On the design and development of an assessment system with adaptive capabilities

Individual assessment is an important tool in this society. Tests can be created according to the Classical Test Theory (CTT) or to the Item Response Theory (IRT), the latter giving the possibility to build Computerized Adaptive Testing (CAT) systems. In such a context, the paper introduces the available systems for CTT, IRT and CAT, highlights the main characteristics that are taken as initial requirements for the design of a novel system, called UTS (UnivAQ Test Suite), whose architecture and initial functionalities are presented in the paper.
