Assessment delivery engine for QTIV2 tests

The IMS Question and Test Interoperability (QTI) standard has not had a great takeup in part due to the lack of tools. In the 2006 JISC Capital, three Assessment projects were commissioned: item authoring, item banking, and QTI-compliant test delivery. This paper describes the ‘ASDEL’ test delivery engine, focusing upon its architecture, its relation to the item authoring and item banking services, and the integration of the R2Q2 Web service. The project first developed a java library to implement the system. This will allow other developers and researchers to build their own system or take aspects of QTI they want to implement.
