What does the Wonderlic Personnel Test measure?

The present investigation examined the concurrent validity of the Wonderlic Personnel Test and Woodcock-Johnson-Revised Tests of Cognitive Ability which were administered to 37 college students, 27 women and 10 men, who ranged in age from 18 to 54 years (M=27.1, SD=8.7). Analysis yielded significant correlation coefficients between the Wonderlic Total score and the score for the WJ-R Broad Cognitive Ability Standard Battery (r = .55) and the Comprehensive Knowledge score (r= .34). Performance on the Wonderlic was not significantly correlated with fluid reasoning skills (r=.26) but was most strongly associated with overall intellectual functioning, as measured by the Woodcock-Johnson Standard Battery IQ score. While scores on the Wonderlic were more strongly associated with crystallized than fluid reasoning abilities, the Wonderlic test scores did not clearly show convergent and divergent validity evidence across these two broad domains of cognitive ability.
