What the Maryland data shows for Plumbers

Maryland's path to plumber licensure runs through 6,649 hours of approved instruction, 4 years of supervised work experience, and a passing score on State Journeyman Plumber Exam, plus a criminal history screening before applicants younger than 18 can be licensed. Maryland folds the credential into its broader occupational licensing statute, which classifies the training track as "Apprenticeship Program".

The initial price tag is $209, and renewal costs $176 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.

On reciprocity, plumbers should know: Journeyman licenses rarely reciprocal — check state board.
