These tests develop a clear picture of your students' critical thinking abilities. They can be used to teach critical thinking skills, to predict students' performance on your state proficiency exam, for honors/AP programs, critical thinking courses, college admissions, careers, and employment. Both tests have been used in curriculum and teaching experiments for appraisal of the critical thinking ability of a group and as criteria for program admission and employment.  The Levels X and Z tests can be licensed for use in your own test administration software platform (call 800-458-4849 for details).
