With IMS Question and Test Interoperability v2.1 almost ready for final release, this draft briefing paper provides an introduction to the specification based on the most recent public draft available.  It covers the structure and purpose of the specification, and looks at the history and background to it as well as reasons for its adoption and some common concerns and criticisms.  A final version will be released with the final version of the specification; in the meantime, we hope this paper will provide a useful guide to this significantly improved specification.  It is likely to be of particular interest to IT managers, learning technologists and developers interested in online and electronic assessment and new to QTI.
