Personality Assessments have been available for about 60 years. Some of them have obtained a great deal of validation research. However, it is important to understand that they are not actually job behaviour assessments and such validation is not relevant to job performance. In most cases, the validation simply means that the assessment favorably compares with other means of assessing personality.
Many people are fooled into thinking that this large amount of research indicates that they are valid and useful tools for job assessment. In fact, many of those assessments specifically state that the instrument does not predict job performance.
It makes no sense to use an assessment for job selection that was never designed for the workplace and has no ability to predict job performance. Some people say that they can effectively use personality assessments for employee development. However, this also makes no sense. The main point of employee development is to improve performance and if an assessment does not measure the factors that relate to job performance, how can it significantly help to develop employees?
