Open Book Test

The Oklahoma Limited Electrical Contractor examination is an open book test. Approved references may be brought into the testing center according to PSI examination rules.

PSI permits approved reference materials to be highlighted, underlined, and indexed before testing. Permanent tabs are allowed. Temporary tabs such as Post-it notes are not permitted and must be removed before the examination begins.

This makes highlighted and tabbed references particularly useful for candidates who want to build an organized open-book study routine. Highlighting can draw attention to important material, while tabs can help candidates move to commonly used NEC articles and technical subjects more efficiently.

Open book does not mean the examination can be completed by simply searching the NEC for every answer. With 100 scored questions and 240 minutes, candidates need to recognize the subject of a question, decide whether a reference lookup is necessary, and identify the most appropriate source.

The 2023 National Electrical Code is the primary reference for many technical questions. Candidates should learn how the NEC is organized and become familiar with its index, chapters, articles, definitions, tables, and informational structure.

Ugly's Electrical References can support preparation involving electrical formulas, Ohm's law, electrical power, conductor information, motors, transformers, conversions, and practical calculation references. It can be useful when reviewing electrical relationships alongside NEC requirements.

OSHA 29 CFR Part 1926 supports safety-related preparation. Candidates should become familiar with how the federal construction regulations are organized so they can locate safety provisions efficiently when required.

A useful open-book study method is to work through a practice problem without immediately opening a reference. First identify the subject. Next determine whether the NEC, Ugly's Electrical References, or OSHA material is the appropriate resource. Then perform the lookup. This approach develops both electrical knowledge and reference-selection skills.
