Search for an electrician school that offers a full course of electrical classes and teaches to the National Electrical Code (NEC) standards. The school should provide training for becoming a helper, journeyman and master electrician and teach all phases of electrical work, including commercial, residential and industrial.
The NEC standards are the only set of electrical standards that are agreed on in all 50 states. All reputable electrician schools teach to these standards, with the requirement that a test on the NEC be passed before a certificate can be obtained.
In addition, to fulfill the standards needed to receive and hold an advanced electrician's license, students need to be employed in the electrical field for a specific amount of hours. Electricians with no experience are supplied with a helper's license. After finishing the course work required, passing an electrical code test and having 4,000 certified hours of work under the supervision of a Master electrician they are eligible for a Journeyman's license.
More courses are required to move beyond this level, and an additional 4,000 hours of employment is needed to finally become licensed as a Master Electrician. To continue to hold this license, all electricians are required to take an eight-hour update course. This can vary by state but is typically required every two or three years.
