To help states, districts, teachers, and other users determine the degree of alignment of Open Educational Resources (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. To allow users to apply these rubrics and evaluate the quality of instructional resources, Achieve partnered with OER Commons to develop an online evaluation tool. OER Commons, an online repository for open education resources, is now hosting the tool and its resulting evaluation data. Every resource available on OER Commons contains an "Evaluate Resource" button that will direct users to the evaluation tool. The coding for the tool is freely available online here. Resources rated on OER Commons will create a pool of metadata, and this metadata will be shared through the Learning Registry with other interested repositories. Download the PDF.
