ABSTRACT
The results obtained from a year's application of the Social and Emotional Development Scales in the McGill Nursery School present some interesting features both quantitatively and qualitatively. Four percentage scores were obtained for each child for the four months. The average of the four scores was found for every child. In spite of the fact that children over three and a half years old are scored on a scale partly different from the one for children under that age, the scores show fairly steady increase with age. Very little difference was shown between the average scores of the boys and the girls when these were compared. Children who were the only ones in the family scored on the whole somewhat lower on the Social Development Scale than those who had one or more brothers or sisters. Individual differences in score on the Emotional Scale overshadowed the developmental differences even more than they did on the Social Scale.
