A four-factor model of list score is broadly upheld (i.e., Verbal Comprehension, Perceptual Organization, Freedom from Distractibility, and Processing Speed) (Canivez, Neitzel, and Martin, 2005). The WISC-III has high interior consistency for each of the three IQ scores and the four elements, going from .80 to .97 (Canivez, Neitzel, and Martin, 2005; Kaplan and Saccuzzo, 2001). This mirrors the 11 subtests (Symbol Search and Coding rejected) detailed moderate to incredible inward textures, of .61 to .92 (Kaplan and Saccuzzo, 2001).
