Numerous legal, criminal, and personal factors can disqualify an individual from obtaining a security guard license or employment. Common automatic disqualifiers include felony convictions, recent violent misdemeanor charges, active domestic violence restraining orders, outstanding legal warrants, or documented histories of fraud, theft, and illegal drug distribution. Additionally, failing a mandatory pre-employment drug screening, lacking a high school diploma or equivalent where legally required, or possessing an uninsurable driving record can disqualify candidates from specific posts.
