In this study, a scale development study was carried out to measure the academic achievement in the undergraduate physics course “Conservation of Mechanical Energy in Conservative Systems.” The developed test consists of seven openended questions, and these questions correspond the first five steps of the revised Bloom taxonomy steps. Since the test consisted of open-ended questions, an answer key was also prepared. The validity and reliability studies of the test were carried out with a total of 317 pre-service Science teachers who took the Physics 1 course. As a result of these studies, the test was found to be valid and reliable according to Cronbach’s alpha value of .758, item discrimination average of .364, and item difficulty average of .264, as well as expert opinions. It can be said that the test developed in the light of all this information obtained is a valid and reliable academic achievement test for solving problems on the Conservation of Mechanical Energy in Energy Conservation Systems in Physics 1 Course, and it can be suggested for use by researchers/ practitioners.
