Open educational resources are and always will be free, but not all free resources are OER. With free resources, educators can use the materials but do not necessarily have the right to modify or share them with others. In order to be considered OER, a resource must have the “5R” permissions. The 5R’s include:
Retain: Freely making and owning copies of resources in any format for any amount of time.
Reuse: Freely using the materials in any way.
Revise: Edit, adapt, and modify the materials to any use.
Remix: Combine one or more or parts of resources into one resource.
Redistribute: Share and distribute resources in any format.
