Which of the following information must a licensee report to the Board?

A licensee must report their name and license number to the Board because this information is essential for the Board to maintain accurate records and ensure that practitioners are properly licensed to practice in the state. The name and license number uniquely identify the individual, confirming their credentials and allowing the Board to monitor compliance with state regulations.

Maintaining up-to-date records is critical for regulatory oversight, which includes verifying a veterinary technician's qualifications and handling any issues that may arise concerning their practice or conduct. This ensures the safety and well-being of animal patients and the integrity of the veterinary profession.

While emergency contact numbers, previous employment history, and medical records may be relevant in certain contexts, they are not mandatory reports to the Board like the name and license number are. Hence, it is paramount that the Board has accurate and current information on each licensee's identity and licensing status.
