Before commissioning an applicant as a peace officer or employing an applicant for a police communications operator position, the state Department of Public Safety must require the applicant to submit to the administration of a polygraph examination. The examination may be administered only by a polygraph examiner licensed under the State Occupations Code who is a peace officer commissioned by the department or who has a minimum of 2 years of experience conducting preemployment polygraph examinations for a law enforcement agency. The results must be confidential, but the department and polygraph examiner may disclose the results when there is an admission of criminal conduct. The results of the polygraph examination will be used as a factor in determining the employability of an applicant.
An officer, a peace officer, or a police communications operator already commissioned by the department may not be required to take a polygraph examination.
