Developing trust between a student and instructor in undergraduate classrooms has been shown to provide numerous educational outcomes such as retention in the field, commitment to the material and teaching practices, and improved final grade outcomes. This study seeks to examine what traits and practices of a professor can foster trust between a student and instructor in an undergraduate class. Virtual interviews were conducted with students from the University of Connecticut, Southern Connecticut State University, and Yale University asking students to recall their favorite professors and to describe their traits or practices.
