To become a journeyman in a skilled trade, you complete a registered apprenticeship, pass a trade-specific licensing exam, and file an application with your state’s licensing board. The federal floor for the apprenticeship is 2,000 hours of on-the-job learning, but most electrical and plumbing programs run four to five years and require 8,000 hours of supervised field work before you’re eligible to test. Along the way you log classroom instruction, document every hour under a licensed supervisor, and finish with a Certificate of Completion of a Registered Apprenticeship — the document that anchors your license application.
Hours and Classroom Instruction You Need
The federal framework in 29 CFR 29.5 sets the minimum at 2,000 hours of on-the-job learning under the time-based approach.1eCFR. 29 CFR 29.5 – Standards of Apprenticeship That is a floor. Electrical apprenticeships typically require 8,000 or more field hours over four to five years, and plumbing programs fall in a similar range, with some requiring closer to 6,000 hours depending on the jurisdiction.
The same regulation recommends at least 144 hours of related technical instruction per year.1eCFR. 29 CFR 29.5 – Standards of Apprenticeship Although the word used is “recommended,” most registered programs treat it as a hard requirement.2U.S. Department of Labor. National Guidelines for Apprenticeship Standards – International Union of Painters and Allied Trades Finishing Trades Institute Over four years, that is 576 classroom hours. For electricians, the subject matter covers circuit design, load calculations, and code compliance. For plumbers, it covers drainage systems, water supply design, and fixture installation.
Your program will track every hour. When you finish, the sponsor submits documentation to the Department of Labor or your state apprenticeship agency, and you receive your Certificate of Completion of a Registered Apprenticeship.3Apprenticeship.gov.

You’ll submit it with your license application and may need it again for interstate work later in your career.
Credit for Military Service
If you picked up trade skills on active duty, you may be able to credit that time against your apprenticeship hours. The United Services Military Apprenticeship Program (USMAP) awards pre-registration credit at 1,000 hours for each full year since you completed military occupational specialty training, provided at least one full year has passed before you enroll in the trade. The credit tops out at 50% of the trade’s required hours and will not reduce any program below the 2,000-hour federal minimum.4United Services Military Apprenticeship Program. USMAP – Frequently Asked Questions
Separated before finishing USMAP? Request a Letter of Participation documenting the hours you did log. Registered Apprenticeship employers can choose to grant credit for that prior experience. For a veteran with three qualifying years applying to an 8,000-hour electrical program, that credit could shave off 3,000 hours — roughly a year of training.
Applying to Your State Licensing Board
Paperwork is where most applicants lose time. You will need work history affidavits proving your hours were completed under a licensed professional, signed by the employer or supervising journeyman. You will need official transcripts from your vocational school or union training center. You will need your Certificate of Completion. All of this cross-references the application form from your state licensing board, which asks you to break your experience into categories the board defines.
Most boards now accept electronic filing to speed verification. The application fee is non-refundable and generally runs $75 to $200 depending on the trade and jurisdiction. Mailed applications typically require a certified check. Expect a processing window of 30 to 90 days while the board verifies signatures, checks your school’s accreditation, and reviews the file for completeness. Approved applicants receive formal notification followed by a physical license mailed to the address on file. Keep a copy accessible once it arrives; failing to produce a valid license during a job-site inspection can trigger immediate work stoppages and administrative penalties.
Background Check and Fingerprinting
A growing number of states require fingerprinting and a criminal background check. Prints are typically run against both state and FBI databases, and some states will not issue a license until both results return. That can add weeks to processing.
A record is not an automatic disqualification. Boards generally weigh the nature of the offense, how much time has passed, and evidence of rehabilitation, with closer scrutiny when the offense relates to the trade (financial fraud for a contractor, for instance). Disclose accurately. Failing to report a conviction that the background check uncovers is often treated as its own ground for denial, even when the underlying offense might not have been disqualifying.
Passing the Licensing Exam
Once your application clears, you register for the trade exam. Electricians are tested on the National Electrical Code (NFPA 70). Plumbers face the Uniform Plumbing Code or the International Plumbing Code, depending on the jurisdiction. Exams typically run three to four hours and consist of multiple-choice questions covering safety protocols, calculations, installation methods, and code navigation.
Most testing centers let you bring the relevant code book into the room, but it must be unmarked: no highlighting, no handwritten notes, and in some jurisdictions no adhesive tabs beyond those the publisher included. An 800-page code book under time pressure is its own skill. Practice navigating it before exam day; speed of lookup matters as much as recall.
Exam fees generally run $100 to $150, paid directly to the testing provider and separate from your application fee. Fees are non-refundable even if you fail. Most states allow retakes after a waiting period, but you typically pay the exam fee again each attempt.
The NASCLA Option for Portability
The National Association of State Contractors Licensing Agencies offers a standardized journeyman electrician exam that participating states accept in place of their own trade test. Passing results are stored in the National Examination Database, which lets you share transcripts electronically with licensing agencies in any participating state.5National Association of State Contractors Licensing Agencies. NASCLA Electrical Exams You still have to meet each state’s application requirements, fees, and any supplemental local-code testing, but you avoid retaking the main trade exam. The NASCLA application fee is $65, separate from any testing-center charges.6National Association of State Contractors Licensing Agencies. Apply for NASCLA Exams If you expect to work across state lines, taking the NASCLA exam from the start is worth considering; retrofitting portability later means sitting for it as a separate test on top of the state-specific one.
What the License Lets You Do
Journeyman status gives you the legal authority to perform complex installations and repairs on your own technical judgment, without supervision. It also authorizes you to supervise apprentices, which means you carry accountability for the accuracy and safety of their work in addition to your own.
The authority has limits worth knowing before you plan around it. Journeymen are generally prohibited from pulling municipal permits for new construction or running their own independent contracting business. Those belong to master-level license holders and licensed contractors. You can perform the work, but someone with a higher credential must hold the contract and the permit. Side work under your own name without the appropriate contractor or master license exposes you to significant fines and, in some states, criminal charges.
Keeping the License Active
The license is not a one-time achievement. Most states run a two- to three-year renewal cycle, and letting the license lapse past the grace period can force you to retake the exam from scratch in some jurisdictions.
Renewal usually requires continuing education from approved providers. Hour requirements vary from roughly 4 to 24 hours per cycle depending on trade and state, with course topics tracking recent code updates, new safety standards, and emerging technologies. Some states also require minimum work hours during the period to show you’ve stayed active. Base renewal fees typically run $45 to $150, with late fees stacking on top. If you’ve lapsed long enough that re-examination is required, you’re paying the exam fee again plus a new application. The deadline compounds if you ignore it, so treat it accordingly.
