Apprentice – Journeyman – Master

Would you like to become a licensed plumber? Becoming a plumber is a two-pronged process that includes practical training and study. In Massachusetts, a hopeful plumber begins an apprenticeship program to receive technical education and complete the required hours of on-the-job training under a licensed master plumber.

To work independently, a plumber is required to receive a license. An applicant will not receive credit for work experience and education unless they were completed in conjunction with one another as measured by calendar years. For each year in which an apprentice obtains 110 clock hours of education, that apprentice must accrue 1700 clock hours of qualifying work experience with some exceptions:

  • An unlicensed individual may complete Tier I of the education requirement prior to obtaining an apprentice license.
  • A licensed apprentice may complete Tier I and Tier II in a single calendar year.
  • In the event that an apprentice is enrolled in a tier but loses their employment, they shall be permitted to complete the tier they are enrolled in.


There’s also an exam to test technical know-how and understanding of plumbing codes. According to the Massachusetts State Board of Plumbers and Pipefitters, before you take the licensing exam you must have an apprentice license, 5 years of on-the-job training, 550 hours (110 per year) of classroom instruction in plumbing code and theory from an approved school, and work for a master plumber.

Approved school by the MA Board of State Examiners of Plumbers and Gas Fitters.
