IMS Global Learning Consortium develops and maintains, among other specifications, the Question & Test InteroperabilityⓇ(QTIⓇ) standard, to enable the exchange of item, test, and results data between authoring tools, item banks, test constructional tools, learning systems, and assessment delivery systems.
A lot of products and vendors claim QTI compliance, and even use the QTI name, but that can be misleading. Here’s the fine print: being QTI-compliant isn’t the same thing as being IMS-certified. The requirements for the latter are much more stringent.
With QTI compliance, a product’s implementation and interpretation of the QTI standard are often untested. If you assume interoperability because of the mention of QTI, you might be disappointed. Subsequently, when untested implementations of QTI-compliant products fail, it gives “interoperability” and standards like QTI a bad name.
In 2014, TAO became the first product to obtain IMS conformance certification for QTI in all four categories: Authoring and Editing systems, Delivery systems, Item and Test bank systems, and most importantly, the QTI content itself. Taken together, they make test content completely portable, which is of critical importance as users migrate from legacy proprietary platforms to open, interoperable environments. Additionally, QTI can be used to create best-of-breed solutions; combining delivery and authoring modules from multiple vendors; where adherence is key in building these learning solutions of the future.
