National strategies for the development of services for specific client groups are rare in Britain, particularly strategies to which governments pledge significant long term financial investment. This paper attempts to guage the impact of one such strategy, the All Wales Strategy for the Development of Services for Mentally Handicapped People (AWS) (Welsh Office, 1983) by comparing the goals of the AWS with changes in the nature and coverage of services which have followed its inception. Data on the provision of residential, day, education and family support services in Wales were collected in 1995 from county annual plans, Welsh Office statistical returns and questionnaires to county officers. These sources were cross referenced and the data compared with those reported in a companion paper (Beyer et al., 1991) for 1983 (the first year of the AWS) and 1988. Between 1983 and 1995, deinstitutionalisation accelerated, residential services were reprovided by combined statutory and independent sector action, size of residential settings reduced considerably, the range of day activities diversified, mainstream education was available to more children with learning disabilities, respite care became largely community based and the availability of domiciliary support increased significantly. Although the pace of change quickened between 1988 and 1995 compared to that in the first five years of the AWS, a wholesale reorientation of traditional services is far from complete. Changes in service provision in Wales during the course of the AWS are compared where possible to development elsewhere in Britain.
