Assessing professional skills, such as teamwork, global awareness, ethics and creative problem solving, in the Science, Technology, Engineering and Mathematics (STEM) disciplines encourages growth and experience for students. The paper focuses on the professional skill, global awareness, and gauging students' knowledge about this skill. According to the Model of Domain Learning (MDL), as students progress throughout their education in a domain, the knowledge of the domain becomes more cohesive and deeper. To assess students' knowledge of global awareness, we developed an instrument, i.e., a questionnaire, which gauges what students know about the world and specific nations based upon the following categories: customs and culture, religion, geography, economy, food, languages, history, health, politics and the environment. The plan for the administration of the questionnaire is discussed. Primary findings will also be used to group the questionnaire items into three developmental stages of the MDL-acclimation, competency, and proficiency.
