The movement to increase the number of group home programs for the mentally retarded/developmentally disabled is present in the state of Oregon. The Boundary Street group home, located in Portland, was established as a result of this movement. As a rather typical group home program, it is subject to many of the program concerns and evaluation needs experienced by similar services. This point represents the ultimate reason for this paper. The primary purpose will be to develop a program evaluation system that will be appropriate and beneficial in meeting the evaluation needs of the Boundary Street group home. Because the Boundary Street group home is similar in principle and design to other group homes in Oregon, a second purpose of this project will be to develop an evaluation system that can be beneficial to other programs.
