Art-based techniques in counselor and therapist supervision are couched within a constructivist educational and supervision framework. A rationale for artmaking by supervisees within supervision settings is provided, followed by a discussion of various art-based supervision techniques targeted at instilling the capacity for reflection in supervisees, and at increasing supervisees' self-awareness, including case conceptualization skills and processing of countertransference. Art techniques effective in reducing supervisee stress are also introduced. A discussion of the ethical concerns intrinsic in this sort of work, as well as some caveats regarding the introduction of art activities in supervision with non-artist supervisees concludes the article.
