An occupation sharing qualities with that of the engineer and the technician. Technologists design, but are often involved in a more hands-on way than engineers are. Technologists often assist or work alongside engineers and technicians. Technologists specialize in fields such as computers, mechanics, electronics, controls, and other technology-related industries.
I'm not sure about other countries/states, but in Ontario, in order to use the designation "Technologist", "CET", or "Certified Engineering Technologist", you must be a member of OACETT (Ontario Association of Certified Engineering Technicians and Technologists). In order to be a member you must be a graduate of an acknowledged technology program, and you must pass the membership exam.
