A method is discussed for securing Factorial Verbal and Factorial Performance IQs from the WISC‐R by means of an orthogonal rotation of the axes that describe the plane of the first two principal components derived from an analysis of the intercorrelations of the WISC‐R subtests. The reliability and validity of these IQs also are described. Sex differences in normal children are found, as well as differences between normal and learning‐disabled children.
