Which of the following roles does NOT require obtaining an appropriate endorsement according to the Texas Private Security Act?

According to the Texas Private Security Act, specific roles in the security industry require individuals to obtain an appropriate endorsement to ensure they meet the necessary standards and qualifications for their positions. The functioning of alarm systems monitoring, locksmithing, and private investigation falls within the categories that necessitate a licensed endorsement because they directly involve security services that can significantly impact the safety and security of individuals and property.

In contrast, a personal trainer does not engage in activities that require such regulatory oversight under the Texas Private Security Act. While personal trainers do play a crucial role in the well-being of individuals through physical fitness and health, their work does not implicate security measures or services that the act is designed to regulate. As a result, they are not required to obtain an endorsement, distinguishing this role from those that do require it.
