While there can be dramatic benefits gained from using testing in the employee selection process, there are potential issues companies need to understand prior to implementing any tests. The first issue is validity; whether or not the test measures the specific criterion it is supposed to measure and can predict future job performance or success. An employer should be able to demonstrate that those who do well on the test do well in performing the job and those who score poorly on the test perform poorly on the job. For example, if an employer can demonstrate that a typing test and skills tests using Microsoft Office software products constitute a fair sample of the content of an administrative assistant job, then the tests will probably be considered content valid.
