The OpenER project at the Open University of the Netherlands aimed to increase access to higher education through open educational resources. It exceeded targets with over 550,000 unique website visits and 4,400 registered learners. Evaluation found most visitors and learners were satisfied and many planned to pursue further study. Lessons learned included needing top management support and identifying champions. The university will likely continue the OpenER approach, and is considering making all its materials open resources or launching a new initiative, depending on funding and policy changes.
