Which of the following is required for issuing a letter of authority?

The requirement for issuing a letter of authority is board approval. A letter of authority is a formal document that grants a licensee the ability to operate in certain capacities within the private security sector. This document is essential for ensuring that individuals or businesses are authorized to perform specific duties according to Texas law.

Board approval is critical because it ensures that the agency or board reviews the qualifications and compliance of the applicant with all necessary regulations and standards set by the Texas Department of Public Safety. This process helps to uphold the integrity of the private security industry and protects the public by ensuring that only qualified individuals are permitted to provide security services.

In contrast, while being currently licensed, proof of insurance, and completion of training are important elements in maintaining a security business, they do not specifically pertain to the issuance of a letter of authority. These may be prerequisites or necessary conditions for operating a security business, but they do not replace the need for formal approval from the board which validates the authority to operate.
