ACS Exams has produced nationally standardized exams for over 70 years. For some courses, such as high school chemistry and general chemistry, the Exams Institute produces two forms of the test to assist instructors in minimizing opportunities for cheating. Because there are two forms of the same exam, we are able to determine the nature of item order on student performance on the exam. This poster will report the results for our analysis for the high school exams from the past decade.
