What the New Hampshire data shows for Plumbers

Becoming a licensed plumber in New Hampshire means clearing a defined set of hurdles: 4,000 training hours, a passing score on State Journeyman Plumber Exam, and 4 years of supervised work experience, plus a background history check once the applicant turns 18. New Hampshire regulators place this credential inside their licensing framework, which classifies the training track as "Apprenticeship Program".

The initial price tag is $30, and renewal costs $30 every 1 years. Renewal isn't the end of the cost: 8 hours of continuing education are due every 1-year cycle, a recurring time commitment worth planning for.

Reciprocity for this profession works like this: Journeyman licenses rarely reciprocal — check state board.
