approach to or emphasis within mental health versus the prevailing "medical" model. Glasser founded the Institute for Reality Therapy in 1967, which was renamed the Institute for Control Theory, Reality Therapy and Lead Management in 1994 and later the William Glasser Institute in 1996 in Chatsworth, CA. The institute is now located in Tempe, Arizona, and has branch institutes throughout the world. By the 1970s Glasser called his body of work "Control Theory". By 1996, the theoretical structure evolved into a comprehensive body of work renamed "Choice Theory", mainly because of the confusion with perceptual control theory by William T. Powers, developed in the 1950s. Reality therapy organizations In the United States, the Glasser Institute was originally organized with regional groups in New England, the Sunbelt, the Northwest, the Midwest, the Southeast, and the West Coast. In July 2010 the William Glasser Association International (WGAI) was established in Nashville, Kentucky, with an interim governing board charged with setting up the organization to coordinate worldwide activities and conferences, the first of which was in 2012 in Los Angeles. The board eventually became incorporated in California under the new name of William Glasser International (WGI) and is the umbrella body recognised by Glasser to represent his ideas around the world. The members of the WGI Board are elected by members. Outside of the United States, William Glasser International (WGI) has active affiliate organizations in many countries including Canada, Croatia, Slovenia, Ireland, the UK, Finland, Malaysia, the Philippines, South Korea, Japan, Central and South America, South Africa, Australia and New Zealand. Neither WGI nor its affiliate organisations confer titles such as "counsellor" or "therapist" in their regular certification courses. In Europe, however, there are two special courses offering by the European Institute for Reality Therapy, one leading to the title Reality Therapy Psychotherapist and the other to obtain the title Reality Therapy Counsellor. Both can lead to The European Certificate in Psychotherapy (ECP). The William Glasser Institute UK (formally Institute for Reality Therapy UK), with its own administration executive, coordinates the faculty workshops and practicums in the United Kingdom on behalf of WGI International, leading up to and including Reality Therapy Certification (CTRTC).
