The article focuses on a 2-year follow-up study of children with motor coordination problems identified at school entry age. Children attending primary schools in Leeds, England, were tested soon after school entry with the Standardized Motor Test Battery (SMTB), specifically designed for this study and comprising: finger tapping, peg moving, bead threading, standing on one leg, hopping and walking. Norms of motor performance are provided for each test. Seventeen children failed the SMTB and were designated to the clumsy group and then matched for age and sex with a control group of children from the survey. Observations by parents and teachers rated the clumsy children inferior to their controls in writing, sporting ability and clumsiness.
