ABSTRACT
The security of online testing is often one of the main criticisms that is levelled at psychometricians. In the psychometrics industry, the author's speak of.70 being the benchmark of reliability for two parallel forms of an ability test. The British newspaper The Telegraph once featured a cartoon on the subject of online testing. Given the established and recognised effectiveness of ability tests compared to other selection methods, failure to carry out supervised retesting in an attempt to cut costs in the selection process may turn out to be a false economy. Ability tests are among the most valid ways of reducing candidate numbers, so are often particularly useful as initial screening tools in an assessment process. In terms of cheating on unsupervised assessments, there are various sophisticated statistical methods and ways to randomise content so that different candidates see different versions of an assessment. There are certainly things people can do to counteract cheating on workplace assessments.
