National strategies are needed to mainstream open educational resources (OER) in institutions. While many promising OER initiatives exist, few countries have adequate national strategies. For open universities, adopting a "split-component" course model where some materials are openly licensed as OER while other services have fees could help with sustainability. The Netherlands' €8 million national Wikiwijs program from 2009-2013 aimed to mainstream OER across all education sectors. National strategies are a wise investment that can improve quality through collaborative content development while increasing access and lowering costs through free online materials. Open universities exploring business models where some learning opportunities and services have fees while maintaining OER could fulfill responsibilities for education quality, access, and efficiency.
