The validity of an innovative on-screen assessment

This presentation will describe work done on the new Key Stage 3 ICT (Information &, Communications Technology) test in England. This new test is intended to measure the ICT capabilities of all pupils at the end of the lower secondary phase of education. It is a highly innovative on-screen test, to be delivered, for the first time in 2008, across all secondary schools in England. Specifically, this presentation will describe work done in 2005 to determine whether the test was likely to be valid –, given that 2005 was a pilot year. The presentation will describe how validity has been defined as a multi-faceted, yet unitary, construct, and how multiple sets of data (or varying types and addressing varying purposes) were collected to provide evidence for evaluation of the test’,s validity. The presentation will then go on to describe interpretative approaches taken to arrive at a fair evaluation of the 2005 pilot test’,s validity, and conclude by describing lessons learned, and suggesting how validation and evaluation can be strengthened in future years.
