Psychometric tests collect data about various aspects of personality. This information is expressed numerically and the quantitative data is then analyzed using statistical techniques. Therefore, the results obtained present an objective viewpoint without the interference of any personal bias of the evaluator.
From recruitment to long-term career development, these tests provide a great deal of reliable information to make important personnel decisions. If you use the tests, ensure that they are appropriate for you needs, and that they've been rigorously evaluated.
