About the 248 CMR 11.00 Requirement

248 CMR 11.00 governs the continuing education requirements for Massachusetts licensed plumbers and gasfitters in the Commonwealth. It requires licensees to complete continuing education during each two year renewal cycle, the Board of State Examiners provide a course agenda for a new session each year.

  • Journeyman and Master Plumbers are required to attend one 6-hour course annually, totaling 12 hours of Board approved continuing education in the two year renewal period.
  • Journeyman, Master, and LP Gasfitters are required to attend one 3-hour course annually, totaling 6 hours of Board approved continuing education in the two year renewal period.

A certificate of completion is issued to the licensee as evidence of completing the required training and IAPMO submits licensee information to the Board office in compliance with 248 CMR 11.00
