Massachusetts Electrician & Plumber Exam Prep
Massachusetts contractors are licensed by the Massachusetts Board of State Examiners of Electricians & Board of Examiners of Plumbers and Gas Fitters. Use the classification list below. Some states fold business questions into the trade exam. We do not sell a standalone Law & Business paper for Massachusetts.
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 We do not publish a single Q-count for every classification on this page, and we do not guarantee a passing result.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 Massachusetts
Massachusetts licenses through the Board of State Examiners of Plumbers and Gas Fitters and the Board of State Examiners of Electricians. The distinguishing feature of Massachusetts is classroom theory: field hours alone will not qualify you, at any level.
- Apprentice plumber: register with the Board first. An apprentice must be at least 16 years old, licensed by the Board, and learning and working at plumbing under the direct supervision of a master or journeyman plumber while employed by a master plumber. Unregistered hours do not count.
- Journeyman plumber: three years plus 300 hours of theory. Work three years as an apprentice, complete 300 hours of plumbing theory at an institution approved by the Department of Education and the Board, then pass the journeyman examination.
- Master plumber: one year plus 100 hours of advanced theory. Work a minimum of one year as a journeyman, complete 100 hours of advanced plumbing theory, then pass the master plumber examination.
- Know which licence you are sitting for. The Board examines five separate categories: Journeyman Plumber, Master Plumber, Journeyman Gas Fitter, Master Gas Fitter and Undiluted Liquefied Petroleum Gas Installer. Gas fitting is a distinct credential from plumbing — holding one does not confer the other.
- Systems technician: 4,000 hours over at least two years. On the electrical side, systems technician licensure requires 4,000 hours of work across a minimum of two years under a licensed Massachusetts systems technician or journeyman electrician.
- Systems contractor: the licence, a year, and 75 hours of study. Requires a Massachusetts systems technician licence, at least one year of work experience, and 75 hours of Board-approved education.

Massachusetts contractor licensing — FAQ
Who licenses building contractors in Massachusetts?
The Massachusetts Board of Building Regulations and Standards (BBRS) issues the Construction Supervisor License (CSL), which authorizes supervising most building projects. Electricians and plumbers are licensed by their own separate state boards.
What is the Massachusetts CSL exam?
An open-book exam on the Massachusetts building codes: the Unrestricted CSL is 75 questions and the Restricted CSL is 60 questions, each with a three-hour limit and a 70% passing score.
What experience does the Massachusetts CSL require?
At least three years (about 4,500 hours) of experience in the construction, reconstruction, alteration, repair, or demolition of buildings. The CSL renews every two years with 12 continuing-education units.
What should I study for the Massachusetts CSL?
The Massachusetts building code, the International Building Code (IBC), and the Residential Code. Because the exam is open book, fast, well-tabbed code navigation is the decisive skill.
How long should I study for the Massachusetts exam?
Most candidates do well on a 30-, 60-, or 90-day plan depending on experience, which is why we offer access at all three terms ($99 / $129 / $169). Each guide includes a day-by-day study plan.
