This chapter concerns the role of art and how artistic expression can challenge dominant constructions of reality. Artistic expression is often encouraged in the socialisation process and this is professionally justified through the models of 'art therapy', 'art education' and 'client-led' or collaborative art practices. The chapter suggests that institutions play a significant part in the constitution of self and others through shared notions of normality and ideal person, with particular reference to institutions for the 'mentally ill' and schools. The Validation Model, by focusing on the inmates of such institutions, goes towards validating them. The Validation Model of arts education encourages a 'stepping out' of preconceived positions. This 'stepping out' process, whilst occurring at institutional sites, is in conflict with their tendential roles in producing 'ideal selves' through 'cure' and 'educational development'.
