Licensees performing a service that is not specified in the rules, requires a:

• A. Written authorization
• B. Permits
• C. Temporary permit
• D. Certificate of training

Answer: (D)

When a service isn’t listed in the rules, the licensee must have documented training in that service. A certificate of training provides that documentation, showing the practitioner completed an approved program and has the knowledge and skills to perform the procedure safely and competently. This protects clients and keeps practice aligned with professional standards, covering technique, sanitation, contraindications, and product use.

Written authorization isn’t the standard mechanism for adding a service, and permits or temporary permits relate to facilities, events, or regulatory durations rather than proving individual competence. The certificate of training directly demonstrates the required competency to perform the unlisted service.
