RETA TESTING CORNER NO. 16

RETA’s Testing and ANSI Guru

Dr. Ron Rodgers, RETA’s Psychometrician (testing expert) and ANSI Accreditation Manager, has guided development of all RETA credentialing exams since 2002. RETA Testing Corner provides information

also offer candidates experience learning to use the on-screen references for each test. Each practice test requires using the on-screen references they need to take a full RETA examination. These references also appear in the study guide for each test. Study guides can be printed free from Certification screens on RETA’s website. RETA candidates must decide when to use on-screen references during each test. Qualified operators and technicians know when to consult such references to limit an ammonia release or other system emergencies, to prevent injury to themselves or other personnel, and to improve

system safety and efficiency by recommending maintenance and/ or making adjustments in system operations. Candidates should be as familiar with these sources as they are with manuals for equipment in the facilities they operate, service or support. For example, each RETA test asks questions about Safety Standards and Procedures. Some questions are answered in an Ammonia Safety Data Sheet (SDS) in these references. Candidates who score below 70% often answer some of these questions incorrectly because they did not use the SDS effectively during their test.
