The Learning Object Review Instrument (LORI) was developed to evaluate learning objects based on 9 criteria: content quality, learning goal alignment, feedback and adaptation, motivation, presentation design, interaction usability, accessibility, reusability, and standards compliance. Each criterion is rated on a scale of 1 to 5, with options to select "not applicable" or provide comments. LORI was created for the E-Learning Research and Assessment Network and the Portal for Online Objects in Learning, with support from various organizations, to provide a common review format for selecting high quality learning objects from repositories.
