Electrician exam prep
Mississippi electrical contractor license: the NASCLA exam route
The Mississippi State Board of Contractors licenses commercial electrical contractors under its Electrical classification. PSI’s bulletin accepts the NASCLA Accredited Examination for Electrical Contractors instead of the state Master Electrician trade exam, and every applicant also passes the Law and Business Management exam.

Before you book
- The state Master Electrician exam is on the 2020 NEC (80 questions, 3 hours, 70%). The NASCLA exam allows the 2020 or 2023 NEC; our practice exam uses 2023.
- The Law and Business Management exam is still required; this practice exam does not cover it.
- Residential electrical contractors take a separate Residential Electrician exam, and the state Master Electrician exam is the other commercial route; both have their own practice exams on the Mississippi page.
- NASCLA changes the exam’s content outline on January 1, 2027. Our practice exam is weighted to the 2027 outline; exams taken through December 31, 2026 still follow the older one, which puts more weight on project management, safety and theory.
