New Jersey Electrical Contractor & Master Plumber Exam Prep
New Jersey contractors are licensed by the New Jersey Board of Examiners of Electrical Contractors & State Board of Examiners of Master Plumbers. Most classifications sit a trade paper plus Law & Business. Need only the business paper? It is sold standalone. If you buy a New Jersey classification that sits that exam, that paper is 75% off where we offer it.
Confirm question count, time, open-book rules, and passing score on the live board bulletin before you sit. We do not publish a single Q-count for every classification on this page, and we do not guarantee a passing result.

How to get licensed in New Jersey
New Jersey draws a sharp line between registration and licensure. Home improvement contractors register with the Division of Consumer Affairs; master plumbers and electrical contractors are examined by their own State Boards, and those boards demand a formal apprenticeship.
- Home improvement work requires registration, renewed annually. No person may offer or engage in the business of making or selling home improvements without registering with the Division of Consumer Affairs, and every contractor must register annually on the division’s form.
- Carry the required insurance. Registrants must provide proof of commercial general liability insurance of at least $500,000 per occurrence, plus workers’ compensation insurance unless exempted by law.
- Master plumber: a four-year apprenticeship plus a journeyman year. An applicant at least 21 years old must show either a four-year US Department of Labor-approved apprenticeship including propane services education, followed by one year (at least 1,200 hours) of hands-on experience as a journeyman plumber in New Jersey — or a bachelor’s degree in mechanical, plumbing or sanitary engineering from a regionally accredited institution including propane services education, followed by one year as a New Jersey journeyman plumber.
- Electrical contractor: the same shape, then a three-part exam. Applicants must show completion of the four-year US DOL-approved apprentice programme followed by one additional journeyman year, and must pass a three-part examination.
- Electrical contractors renew on a triennial cycle. Licensees renew every three years and must complete the Board’s continuing education requirement, including Code and New Jersey law components, before renewing. Confirm the current hour totals with the Board of Examiners of Electrical Contractors.
