There are various lists and rubrics for evaluating OER available online.
Five common elements of these rubrics include:
- That the content under consideration covers the subject area appropriately
- That the content of the OER is accurate and free of major errors and spelling mistakes
- That the license of the content can be used or altered for the course's needs
- That the OER is clearly written and appropriate for the students' level of understanding
- That the accessibility of the content is appropriate for all students
