Do CROs go through the same exact trainings as PJs?

No, they are not paramedic certified. Also a PJ you are expected to be proficient in many aspects, such as extrication, ropes, and over all Technical Rescue Specialist. CROs are not necessarily expected to know every detail like a PJ should, they should just be aware enough to recognized safe and unsafe conditions. A CROs main focus is the up and out aspect.
