NASCLA examination applications are submitted through the NASCLA National Examination Database. An approved application is valid for one year from the approval date. Candidates receive examination scheduling information after the application is processed.

The NASCLA examination is intended to provide a standardized trade examination that can be accepted by participating jurisdictions. Tennessee's acceptance of the Journeyman Electrician examination means the passing NASCLA result can be used within the applicable Tennessee licensing process, subject to the requirements established by the licensing authority.

Open Book Test

The NASCLA Accredited Journeyman Electrician examination is an open book test. Candidates may use authorized reference materials according to the examination rules in effect for their testing appointment.

An open-book electrical examination still requires substantial preparation. With 100 scored questions and multiple technical references, candidates cannot depend on searching every answer from the beginning. Successful preparation should focus on understanding electrical concepts while also developing familiarity with the organization of the books.

The 2023 National Electrical Code should be used throughout your study program. Practice navigating the NEC index, Article 100 definitions, chapters, articles, tables, informational notes, and cross-references. Become familiar with where major subjects are located so that code searches become more deliberate.

Use the safety references regularly as well. OSHA 29 CFR Part 1926 focuses on construction-industry safety requirements, while OSHA 29 CFR 1910 addresses general-industry workplace standards. NFPA 70E provides material specifically related to electrical safety in the workplace.

NFPA 72 supports preparation involving fire alarm and signaling systems. Ugly's Electrical References provides formulas, tables, calculations, and practical technical information, while Understanding Electrical Theory for NEC Applications reinforces the electrical principles that support code calculations and installation requirements.

When working practice questions, identify the subject first. Decide which reference is most likely to contain the relevant information, navigate to the appropriate section, and then confirm the answer. Repeating this process can help build a more efficient open-book testing routine.

Licensing Steps

Passing the NASCLA Journeyman Electrician examination does not automatically issue a Tennessee license. NASCLA examination results are used as an accepted trade-examination credential, while Tennessee and applicable licensing authorities retain control over licensing qualifications and approvals.

1. Determine the Tennessee licensing classification or jurisdiction that applies to your work. Electrical licensing requirements can depend on the type, value, and location of the work being performed.
2. Apply for the NASCLA Journeyman Electrician examination. Submit the NASCLA examination application through the National Examination Database.
3. Prepare for the examination. Study the 2023 NEC, electrical theory, safety, wiring and protection, wiring methods, troubleshooting, equipment, special occupancies, and communication systems.
4. Schedule and take the examination. Follow the examination scheduling instructions provided after your NASCLA application is approved.
5. Achieve the required passing score. The current NASCLA Journeyman Electrician examination requires a minimum score of 70.
6. Submit the NASCLA examination result as required. Passing results are stored in the NASCLA National Examination Database and can be transmitted to participating agencies through the NASCLA transcript process.
7. Complete applicable Tennessee licensing requirements. Submit the appropriate licensing application and satisfy any additional business, financial, experience, examination, or classification requirements that apply.
8. Follow local requirements when applicable. Electrical licensing and permitting requirements may also involve local authorities depending on the work and jurisdiction.

State Requirements

The Tennessee Board for Licensing Contractors regulates contractor licensing in Tennessee, including electrical contractor classifications. Tennessee contractor licensing requirements apply when work falls within the scope and project-value thresholds established by state law.

Tennessee requires a contractor license before bidding, negotiating, or performing qualifying construction work when the total project cost is $25,000 or more. Electrical work is included within the types of construction activity regulated by the contractor licensing law.

Tennessee's contractor classification system includes the Electrical Contracting (CE) classification. The full CE classification covers electrical work for buildings and structures, and Tennessee identifies a trade examination requirement for the classification. Tennessee also maintains several electrical subcategories, some of which have separate examination requirements.

NASCLA lists the Tennessee Board for Licensing Contractors as accepting the Journeyman Electrician examination. The state also participates in the Electrical Contractor/Master Electrician examination program. Candidates should distinguish between passing a NASCLA electrical examination and obtaining a contractor license because the examination itself is not a license.

Passing NASCLA places the examination result in the National Examination Database. Participating regulatory agencies can receive the candidate's transcript through the NASCLA system and combine that examination record with the appropriate licensing application.

Tennessee contractor applicants may also have separate Business and Law examination requirements depending on the licensing pathway. Beginning July 1, 2026, Prov became the Tennessee Board for Licensing Contractors' new trade examination provider for state-administered contractor examinations.

The licensing authority determines whether an applicant has satisfied the applicable classification, business, financial, examination, and application requirements. Candidates should therefore treat NASCLA exam preparation as one component of the broader Tennessee licensing process.

Test Information and Study Materials

A productive Tennessee NASCLA Journeyman Electrician study plan should combine National Electrical Code navigation with electrical theory, safety, troubleshooting, calculations, and practical installation knowledge. Because the examination contains ten content areas, a balanced approach is more useful than focusing on one subject exclusively.

Begin with Wiring and Protection. This category contains 18 scored questions and represents the largest section of the examination. Review branch circuits, feeders, services, conductor protection, grounding and bonding, overcurrent devices, and related code requirements.

Wiring Methods and Materials accounts for 16 scored questions. Practice working with conductor types, raceways, cables, boxes, fittings, installation conditions, and other wiring-method requirements. Learn which NEC articles apply to specific installations and how general rules interact with product-specific requirements.

General Code Requirements contains 15 questions. Develop familiarity with fundamental NEC organization, terminology, working space, installation requirements, definitions, and other provisions that apply across multiple electrical systems.

Electrical Theory and Principles accounts for 10 questions. Review voltage, current, resistance, power, series and parallel circuits, alternating current, conductors, transformers, motors, loads, and common electrical calculations. Understanding why formulas work can make it easier to solve questions presented in unfamiliar formats.

Testing and Troubleshooting contains 7 questions. Practice interpreting voltage, resistance, current, continuity, circuit conditions, and test-instrument results. Journeyman electricians need a systematic approach to identifying electrical problems rather than relying on trial and error.

Basic Electrical Safety contains 8 questions. Use OSHA 29 CFR Part 1926, OSHA 29 CFR 1910, and NFPA 70E to review jobsite hazards, electrical workplace safety, and safe-work practices.

Interpreting Plans and Specifications should also be part of your preparation. Practice identifying electrical symbols, circuits, equipment, layouts, and installation requirements from plans. The ability to translate plans into compliant field work is an important journeyman-level skill.

Special occupancies, special equipment, communication systems, and fire alarm systems should not be ignored. These areas contain fewer questions than general wiring topics, but unfamiliar code sections can take significant time to navigate if you have not practiced with them beforehand.
