What the Louisiana data shows for Plumbers

A criminal history background check is also part of the application. Applicants must be at least 18 years old. The regulation sits under Louisiana's professional licensing framework, which classifies the training track as "Apprenticeship Program".

Budget $227 to get started, plus $191 at each renewal on a 1-year cycle. Maintaining the license requires 8 hours of continuing education per 1-year cycle, an ongoing cost applicants often underestimate when budgeting the career.
