HiArt Psychotherapist here- from art background. An art foundation is not a foundation degree as some are suggesting. It is the bridge between A level and an art degree. It is necessary to try out different art areas before settling on choice of degree- eg fine art, printmaking, graphics, illustration, animation, sculpture, ceramics, fashion, textile. It is unlikely though not impossible that an A level portfolio would meet the entry requirements of any arts degree. I can’t comment on art/psychology.In terms of art therapy training- you will require work experience in a healthcare area with vulnerable people, for a year, or part time equivalent- before applying. You cannot do the course without this experience.This is the bare minimum, many entrants have worked in mental health for many years before applying. I had 10 years experience! There are very few jobs outside of London- most work is part time or self employed/ precarious. The training was previously limited to those over 25 years old- but that had been lowered over the last few years. It was often the case that those applying had life experience/ not simply age-of using art to reconcile feelings around difficult or adverse life events. Many of the courses expect an understanding of art process/ product and what you understand it to say about you- they are not interested in quality of work - more that you have an understanding of how art is connected to internal self. It’s worth doing a foundation in art therapy also to gain this understanding.The only route to art therapy is via an MA course that leads to HCPC regulation ( the titles art therapist and art psychotherapist are protected by law), so someone studying art could not then do a counselling course or psychology course and practice as an art therapist- this would be illegal in the UK. Hope that helps !
