The purpose of this study was to determine if there is a relationship between: 1) comprehensiveness of student developed model tests and final exam score, 2) the quality of student developed model tests and answer keys combined, and final exam score, and 3) student developed model test similarity to instructor final exam and final exam score. Students in a freshman fluid power class, in Manufacturing Engineering Technology, were given a homework assignment to create a final exam, and the corresponding answer key, over the material that they would be examined over on the final exam given by the professor. Student constructed exams and answer keys were handed in before the actual final exam. Two professors used rubrics to independently evaluate student tests and answer keys, and compare them to the instructor's final exam. Results were correlated with student performance on the final exam. Support was found for the first two hypotheses.
