The purpose of this study was to relieve test anxiety in high school juniors preparing to take the ACT: a high-stakes, college admissions, standardized test. Participants included 81 eleventh grade students (25 males, 56 females) from a Midwestern public high school. Results demonstrated that relaxation training in the experimental group significantly lowered student’s perceptions of test anxiety from pre-test to post-test. Further research regarding systematic deep breathing and relaxation techniques is needed
