This paper is a description of one parent teaching group and what we and the parents did. The group was run by a psychologist and two social workers.In Gwynedd a service for mentally handicapped people is developing. For most of the pre-school children and some of the older ones this includes a Portage type home visiting where usually a psychologist and a specialist community nurse or sometimes a social worker visit and help the parents to set goals and teach new behaviour to their handicapped relatives. Often, too, they are trying to help parents to cope with difficult behaviour.
