2020 before the change to 44% in the first three quarters of 2022. Pass rates improved in six of eight content areas by from one to 15 points. These results are shown in the accompanying chart. CIRO candidates in 2022 who took the CIRO Practice Test achieved a pass rate of 68%. Those who did not take the CIRO Practice Test had a pass rate of 63%. RETA recently added another resource to help CIRO candidates prepare. The CIRO Study Guide asks 28 questions about data in a sample screen showing normal and abnormal operations in a refrigera tion system plus eight questions based on an electrical diagram. A new resource on the website explains how to answer these questions and why the information matters in system operations. These policies and resources reflect RETA’s mission statement “to enhance the professional develop ment of industrial refrigeration operating and technical engineers.” RETA created CARO and CIRO to improve the health and safety of all operators, employees and the public in and near the refrigeration facilities where they work. CARO and CIRO are the first steps to help operators demonstrate that they have the knowledge and skills to manage safety and efficiency in and around these facilities.
