The refrigeration industry has a variety of competency exams and certification tests for technicians. Taking these exams can be beneficial because they can help identify areas of weakness or strength and allow technicians to gauge their understanding of the equipment they service. They also help to demonstrate their commitment and focus on becoming a better technician.
Technicians taking certification exams should not do so lightly. Most technicians will need to do some type of preparation, as many exams cover a lot of theory. A good idea is to take plenty of practice tests whenever possible. These free practice exams will generally not have the exact questions as the real exam, but they serve as a benchmark. Also, do not wait until the last minute to study. We all live busy lives, and sometimes there is simply not enough time in a day to get everything done. But if you are serious about passing these exams, you need to study and be ready.
