All Seminars Prior Approved For Class A CE Credits All programs are submitted to the AANA for prior approval of Class A credits (assessed CE’s) and meet the new CPC requirements. Based on the new CPC requirements, each CRNA is required to obtain 60 Class A credits for each 4-year CPC cycle. These credits can be earned at any point during the 4-year cycle. Each CRNA also needs 40 Class B credits which do not require prior approval and are non-assessed. If more than 60 Class A credits are earned in a given 4-year cycle, those excess credits can be applied to the Class B requirement. Thus, all 100 credits needed in the 4-year cycle can be fulfilled with Class A CE credits.
