One exam, 100 questions
You need 70% overall. Calculations sit inside the outline areas rather than in a separate portion, and our full-length practice exam draws from each area in the same proportions.

On the 2023 NEC — ahead of Louisiana’s own code
Louisiana enforces the 2020 NEC and has proposed moving to the 2023 edition on January 1, 2027, but the PSI exam already tests the 2023 NEC. Study material written for the 2020 edition numbers these rules differently. Every question here cites the 2023 section.
| Topic | 2020 NEC | 2023 NEC |
|---|---|---|
| Non-dwelling general lighting unit loads220.42 | Table 220.12 | Table 220.42(A) |
| Lighting load demand factors220.45 | Table 220.42 | Table 220.45 |
| Non-dwelling receptacle demand factors220.47 | Table 220.44 | Table 220.47 |
| EV charging load in a load calculation220.57 | No rule | 7,200 VA or the nameplate, whichever is larger |

Frequently asked questions
How is the Louisiana Electrical Statewide exam structured?+
One PSI trade exam of 100 questions in 4 hours, open book, and you need 70%. Up to 10 unscored experimental questions may be added, and they do not count against your time. The 13 areas range from grounding, services and special occupancies (10 questions each) to low-voltage and alarm systems (2).
Which code edition is the exam on?+
The 2023 NEC, and code questions are based only on that edition. Louisiana still enforces the 2020 NEC; the state code council has published a notice of intent to adopt the 2023 NEC, with Louisiana amendments, from January 1, 2027. The exam outline names the 2023 NEC as NFPA publishes it, so our questions use the unamended code.
Is it open book? What can I bring?+
Yes, with three books: the 2023 NEC, 29 CFR 1926 (the OSHA construction standards, or PSI's selections from them) and Ugly's Electrical References, 2011, 2014 or 2017 edition. Highlighting, underlining and indexing must be done beforehand, with permanent tabs only. Only a silent, non-programmable calculator is allowed — no scientific calculators.
Who needs this license?+
Any company doing electrical work on a project worth $10,000 or more, labor and materials, residential or commercial. The license belongs to the company; its qualifying party — an owner, officer or full-time employee — is the person who passes the exam. Louisiana has no statewide journeyman or master electrician license; those are issued by cities and parishes, and a statewide licensed electrical contractor and its employees are exempt from local exam requirements.
Is there a business and law exam too?+
Yes, but it is not a PSI exam. One qualifying party per license completes LSLBC's online Business and Law course, about an hour long with an exam at the end, for $150.
What does it cost, and what if I fail?+
The PSI exam fee is $140. If you fail, you wait 30 days to retake it; LSLBC publishes no attempt limit. Your eligibility lasts one year, after which you reapply with LSLBC.
What do I need before I can apply?+
LSLBC publishes no years-of-experience requirement for the Electrical classification. The company needs a financial statement showing a net worth of at least $50,000, or a letter of credit instead, and a background check of its principals and qualifying parties. Commercial licenses carry no continuing education requirement.
