Validity of personality tests

Well-designed and thoroughly tested personality assessments afford an extra element of information in the decision-making process that other forms of assessment are unable to offer. Specifically, when used in conjunction with a formal job-analysis, personality assessments become legally-defensible methods of selection in countries where unsuccessful candidates are able to appeal such decisions. Not all personality assessments are the same of course and the degree of validity afforded by an instrument will vary. Before investing in tests, it is important to understand the purpose for which the test was designed and in which different populations it has been tested. There are a huge number of free personality tests available on the internet and whilst these may be fun to complete, they usually are unsuitable in work situations because a ‘free test’ developer cannot, by implication, afford to invest in initial and ongoing studies of the reliability and validity of the test under different conditions and within different populations.
