Co-ordination screening for children with and without moderate learning difficulties: further experience with Gubbay's tests.
Modified Gubbay tests, assessing various aspects of motor performance, were administered to 885 Manchester children in mainstream primary education, and centile tables were drawn up by age. Children who had performed badly on one of the four tests were retested two years later, when they were found to have 'caught up' with controls. The primary-school children reached a ceiling in their performance by the age of nine or 10 years. A further 482 children, aged eight years to 16 years 11 months and attending schools for children with moderate learning difficulties, were assessed. These children showed continuing improvement up to the age of 14, after which little further improvement was seen. Thus this ceiling occurred some five years later than for the children in mainstream schools. On the more complex tests performance was worse than would have been predicted by general intelligence. Implications for policies of integration into mainstream schooling are discussed.
