Which of the following is NOT an acceptable form of registration documentation for Dental Assistants?

The correct choice highlights that photocopies of the registration are not considered acceptable forms of documentation for Dental Assistants. In most professional settings, especially in healthcare, original documents are required to verify credentials and to ensure authenticity. Original registration certificates serve as official proof of standing and are typically used for validation during audits or inspections.

While duplicate registrations issued by the Board, original registration certificates, and certification documents from training are recognized forms of documentation that can confirm a Dental Assistant's qualifications and compliance with state regulations, photocopies do not provide the same level of assurance. They can be easily altered or fraudulently reproduced, which is why they are often deemed insufficient for official use. This emphasizes the importance of maintaining integrity and security in professional documentation.
