Since the birth of the intelligence test in the early 20th century, these instruments have gone through tremendous alterations. The revision of such instruments creates an obligation of those who utilize these tests to provide empirical evidence that supports concurrent validity with additional cognitive measures. The purpose of this study is to evaluate the relationship between the Woodcock-Johnson Test of Cognitive Abilities, Third Edition and the Wechsler Adult Intelligence Test, Third Edition. Both instruments were administered to 30 college students attending a Midwest university. The previously collected data was analyzed using a Pearson Product Moment Correlation as well as a t-test, which was used to determine the mean performance for both instruments. The results indicated a high correlation between both the verbal scales and the full scale score of both tests; however, these instruments may yield significantly different scores when administered to the same student.
