What the Missouri data shows for Plumbers

Missouri's path to plumber licensure runs through 5,351 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. Missouri folds the credential into its broader occupational licensing statute, which classifies the training track as "Apprenticeship Program".

Budget $121 to get started, plus $104 at each renewal on a 1-year cycle. 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.

For plumbers, the reciprocity picture is: Journeyman licenses rarely reciprocal — check state board.
