Personality Test Law and Legal Definition

A personality test is a tool that attempts to measure a person's social interaction skills and patterns of behavior. An employee cannot be legally required to take a personality test, but if they are an employee-at-will, they may be fired for refusing to take such a test. Some employers use personality tests in hiring in an attempt to reduce employee turnover.

Personality tests can contain biases against members of a minority class, though if this is the case, and it can be proven, the test would then be against the law. If a personality test asks questions meant to elicit religious beliefs, sexual practices, or race norms, the test is illegal, and a legal claim may be made against an employer over a test that is deemed to be psychologically invasive, though such lawsuits are very expensive and difficult to win.
