Every two years by the last day of your birth month.
For example, if your birthday is June 20, your typical licensing period runs from July 1 of either an even or an odd year to June 30 of the next even or odd year. This means that only education taken between July 1 through June 30 of the next year will count toward your renewal. If you renew your license early, you must wait to take any education for your next licensing period until the new licensing period begins.
