NOTICE: As of 11/1/24, there appears to be an NEC version conflict between the bulletin accessed from the PSI web site vs the version downloaded from the "Testing Vendor PSI" link on the Oklahoma CIB site on the "Testing / Exam Information" page. In the PSI site version, they have added in red text under the "REFERENCE LIST" of all electrical exams that the 2023 version is current and that 2020 version will not be used after December 15th, 2024.
The books listed below are NOT allowed at the exam location
We highly recommend that you purchase one of the reference books above to study for your exam. Each book is a comprehensive subject index to the NEC. They provide an even faster way to look up answers in the code and are far more detailed than the index at the end of the code book.
A practice exam is currently NOT AVAILABLE
