Local 4 offers apprenticeships in plumbing, pipefitting, and HVAC tech. Apprenticeships take five years to complete through classroom and shop training at night, and on the job training during the day. In addition to plumbing, pipefitting, and HVAC instruction, all apprentices receive training in welding.

In addition to plumbing, pipefitting, and HVAC instruction, all apprentices are required to attend training in welding one night a week.
We are currently accepting applications for the 2027 opening. Applications are ONLY accepted the second Wednesday of each month from 9 a.m. to 3 p.m. You must come in person to apply. You do not need to bring anything at that time. Applications will be held on file until late spring/early summer 2027, when all applicants will then be scheduled to take two assessment tests. Interviews, for those who make it that far in the process, will be held in November 2027 with classes beginning January 2028 for those accepted into the program.
For those applicants who already tested for the 2026 opening, letters were mailed the week of August 10th. If you don’t receive your letter in the mail by September 8, call the hall at (508) 835-1150, ext. 1.
