For how many years must licensees maintain proof of continuing education?

In Iowa, dental hygienists are required to maintain documentation of their continuing education for a period of four years. This timeframe aligns with the state's licensure renewal cycle, which mandates that licensees complete a certain number of continuing education hours to ensure they stay current with the latest practices and information in the field of dental hygiene. Keeping proof for four years allows for verification of compliance during the renewal process and promotes accountability among practitioners. This requirement helps to reinforce the importance of ongoing education in upholding professional standards and enhancing patient care.
