The purpose of this study was to identify the incidence of Developmental Co-ordination Disorder (DCD), (American Psychiatric Association, 1987) in the county of Gwynedd and design, carry out and evaluate an intervention programme with a sample of the children identified as having DCD. Some children appear physically and intellectually normal yet lack the motor competence necessary to cope with the demands of everyday living (Gubbay, 1975; Henderson and Hall, 1982). This lack in motor competence or Developmental Co-ordination Disorder affects 6% of children in mainstream primary education (Peters, 1995). Recent longitudinal studies of such children have shown that the difficulties that these children face are not transitional and not devoid of personal, social and educational consequences (Henderson and Barnett, 1996). A random sample of 7-8 year olds, (n=l 83), were assessed using the Movement Assessment Battery for Children (Henderson and Sugden, 1992). 5.8% (n=l 1) children were identified as being at 'risk' and a further 5.8% (n=l l) children were in the 'borderline' category. Subsequently, from these two groups, 8 children were included in an intervention programme. The intervention programmes were based on a cognitive motor approach and were individually designed to meet the needs of each child. A single case study multiple baseline design was adopted to evaluate the intervention programme and the data was analysed using the SPSS 6.1 statistical package. The effects of the intervention programme was evaluated on an individual basis and on the group as a whole overall indicating the positive effect of the intervention programmes (p
