Training , Other Qualifications, and Advancement Most States require that guards be licensed. To be licensed as a guard, individuals generally must be 18 years old, have no convictions for perjury or acts of violence, pass a background examination, and complete classroom training in such subjects as property rights, emergency procedures, and seizure of suspected criminals. Most employers prefer guards who are high school graduates. Some jobs require a driver's license. Employers also seek people who have had experience in the military police or in State and local police departments.
Most persons entering guard jobs have prior work experience, although it is usually unrelated.
Because of limited formal training requirements and flexible hours, this occupation attracts some persons seeking a second job. They should be mentally alert, emotionally stable, and physically fit in order to cope with emergencies. Guards who have frequent contact with the public should be friendly and personable. Some employers require applicants to take a polygraph examination or a written test of honesty, attitudes, and other personal qualities. Many employers require applicants and experienced workers to submit to drug screening tests as a condition of employment.
