First, aspiring plumbers begin as journeymen-in-training.

In the majority of cases, they are enrolled in a technical program.

When they finish this, then they move up to the journeyman level and finally to master.

Unfortunately, Maine does not have reciprocity agreements with specific states, but the state will consider license reciprocity in accordance with the licensing standards and experiential requirements unique to the applicant’s state of origin.

This means that under the laws and rules of the Plumbers’ Examining Board if the state in which an applicant received the license holds at least equal standards and requirements as Maine, he/she will be granted reciprocity.
