What are the legal requirements to become a security guard in Arizona?

To become a security guard in Arizona, individuals must meet specific legal requirements established by the state. Being at least 18 years old is a fundamental criterion, as this age requirement ensures that candidates have reached a level of maturity and responsibility suitable for the role. Additionally, passing a background check is essential; this process evaluates an applicant's criminal history to ensure that individuals in this position can be trusted to uphold safety and security standards and are not disqualified due to past infractions.

The other options do not align with the legal requirements for security guards in Arizona. A college degree is not mandatory, there is no stipulation of U.S. citizenship as a requirement, and prior experience in law enforcement is also not a prerequisite for all security guard positions. Thus, the answer accurately reflects the necessary qualifications.
