CHARACTERISTICS OF THE STANDARD AND SUPPLEMENTAL BATTERIES OF THE WOODCOCK-JOHNSON TESTS OF COGNITIVE ABILITY-REVISED WITH A COLLEGE SAMPLE

The present investigation examined the characteristics of the Woodcock -Johnson Tests of Cognitive Ability-Revised (WJTCA-R) with an independ ent college sample (N = 121). Gender and order effects were examined f or the 14 WJTCA-R subtests that contribute to the Extended Battery. In addition, the relationship between the standard scores obtained on th e Standard and Supplemental Batteries was examined to determine whethe r they represent alternate forms of the WJTCA-R. Significant differenc es existed in subtest performance based on the order in which the Stan dard and Supplemental Batteries were administered. Gender differences also existed on the Visual Matching, Picture Vocabulary and Cross Out subtests, Finally, the coefficient of equivalence for the Standard and Supplemental Batteries approached significance when the administratio n of the Standard Battery followed the Supplemental Battery but fell f ar short of the criterion suggested by Crocker and Algina (1986) when administration of the Standard Battery proceeded the Supplemental Batt ery, the standardized administration.
