How the real exam is built
The real exam: 60 questions across 9 areas in 3 h. Our timed exams use the same areas and weights.
You need 70% (42 of 60). These are the question counts in PSI’s bulletin; PSI may add a few unscored experimental questions, which count against your time. Our full-length practice exam draws from each area in the same proportions, on the 2020 NEC, Ugly’s and OSHA; it does not cover the International Residential Code (IRC), which is also on PSI’s reference list.

About the Mississippi Residential Electrician (Residential Electrical Contractor)
Granted by Mississippi State Board of Contractors (MSBOC)
Mississippi State Board of Contractors Residential Electrician trade exam (PSI): 60 questions in 3 hours, open book on the 2020 NEC, the IRC, Ugly's and 29 CFR 1926, 70% to pass.
Eligibility Requirements
No set number of years. The residential application shows experience in residential electrical work (at least three completed jobs), three reference letters including one from your bank, a certificate of general liability insurance (no minimum amount), workers’ compensation coverage if you have five or more employees, and proof that the qualifying party works for the company. The Board makes you eligible with PSI once the application is in.
On the 2020 NEC
PSI’s Mississippi bulletin lists the 2020 NEC for both electrical trade exams and says code questions are based only on the edition listed. No change has been announced. Much current study material is written for the 2023 NEC, which moved these rules. Every question here cites the 2020 section:
| Topic | 2023 NEC (newer study material) | 2020 NEC |
|---|---|---|
| Dwelling general lighting load (3 VA per ft² in both)220.14(J) | 220.41 | 220.14(J) |
| Non-dwelling general lighting unit loads220.12 | Table 220.42(A) | Table 220.12 |
| Lighting load demand factors220.42 | Table 220.45 | Table 220.42 |
| Non-dwelling receptacle demand factors220.44 | Table 220.47 | Table 220.44 |
| EV charging load in a load calculationArticle 220 | 7,200 VA or the nameplate (220.57) | No such rule |

Keeping Your Certification Active
Renewal requirements
- Cycle
- Every year. The Board emails a reminder about 60 days ahead; renewal needs current liability insurance, and a license expired more than 180 days needs a new application
Reciprocity
The Board’s reciprocity list names the South Carolina Residential Builders Commission’s Residential Electrical license, and it has electrical agreements with Alabama, North Carolina, Ohio and Tennessee and accepts Louisiana exam scores. Each covers different classifications, so ask the Board; a waiver never covers Law and Business Management.

Frequently asked questions
How is the Mississippi Residential Electrician exam structured?+
One PSI trade exam of 60 questions in 3 hours, open book, and you need 70% (42 correct). Services, feeders and branch circuits (15) and general electrical knowledge (13) make up almost half. Then grounding and bonding (6), overcurrent protection (5), conductors and cables (5), and 4 each on raceways and boxes, lighting, specialty installations and safety.
Is it open book? What can I bring?+
Yes. The references are the 2020 NEC, the 2021 International Residential Code, Ugly’s Electrical References (2017) and OSHA’s construction standards (29 CFR 1926). You may highlight, underline and add permanent tabs, but not write in the books; Post-it tabs and loose papers are not allowed. Bring a silent, non-programmable calculator.
Does the practice exam cover the IRC?+
No. Our questions come from the 2020 NEC, Ugly’s and 29 CFR 1926. The IRC’s electrical chapters largely restate NEC rules for one- and two-family dwellings, but if a question turns on the IRC’s own wording, look it up in the 2021 IRC you bring to the exam.
Who needs this license?+
Any subcontractor doing residential electrical work on a residential construction or improvement project in Mississippi must hold the Board’s residential license with the Residential Electrical classification, which covers residential electrical work only. Commercial electrical work of $50,000 or more needs the commercial Electrical classification and the Master Electrician (or NASCLA) exam instead. Individual electrician cards are issued by cities and counties, not the state.
What do I need before I can sit the exam?+
Apply to the Board first. The residential application ($50, which includes one trade classification) needs at least three completed residential electrical jobs, three reference letters (one from your bank), a certificate of general liability insurance (no minimum amount for residential), workers’ compensation coverage if you have five or more employees, and proof that the qualifying party works for the company. The Board then tells PSI you are eligible.
What does it cost?+
PSI charges $120 per exam ($240 for the trade exam and Law and Business Management together). The Board’s residential application fee is $50, and the license renews every year for $100 ($110 once expired).
Does Mississippi waive the trade exam for licensees from other states?+
For some. The Board’s reciprocity list names the South Carolina Residential Builders Commission’s Residential Electrical license, and it has electrical agreements with Alabama, North Carolina, Ohio and Tennessee and still accepts Louisiana exam scores. Each agreement covers different classifications, so ask the Board whether yours covers residential electrical. A waiver covers the trade exam only, never Law and Business Management, and costs $50 per exam. Mississippi also recognizes out-of-state licenses under its Universal Recognition of Occupational Licenses Act and for military families.
Which code edition is the exam on?+
The 2020 NEC. PSI’s bulletin lists it for both electrical trade exams and says code questions follow only the listed edition, which is also the only edition allowed in the test room. No move to the 2023 NEC has been announced. Every question here cites the 2020 section, so if your study material is on the 2023 edition, watch the rules that moved, such as the load-calculation tables.
Do I also take a Law and Business Management exam?+
Yes. Every Mississippi applicant, commercial or residential, passes Law and Business Management: 50 questions in 2 hours, 70% to pass, open book on the NASCLA Contractors Guide to Business, Law and Project Management, Mississippi 6th edition. It is a separate exam that we do not cover yet; our practice exam is the trade exam only.
How many times can I take it?+
As often as you need within 6 months of the Board making you eligible: PSI allows unlimited retakes in that window, at $120 per attempt. If you have not passed after 6 months, you reapply to the Board.
Where do I take the exam?+
At a PSI test center. PSI’s Mississippi center is in Jackson, and Mississippi candidates can also test at PSI centers in Baton Rouge, New Orleans, Shreveport, Huntsville, Birmingham, Montgomery, Mobile and elsewhere. No remote option is offered. Cancel or reschedule at least 2 days ahead to keep your fee; call PSI at (855) 557-0619 or use its website.
What is the pass rate?+
Neither the Board nor PSI publishes pass rates for Mississippi’s electrical exams.
