The current status of three federally supported construction programs of facilities for the mentally handicapped is reviewed. The programs discussed are designed to provide assistance in the areas of: continuing research into causes and means of prevention of mental retardation, interdisciplinary training of professional personnel, and establishment of community facilities. Research centers operating under the program (P.L. 88-164) are described including location, area of study and funding statistics. University-affiliated facilities for the mentally handicapped set up to provide clinical training of professional personnel are examined. A brief description of each facility reviews the types of facilities and programs which have been supported with the funds and the current status of their construction. Community facilities approved for federal assistance under the construction program are listed by state and pertinent data such as type of facility, services available, retarded served, and estimated costs, are supplied in chart form.
