This paper examines the sustainability literacy of one pilot group of Science, Technology, Engineering, and Maths (STEM) students in one U.S. HE institution. Currently, the absence of understanding how sustainability goals and challenges are related is missing from many HE programs. Students took the sustainability literacy test (SULITEST) and showed mixed results in regards to their sustainability literacy. These initial results indicate that sustainability tenets are well ingrained by the students, but not the application of sustainability to their lives. The results presented here provide a first indication of the gaps in sustainability education for STEM students in higher education.
