To maintain their real estate licenses in the state(s) where they operate, agents and brokers need to participate in defined amounts of continuing education (CE) each year or recurring time period. These requirements are set forth in state laws and are administered by state real estate commissions. The specific requirements, time frames, and due dates vary considerably across states—as do the requirements for obtaining a license, called pre-licensing, and supplemental one-time novice training, called post-licensing.
