What is the minimum age requirement to apply for a private investigator license?

In Tennessee, the minimum age requirement to apply for a private investigator license is 21 years old. This age limit is established to ensure that applicants have reached a level of maturity and life experience that is deemed necessary for the responsibilities associated with investigative work. At 21, individuals are generally viewed as having better judgment and the ability to handle potentially complex and sensitive situations.

The other age options listed are not aligned with the state's regulations, which specifically stipulate that applicants must be at least 21 years of age to qualify for a private investigator license. This requirement reflects a standard practice across many states, which aim to maintain a certain threshold of age and experience in the private investigation industry.
