“The study indicates that, based on two years of implementation across scores of colleges, OER can be an important tool in helping more students—and particularly low-income and underrepresented students---afford college, engage actively in their learning, persist in their studies, and ultimately complete,” said Dr. Karen A Stout, president of the national community college reform network Achieving the Dream (ATD), which released the study. “Data show that even using the most conservative estimates, cost savings are significant and that OER content plays a role in helping strengthen instruction and learning across not just a few courses but entire degree pathways.”
