Electricians are trained to one of three levels: Apprentice, Journeyman, and Master Electrician.Journeymen are electricians who have completed their Apprenticeship and who have been found by the local, State, or National licensing body to be competent in the electrical trade.
While certification is optional in some areas, there is one type of national certification mandated by the Environmental Protection Agency (EPA) for anyone working with refrigerant recovery and recycling (which includes virtually all HVAC technicians).
The CRCST certification program is designed to recognize entry-level and existing technicians who have demonstrated the experience, knowledge and skills necessary to provide competent services as a Sterile Processing technician.
Master Electricians have performed well in the trade for a period of time, often seven to ten years, and have passed an exam to demonstrate superior knowledge of the National Electrical Code, or NEC.
The National Institute for Automotive Service Excellence (ASE) is a professional certification group that certifies professionals and shops in the automotive repair and service industry.
