No. Steamfitters do not require a four-year college degree. The standard credential is a journeyman license earned through a paid apprenticeship registered with the U.S. Department of Labor at https://www.apprenticeship.gov/. Some workers complete a 1- or 2-year certificate at a community or trade college before applying — but the journeyman license is what employers actually require.
Steamfitter apprentices typically start at $53,180 per year (10th percentile) and progress upward each year of the apprenticeship. By year 4, pay usually reaches the 50th percentile around $69,782. All training is paid — apprentices are W-2 employees of contractors or unions, not students paying tuition.
Common steamfitter certifications include: State steamfitter/pipefitter license; Welding certifications (AWS/ASME); OSHA 10/30-Hour; Backflow prevention certification. Most states also require a journeyman license; some have a separate master license for independent work.
