The Role of Polygraph in Pre-Employment Background Checks
Hiring the right candidate is about more than resumes and references—it’s about honesty, integrity, and trust. For positions involving security, law enforcement, or high liability, a pre-employment polygraph exam can be a critical part of your background screening process.
At Spectrum Polygraph Services, we provide professional, confidential, and legally sound polygraph exams for hiring agencies, police departments, private companies, and security firms across Southern California.
Why Employers Use Pre-Employment Polygraph Testing
Polygraph testing helps employers:
- Verify truthfulness about prior criminal activity or substance use
- Validate employment history and qualifications
- Protect sensitive assets and information
- Avoid negligent hiring lawsuits
While polygraph use is restricted for general employment under the Employee Polygraph Protection Act (EPPA), there are important exceptions.
Who Can Legally Use Polygraph Tests for Hiring?
Pre-employment polygraph testing is permitted for:
- Law enforcement agencies (police departments, sheriff’s offices, corrections)
- Government agencies with security clearance roles
- Private security companies
- Businesses handling controlled substances (e.g., armored transport, pharmacies)
What Topics Are Covered During the Test?
Depending on the role, topics may include:
- Prior criminal offenses
- Drug or alcohol use
- Undisclosed terminations or dishonesty
- Theft or misuse of company property
- Fraud or financial misconduct
All questions are discussed in advance with the applicant and fully documented in the report.
