The Driving OER Sustainability for Student Success (DOERS) Collaborative is a group of higher education systems and statewide/provincewide initiatives that are committed to supporting student success by promoting free, customizable open educational resources (OER). Launched in 2018, DOERS helps member organizations implement, scale, and sustain OER by advancing research and policy, sharing tools and learnings, and showing how OER can foster student success. With 41 participating systems and statewide/provincewide initiatives, we serve over 9.3 million students at over 1,000 colleges and universities in the US and Canada.
