Who is responsible for reminding teachers that their license is about to expire?

The correct choice highlights the role of the Department of Education in monitoring and managing educator licensing. The Department of Education is tasked with overseeing the certification and licensure process for teachers, which includes maintaining records and sending notifications regarding license expirations. This ensures that educators remain compliant with state regulations concerning their teaching credentials. Such a function is essential in promoting accountability and maintaining the quality of education by ensuring that all instructors are legally authorized to teach.

Other options do not hold this specific responsibility. Local school districts may have some oversight of their teachers’ credentials, but they typically rely on the state’s Department of Education to manage overall licensure records. The governor does not directly engage in licensing issues related to teachers, as this falls within the purview of educational departments. Similarly, while school principals may be aware of their staff's credentialing status, they are not responsible for official notifications about license expirations.
