Journeyman & Master Electrician Licensing in Oklahoma

The Journeyman & Master Electrician licenses represent two major career levels for electricians in Oklahoma. A Journeyman Electrician is qualified to install, maintain, and repair electrical systems under state regulations.

Both exams focus heavily on the National Electrical Code, calculations, and safety practices. Because these exams are detailed, exam prep is strongly recommended.

Unlimited Journeyman Electrical License

The Unlimited Journeyman Electrical license allows electricians to work on electrical systems without voltage or scope limitations.

This license demonstrates advanced electrical knowledge and is often required for larger or more complex projects.

Because the exam is challenging and code-heavy, exam prep can significantly improve pass rates.
