Three short forms of the McCarthy Scales of Children's Abilities (MSCA) have been developed to screen the cognitive skills of young children suspected of learning disorders and developmental delays. Based on a sample of 40 children between the ages 5–13 to 6–13, correlations of .92, .61, and .72 were obtained between the scores of the children on the full form of the MSCA and the Kaufman, Taylor, and MST short forms, respectively. The Kaufman short form also had the highest test-retest reliability at r = .87. The advantages of the Kaufman short form over the other two short forms are discussed.
