When does registration expire?

• A. August 31st of odd years
• B. December 31st of even years
• C. August 31st of even years
• D. January 1st of every year

Answer: (A)

Registration expiration is determined by the state dental board and follows a two-year renewal cycle. For Iowa RDAs, the renewal period ends on August 31 of odd-numbered years. This staggered schedule keeps renewals predictable and spaced apart rather than aligning with the calendar year. So the expiration occurs on August 31 in an odd year, and you’d renew before that date to stay active. The other dates don’t fit the board’s established timing: December 31 of even years would imply even-year expirations, August 31 of even years would shift the cycle to even years, and January 1 of every year would require annual renewals on the start of the year.
