The purpose of the present study was to test the factor structure of the McCarthy Scales of Children's Abilities in preschool children. Seventy‐two boys and 69 girls between 4 and 5 years of age were tested. A factor analysis was carried out by means of the principal components method with varimax rotation. The existence of the Verbal factor and of the Perceptual‐Performance factor was confirmed. The Quantitative and Memory factors appear undifferentiated. As far as the subtests which make up the Motor scale are concerned, they do not constitute a single factor. The significance of these findings is discussed.
