A Delivery Engine for QTI Assessments

The IMS Question and Test Interoperability (QTI) standard has had a restricted take-up, in part due to the lack of tools. This paper describes the `ASDEL' test delivery engine, focusing upon its architecture, its relation to item authoring and item banking services, and the integration of the R2Q2 web service. The tools developed operate with a web client, as a plug-in to Moodle, or as a desktop application. The paper also reports on the load testing of the internal services and concludes that these are best represented as components. The project first developed a Java library to implement the system. This will allow other developers and researchers to build their own system or incorporate aspects of QTI they want to implement.
