The Wonderlic Contemporary Cognitive Ability Test (formerly Wonderlic Personnel Test) is an assessment used to measure the cognitive ability and problem-solving aptitude of prospective employees for a range of occupations. It is a proprietary assessment created and distributed by Wonderlic. It consists of 50 multiple choice questions to be answered in 12 minutes. The test was created in 1939 by Eldon F. Wonderlic (1909–1980), while he was a graduate student at Northwestern University. The score is calculated as the number of correct answers given in the allotted time. A score of 20 is intended to indicate average intelligence.
