Nowadays, more and more assessment instruments are taken online, at home, by candidates (unproctored assessment). Unproctored assessment has many advantages, such as lower costs and more user-friendliness. One of the crucial questions with online- or web-based assessment concerns fraud. Is it easier for candidates to commit fraud on an online assessment? And if so, what is the effect of fraud on an online test? These questions are important for the future use of web-based instruments and personnel selection in general.

We examined if online testing leads to higher risks of fraud, and if so, to what extent. Respondents (N = 431) were allocated to two different groups: an 'honest' group (n = 253) which received no particular instructions prior to the test and a 'fraud' group (n = 178) of which the respondents were instructed to commit fraud as effective as possible. All respondents completed an online intelligence test, derived from the Q1000 intelligence test of Meurs HRM advisors. Results show an effect size of .40 for the overall score on the test. Effect sizes for the subtests varied from .09 for Syllogisms to .39 for Vocabulary. The authors conclude that fraud pays off. The more fraud strategies respondents use, the higher they score on the online intelligence test.
