Art therapy is the therapeutic use of art making, within a professional relationship, by people who experience illness, trauma, or challenges in living, and by people who seek personal development. Through creating art and reflecting on the art products and processes, people can increase awareness of self and others, cope with symptoms, stress, and traumatic experiences; enhance cognitive abilities; and enjoy the life-affirming pleasures of making art.

Art therapists are professionals trained in both art and therapy. They are knowledgeable about human development, psychological theories, clinical practice, spiritual, multicultural and artistic traditions, and the healing potential of art. They use art in treatment, assessment and research, and provide consultations to allied professionals. Art therapists work with people of all ages: individuals, couples, families, groups and communities. They provide services, individually and as part of clinical teams, in settings that include mental health, rehabilitation, medical and forensic institutions; community outreach programs; wellness centers; schools; nursing homes; corporate structures; open studios and independent practices.

The American Art Therapy Association, Inc. (AATA) sets educational, professional, and ethical standards for its members. The Art Therapy Credentials Board, Inc. (ATCB), an independent organization, grants credentials. Registration (ATR) is granted upon completion of graduate education and post-graduate supervised experience. Board Certification (ATR-BC) is granted to Registered Art Therapists who pass a written examination, and is maintained through continuing education. Some states regulate the practice of art therapy and in many states art therapists can become licensed as counselors or mental health therapists.
