The Association for Specialists in Group Work (ASGW) supports the practice of ethical and effective group work through the publication of guiding principles in planning, performing and processing group work. Originally prepared, approved and published in 1998 (ASGW; Rapin and Keel), the current revision addresses changes in the American Counseling Association Code of Ethics (ACA, 2005). The revisions were reviewed and approved by the ASGW Executive Board on March 23, 2007.
