QTI (Question and Test Interoperability) is a specification from IMS Global Learning Consortium for a file format for questions, tests, and reporting results. Version 2.1 was published in 2006 as a major revision from earlier versions to improve the item content model, add support for assessments, and improve implementation. Key changes included alignment with other IMS specifications, adding support for XHTML, math, and adaptive items to the item model, and adding features like pre-conditions and branching to the assessment level. The specification aims to support validation of items and assessments as well as external response processing.
