I recenlty am on the verge of finishing an access to combined studies course and been accepted onto a foundation degree in health and social care, i plan to also take a GCSE class in Art. My plan is to then use this to spear off onto MSc in Art therapy. Am i taking the right course of action.

According to the NHS, you should hold a first degree in Art or a related subject then followed by a postgraduate degree in Art Therapy. I have included the link to this page so you can read it yourself. Also I have included the link to the NHS course finder so you can search for an art therapy degree aswell as the link to the Jobs4U Art Therapist bit.

I hope this all helps you!
Also the 1st link has a little bit about alternative qualifications. The nhs careers website has a lot of information about this career. Explore the website as well!
