Open Educational Resources (OER) remove barriers to access instructional material. In light of their increased availability and use, a body of research has emerged to examine the impact of OER on college student success. While many of these studies have broadly examined efficacy across a variety of disciplines, the current study specifically examined the impact of the type of textbook (commercial vs. OER) on course content mastery within an undergraduate sample of introductory psychology students (N = 63) while controlling for instructor and student differences. Results indicated that there were no significant differences in content mastery between those students in introductory psychology courses who were assigned a traditional commercial textbook and those who were assigned an OER textbook. These results support that OER can be equally effective as traditional, commercial textbooks and have implications for course material selections that help ensure access for all students.
