Open Educational Resources (OER) offer opportunities for increasing equity and access to high-quality K–12 education. Many state education agencies now have offices devoted to identifying and using OERs and other digital resources in their states. To help states, districts, teachers, and other users determine the degree of alignment of OERs to the Common Core State Standards, and to determine aspects of quality of OERs, Achieve has developed eight rubrics in collaboration with leaders from the OER community.
