Finding an apprenticeship in Maine

Maine runs Registered Apprenticeship through its own State Apprenticeship Agency, recognized by the U.S. Department of Labor to register and oversee programs there. Its staff are state employees, and it may use the federal paperwork or forms of its own. Apprenticeship.gov lists the Maine State Apprenticeship Agency as the contact.

Either way, a registered program means paid work with a mentor, raises as you progress, classroom instruction and a credential recognized in every state. Search open spots in the Apprenticeship Job Finder.

Across the country. Some technicians train through an apprenticeship, which usually lasts several years. Each year mixes paid on-the-job training with some classroom work on safety, blueprint reading, and heating and cooling systems.
