2021 RETA Breeze September-October

Candidates can expand the right side of the screen by moving the centerline to the left. This sample screen also shows the Fire Fighting Measures section of the Ammonia Safety Data Sheet (SDS) where the answer to the sample question appears. “Carbon dioxide can displace oxygen” parallels answer A in the sample question. Three navigation buttons appear on the far right side of the screen. The top button fits the image to the width of the window on the right side of the screen. The + and – icons zoom in or out. The CTRL key + Mouse scroll wheel also can be used to zoom in or out. RETA encourages all candidates to be as familiar with the references in their study guides as they should be with manuals for the refrigeration systems they work with and support on the job. Just as candidates must know when to refer to a manual or other resources when a problem occurs on the job, questions on RETA exams do not indicate when a candidate should use information in these onscreen references. RETA exams require that each candidate must decide when to consult these references.

Candidates who want to take additional practice tests can do so for $59 per attempt. These can be purchased from the RETA online store. These navigation tools appear in the onscreen references for all RETA exams given in test centers. Similar screens and images appear in remotely proctored CARO, CIRO and CRST exams that are taken in online-proctored (OLP) tests. Similar screens are shown in the application for RETA OLP exams. OLP exams use external webcams and strict test security procedures that closely parallel those in test centers. OLP exams can be taken from home. See RETA’s OLP application for more details.
