Are Teapot Trust’s art therapists qualified? We have 16 professionally qualified and registered art therapists who work on a sessional basis. (That means they’re contractors, not staff.) They all have a Masters degree in art therapy and are registered with both the Health and Care Professions Council and the British Association of Art Therapy. Their hours vary with some working with us just a few hours each week and others doing significantly more. So, although we have 16 art therapists, in practice this equates to just 5 full-time equivalent workers.
