT is completed.

Completing the training modules without the supervision and assessment process leads to certificates of attendance for each training module completed, and a certificate to summarise all the modules completed on our training programme.
