Which entity must register an applicant who meets training and application requirements?

The correct choice is the director of public safety, as this entity is responsible for overseeing the registration process for applicants who meet the training and application requirements for private security. In Ohio, the director of public safety has the authority to manage and implement rules related to the licensure and registration of security professionals, ensuring compliance with state regulations. This oversight is crucial for maintaining the integrity and professionalism of security services in the state.

Municipal corporations often have their own regulations and policies, but they do not handle the statewide registering process for security applicants. The Ohio peace officer training commission focuses on training for peace officers, not directly on the registration of private security applicants. Local police departments may engage in hiring or may oversee local enforcement of security practices, but they typically do not manage the registration of individuals across the state. The role of the director of public safety is specifically designated for this purpose, making that the accurate answer to the question.
