Scores on Kaufman's (1977) McCarthy short form and the McCarthy Screening Test (1978) were obtained for a sample of 53 first graders in their first month of school. Nine months later, the Metropolitan Achievement Test was administered to the sample. The correlation between Kaufman's estimated General Cognitive Index and the Metropolitan Basic Battery raw score was .71. Biserial correlations between “At Risk” and “Not At Risk” classifications of the McCarthy Screening Test and Metropolitan Basic Battery raw scores ranged from .43 to .78. Kaufman's short form scores usually indicated a smaller number of false negatives than did McCarthy Screening Test scores. Implications of these findings for these findings for first‐grade screening are discussed.
