How frequently must researchers renew their CITI training?

The correct answer is that researchers must renew their CITI training every three years. This renewal timeline ensures that researchers stay updated with the latest ethical standards, regulations, and best practices in research involving human subjects, animal welfare, and other related areas. This periodic renewal is critical for maintaining compliance with institutional policies and federal regulations, which are continuously evolving to reflect new knowledge and societal concerns.

By requiring a renewal every three years, the CITI program balances the need for ongoing education with the practicalities of researchers' obligations. This timeframe is generally seen as a good practice in many educational and professional development sectors, ensuring that individuals remain knowledgeable without overwhelming them with the need for constant retraining.
