# Professionals

**Professionals** are anyone seeking a certification. 

A professional will receive a certification once they have men all the requirements. They can hold more than one certification at any time.

A profesional can be tracked by their wallet address or by an external ID. This allows an off-chain system to manage their information, but still be able to link to their on-chain certifications.
