Why does EAA re-use some questions from previous years papers and why do the same questions appear in various papers?
A At the School and State level we draw comparisons between each year level to see how different cohorts progress over time. In order to do this we need to know how much more difficult one test paper is over another. By comparing the information obtained from a few questions that appear in two different papers we can get a good indication of the relative difficulty of each paper. This process is called ‘equating’ and is applied to test papers across year levels (called Vertical Equating) and also across calendar years (Horizontal Equating).
