The IMS Question and Test Interoperability specification, version 2.1 (QTIv2.1) became a final standard in summer 2012. Our Consultant, Sue Milne, is an active member of the QTIv2.1 Profiling Working Group, which is composed of experienced practitioners who are implementing QTIv2.1, creating questions and tests conforming to the QTIv2.1 specification, and preparing the way to new versions of the specification. Participants are building profiles of QTIv2.1 elements and attributes to facilitate conformance testing and encourage developers to obtain conformance certification
