Abstract
This article describes the development and use of a formal training tool for restoration of competency in clients with mental retardation who are incompetent to stand trial. The program was developed at Eleanor Slater Hospital within the Rhode Island Department of Mental Health, Retardation and Hospitals. This article describes the development of The Slater Method, the training tool format, the procedure for use of the Slater Method, and the duration of treatment to restore competency to stand trial in clients with mental retardation. Although the developmentally disabled population is not limited to persons with mental retardation, we have used the phrase mental retardation instead of developmentally disabled because the judicial system more commonly uses mental retardation.
