20/20: Consensus Definition of Counseling. The delegates met at the ACA Conference in Pittsburgh in March 2010 and agreed on a unified definition of counseling. Counseling is a professional relationship that empowers diverse individuals, families, and groups to accomplish mental health, wellness, education, and career goals. The delegates made it clear that the definition was a basic framework and that each participating organization is welcome to add a statement that fleshes out the particular specialty or area of focus.
