[Causes of school inadaptation in children. Detection in nursery schools and course]

Eight hundred and ninety, 3 year-old children attending public kindergarten of the Ille-et-Vilaine district were closely followed till the end of the first primary school year. 44.07% presented with one or several troubles for which prevalence and associations are detailed. 4.7% presented with 4 or more associated troubles. School life was not influenced by eyesight (14.5%) and hearing (4.4%) impairment because they were fairly often corrected. Motricity, speech and behavioural dysfunction seemed to be the most important prognostic factors: 2.1% of the children stay down the 3rd year of kindergarten and 9.7% the first year of primary school. The influence of socio-economic environment was obvious, both for the prevalence of troubles and for the school performances. This study suggests that current management of these problems should be improved.
