The paper reviews research and experience in human service integration and examines the impact of federal grant consolidation upon services for the disabled. Reasons for the existence of categorical aid are noted. An idealized integrated services system is proposed, and factors such as excessive red tape and lack of coordination which reflect a need for service integration, the impact of "new federalism," recent federal initiatives, state umbrella agency/services integration experiences, and attitudes of agency executives on services for the disabled are considered. Five questions are posed regarding the value of integration in the disability field. The questions touch on resource allocation goals, state and local expectations, professional and consumer roles, amelioration of administrative problems, and sufficiency of knowledge. (CL)
