psychodrama therapists, are often intensively trained and educated to use only one modality in their practice. But NOAH also acknowledged that the terms "are often used interchangeably in the field", and that in any case all such professionals should collaborate closely. The International Expressive Arts Therapy Association (IEATA) is the responsible organization handling the credentialing of expressive arts therapists.
