4-Year Electrical Apprenticeship Program

Traditional Classroom Instruction

Apprentice at work

Our intensive four year apprenticeship training program is designed to provide an electrical apprentice with the necessary theory and practical training to earn the status of electrician.

An electrician is a highly skilled tradesperson, who combines electrical theory, knowledge of electrical equipment, and the necessary job skills to safely and correctly perform services which enable consumers to utilize electrical, low voltage and renewable energy for such purposes as lighting, heating, operation of electrical equipment, motor control systems and appliances.

Taking place as traditional classroom instruction, and our oldest and most populated program, the IEC Chesapeake 4-Year Electrical Apprenticeship Program is based on the IEC Nationally approved USDOL Curriculum. Our program has the distinction of being one of few programs that focuses heavily on solar and other renewable energies in the 4th year.

Most of our students enroll with the ambition of earning their Journeyman or Master Electricians License, and many of our students go on to become Project Managers, Foremen, Estimators, and upper management.
