This Master/Journeyman Electrician Course consists of 32 classroom hours to help you
pass the PSI Exam.
This electrical training course was designed to bring students up to speed on their
knowledge of the National Electrical Code® as quickly and efficiently as possible. It also
teaches students working in industrial and commercial facilities how to navigate, use and
understand the NEC® as it applies to the electrical work they do. Inspectors and
residential electricians will also find this course extremely valuable. During this unique
training program the NEC’s® most recent changes are addressed as well as the students’
specific work situations and most challenging code questions.
Overall, this class is designed to help electrical workers make practical use and
application of the important standards found in the National Electrical Code®.
Registration is $400.00. We require a $50 deposit; the balance of $350.00 is due the first
morning of the class. We CANNOT GUARANTEE that you will pass the Electrical
License Exam, but we do GUARANTEE that you will gain additional knowledge during
this class that will assist in passing the Electrical License Exam.
The registration fee includes the Exam Preparation Workbook and practice exams. If
you haven’t already purchased, you will need a copy of the 2011 NEC®.
For qualifying the PSI exam, you need experience verification/approval from State of
Virginia Licensing Board (DPOR); please check the State website www.dpor.virginia.gov
All fees and registration are non-refundable
