PASS 3 was used to evaluate 14 residential services for people with me
ntal retardation. Residents had a broad range of abilities. Size of re
sidences ranged from one to seven residents. PASS scores were generall
y associated with both resident's ability level and smaller size of li
ving unit, Overall, the residences were shown to be well-located and r
easonably home-like. However, residence personnel tended to lack organ
ized means and competencies to promote resident development and experi
ence. Administrative practices were also weak. Attention must be given
to factors other than residence size, location, building characterist
ics, and staffing parameters when services are commissioned and when s
ervice contracts are specified and reviewed.
