There are a number of standard tests available and most organizations do not have an interest in developing their own. Personality tests look at the habitual ways that people act. Interest tests measure work interests.
Specialized tests measure specific skills.
Among the companies interviewed, those that offer testing primarily administer cognitive and specific skills testing to their non-exempt populations. Often the personality and interest results are utilized for succession and career planning. The American Psychological Association has standards for test development and use. Industrial test developers are available to assist an organization in the design and development of tests or the selection and validation of appropriate standardized tests. Among the Corporate Test Administrators I interviewed, many warned that cognitive testing can present challenges in the area of adverse impact.
