Final answer:
The statement is true; sponsoring brokers are notified by registered or certified mail to their last known business address when their associate broker or salesperson is involved in a hearing.
Step-by-step explanation:
True. In the context of regulatory compliance for real estate professionals, the statement regarding notification is accurate. If a hearing involves an associate broker or salesperson, the licensing regulations typically require that the sponsoring broker is also notified. This notification is often mandated to be sent via registered or certified mail to the broker's last known business address.
The purpose of this is to ensure that the sponsoring broker is aware of any proceedings that may impact their associate, and can take any necessary actions or provide support as appropriate.
