RETA Authorized Instructors (RAIs)

The RETA Authorized Instructor (RAI) Program is designed to assure that candidates have access to high-quality training as they prepare to qualify for CARO, CIRO and CRES credentials.   RAIs must meet rigorous RETA standards, both for their knowledge of refrigeration systems and their skill as trainers.  

RETA conducts confidential surveys of an RAI's trainees when an RAI applies for recertification every three years.  While all candidates must earn their RETA credentials with their performance on RETA examinations and in meeting other certification requirements, the RAI credential assures candidates that they have access to instruction that has met rigorous RETA standards.  

If you have questions, or would like to request an application, please contact Dan Reisinger at RETA HQ (541) 497-2955 or visit the RAI Certification page.
