Cognitive Tests

  1. Watson-Glaser Critical Thinking Appraisal This test has legions of fans, including JCPenney, Coors, and government intelligence agencies. It measures problem-solving skills, creativity, and other factors with 40 rather difficult questions. It should not be used for entry-level positions but is great for management and higher. For sample questions, see "Let's Turn the Tables".
