Are private investigators allowed to conduct lie detector tests in Texas?

In Texas, private investigators are not authorized to administer polygraph tests, or lie detector tests. The law stipulates that the administration of polygraphs is a specialized profession that requires specific qualifications and licensing separate from that of a private investigator. This generally includes certified examiners who have undergone rigorous training and certification processes governed by state regulations.

While some professions and specific roles may involve the use of polygraphs, private investigators do not fall into that category under Texas law. This means that without the appropriate certification and legal authorization, private investigators would be prohibited from conducting such tests. Understanding the legal scope of practice for private investigators in Texas is essential for compliance and to avoid any potential legal issues.
