In April 2021, MHEC convened a working group of institutional, state and national leaders to help advise its efforts to develop a set of principles to improve consistency and reliability in the field for measuring cost savings and the return on investment of OER. This group will advise MHEC throughout this process. The first meeting focused on defining what we hope to accomplish, why this work is important, whom it is designed for and how we should develop the principles. The group collectively acknowledged that this is a big challenge with multiple dimensions, but also a worthwhile endeavor. Below are key themes and takeaways from the first meeting that will guide and define the scope of this work.
