This 33-question research-based multiple-choice test is designed to evaluate students� conceptual understanding of energy in algebra- or calculus-based introductory physics courses. The survey is based on investigations of students� difficulties in energy and should be given in a 30-minute period. Statistical results have shown the survey to be reliable and valid. Details on the construction and analysis of the survey are available in L. Ding, <em>Designing an Energy Assessment to Evaluate Student Understanding of Energy Topics</em>, Ph.D. Dissertation, North Carolina State University, 2007, and L. Ding, R. Chabay, and B. Sherwood "How do students in an innovative principle-based mechanics course understand energy concepts?" <em>Journal of Research in Science Teaching</em> 2013, <b>50</b>, (6), 722�747. This assessment is free for use by instructors in their classroom. However, as it takes years of development effort to create and validate reliable assessment instruments, the file is password-protected. Furthermore, the author requests that 1. students are not given copies following examination; and 2. none of the questions are incorporated into web-based question delivery systems without adequate security to prevent printing or unauthorized access by students.
