The Refrigerating Engineers and Technicians Association (RETA)The Refrigerating Engineers and Technicians Association (RETA) is the most recognized organization in the country dedicated to the professional development of industrial refrigeration operators and technicians. Founded in 1910, RETA is a non-profit membership and certification organization currently based in Albany, Oregon.
What is RETA?
The Refrigerating Engineers & Technicians Association (RETA), founded in 1910, is an international society of individuals and companies involved in the design, operation and service of industrial refrigeration systems. Its purpose is to provide education and training, as well as networking benefits, to both experienced operators and those who have recently entered this rapidly expanding field.
In what year was RETA established?
RETA was organized in 1910 as the National Association of Practical Refrigerating Engineers (NAPRE) — in the year following its first convention in 1909.
The name change to Refrigerating Engineers and Technicians Association was voted on at the National Conference general membership meeting on October 19th, 1961.
What is RETA’s structure as an association?
RETA is governed by a member-elected Board of Directors consisting of a Chairman, President, Executive Vice President, Treasurer, and Second Vice President, plus Directors and National Committee Chairs.
What is the RETA Mission Statement?
To enhance the professional development of industrial refrigeration operating and technical engineers.

What is RETA Certification?
RETA certification requires meeting eligibility criteria and demonstrating knowledge of industrial refrigeration concepts, principles and practices. RETA certification exams and other requirements assess competencies in the realm of industrial refrigeration operation. RETA training materials provide the fundamental knowledge needed to understand these concepts and operating principles.
What is ANSI and why is it important?
RETA is the sole provider of ANSI-accredited certification in industrial refrigeration in the world.
What certification programs does RETA offer?
RETA currently offers two levels of ANSI accredited certification
There is no minimum experience requirement for CARO. The exam assesses mastery of concepts and principles in RETA’s Industrial Refrigeration I and the ammonia safety chapter in Industrial Refrigeration IV (chapter 7).
CARO includes 110 questions and allows three hours for completion.
CIRO measures mastery of applied refrigeration system operations and troubleshooting based on principles and knowledge addressed in RETA books: Industrial Refrigeration (IR) I · IR II (systems) IR IV (plant operation and safety) Basic Electricity (BE) I · Basic Electricity (BE) II (ladder diagrams)
The CIRO exam consists of 135 questions and allows three hours for completion.
Other RETA Credentialing Programs
RETA also provides certification for two additional programs that are not ANSI-accredited.
CRES candidates should be familiar with the operating concepts and principles addressed in IR-1 in addition to energy management strategies and techniques in the Industrial Refrigeration Best Practices Guide published by Cascade Energy and the Energy Conservation Manual – Industrial Refrigeration Consortium published by University of Wisconsin.
The CRES exam consists of 135 questions and allows three hours for completion.There is also a performance aspect related to CRES which includes the documentation of five energy management activities related to refrigeration system operations and their facilities whereby energy savings can be quantitatively documented.
Certification of CRES occurs after successful completion of the exam and documentation of five activities. Additional activities must be documented to maintain CRES certification.
The CRST is designed for technicians and support personnel who troubleshoot and maintain industrial refrigeration plants and facilities. The credential addresses topics from advanced levels of plant safety and operations through the basics of ammonia refrigeration compliance and PSM requirements. A CARO or CIRO credential, or documentation of at least 4 years of progressively responsible experience is required to take the CRST exam.
The RAI exam consists of 85 questions and allows three hours for completion.
How long is my certification valid?
For all RETA certification programs, certification is valid for three years from test passage date or date of last three-year renewal cycle.
How do I renew my certification? What are certification renewal requirements?
RETA certification holders are notified of renewal requirements within one year of renewal date.
A published list of many acceptable training activities is available from the RETA website, Appendix 500A-PDH Table.
PDH earned at the annual RETA national Conference.
There is a fee required at the time of renewal.
Once reviewed and approved at RETA HQ, a new certificate and membership card reflecting updated certification (and expiration date) is issued.
How do I apply to take RETA certification exams?
All RETA certification candidates must begin by submitting a completed certification application to RETA HQ with payment.
After review and approval by RETA, an email notification is issued to the candidate with directions for completing any steps needed to qualify to take the required examination.
A study copy of the examination supplement that includes information that will be required during a test can be downloaded from the RETA website.
Candidates are encouraged to use the required supplement and other test preparation materials on the RETA website to help them prepare for an exam.
After a candidate has met all eligibility requirements and has scheduled an exam, RETA will provide a sealed, secure copy of the appropriate supplement that can only be opened at a RETA-approved test center on the day of a test.

From the link, a candidate may enter existing account information or create a new account to schedule the RETA CARO or CIRO practice exams for a fee.
Practice exam score reports provide direct feedback to reference materials for further study. In recent years, 86% of RETA candidates who completed both the appropriate practice test and the full RETA certification examination have earned a RETA credential.
