If you have heard of the underlying principles of computer-adaptive testing (CAT), you will know the concept is relatively straightforward (avoiding the obvious discussion of the complex algorithms underlying this concept). That however does not necessarily mean it is appropriate for you or your organisation. CAT is a form of computer-based testing which can identify at which level a person is performing, i.e. what their 'ability level' is. This is achieved through tailoring

EPEC's Founder and Exec Director, Professor John Barnard delivered his presidential address at the IACAT Conference on 14 September 2015 in Cambridge, England. Entitled, 'Improving Precision of CAT Measures', Prof Barnard questioned dichotomous scoring (scoring only as either correct or incorrect). He suggested that a test taker may not always have 100% confidence in an answer when they have selected the correct option, and likewise, may have some knowledge of the concept bei

As Computer Adaptive Testing (CAT) is being adopted, the controversial discussion relating to whether candidates should be allowed to review and change their responses under exam conditions has increased. In comparable paper-and-pencil testing conditions, it has been argued that candidates would be able to alter previously selected answers at their leisure (time-permitting of course), and as such, this should also be accommodated for in CAT conditions, to ensure candidates ar
