Massachusetts requires a journeyman plumber license for most plumbing work. The typical path starts with a 4-5 year apprenticeship program totaling 8,000-10,000 hours of on-the-job training combined with classroom instruction. The United Association (UA) Local 12 in Boston and other regional locals offer the most comprehensive training programs, though non-union apprenticeships are also available through contractors and technical schools. During apprenticeship, you'll earn progressively higher wages starting at 40-50% of journeyman scale in year one, reaching 80-90% by year four. After completing your apprenticeship, you must pass the Massachusetts state licensing exam to become a journeyman plumber. The exam covers state plumbing codes, safety regulations, and technical knowledge. Some municipalities like Boston have additional licensing requirements. Community colleges like North Shore and Bunker Hill offer pre-apprenticeship programs that can give you an edge. Steamfitters and pipefitters may pursue additional certifications in welding, HVAC systems, or industrial processes. Union apprenticeships typically provide better pay progression and job placement, but acceptance can be competitive requiring aptitude tests and interviews.

The $92,670 gap between 10th percentile ($47,830) and 90th percentile ($140,500) workers reflects significant earning potential based on several factors.
