On-Demand Testing and Maintaining Standards for General Qualifications in the UK Using Item Response Theory: Possibilities and Challenges
He, Qingping
Educational Research, v54 n1 p89-112 2012
Background: Although on-demand testing is being increasingly used in many areas of assessment, it has not been adopted in high stakes examinations like the General Certificate of Secondary Education (GCSE) and General Certificate of Education Advanced level (GCE A level) offered by awarding organisations (AOs) in the UK. One of the major issues with on-demand testing is that some of the methods used for maintaining the comparability of standards over time in conventional testing are no longer available and the development of new methods is required. Purpose: This paper proposes an item response theory (IRT) framework for implementing on-demand testing and maintaining the comparability of standards over time for general qualifications, including GCSEs and GCE A levels, in the UK and discusses procedures for its practical implementation. Sources of evidence: Sources of evidence include literature from the fields of on-demand testing, the design of computer-based assessment, the development of IRT, and the application of IRT in educational measurement. Main argument: On-demand testing presents many advantages over conventional testing. In view of the nature of general qualifications, including the use of multiple components and multiple question types, the advances made in item response modelling over the past 30 years, and the availability of complex IRT analysis software systems, coupled with increasing IRT expertise in awarding organisations, IRT models could be used to implement on-demand testing in high stakes examinations in the UK. The proposed framework represents a coherent and complete approach to maintaining standards in on-demand testing. The procedures for implementing the framework discussed in the paper could be adapted by people to suit their own needs and circumstances. Conclusions: The use of IRT to implement on-demand testing could prove to be one of the viable approaches to maintaining standards over time or between test sessions for UK general qualifications.
