(topic learningBase+learningInteractionBase-d) (topic learningBase+learningInteractionBase-d learningAssessment) A Learning Assessment presents questions or interactions that measure progress, encourage recollection, and stimulate reinforcement of the learning content, and can be presented before the content as a pre-assessment or as a post-assessment test. The interactions use a sub-set of the Question-Test Interoperability (QTI) specification, implemented as a DITA domain specialization. The <learningAssessmentbody> element is the main body-level element in a learningAssessment topic.
