The present study is intended to examine whether the Wechsler Adult Intelligence Scale III or Woodcock-Johnson III Cognitive Abilities would better predict reading achievement on the WJ III Achievement in the college student population. Participants included 29 college students attending a university in the Midwest, being evaluated for a learning disability or academic accommodations. Data were analyzed using Pearson r correlation, Fisher z, and t-test for each intelligence test in comparison to achievement subtests. Results from this study indicated that both IQ scores obtained from the WAISIII and the WJ-III COG correlated with reading significantly, but not highly enough to be construed as achievement tests due to only moderate correlations. Considering the results of this study an examiner may choose either instrument to use when assessing intelligence. Limitations to this study are presented.
