Which statement best describes lie detector test requirements in employment?

• A. Contractors may require lie detector tests for all applicants
• B. Public agencies may require lie detector tests for their employees
• C. Both private employers and public agencies may require lie detector tests
• D. No one may ever require lie detector tests

Answer: (B)

The key idea is how lie detector tests are regulated: private employers are largely barred from requiring polygraphs for applicants or employees, while government (public) agencies can use them in certain security- or sensitive-duty positions. That’s why public agencies may require lie detector tests for their employees, whereas private companies cannot rely on such testing in typical hiring or ongoing employment. This distinction reflects the balance between privacy protections in the private sector and security considerations in government roles.
