Alabama to Wisconsin: master plumber license reciprocity
Wisconsin has no reciprocity agreement with Alabama. Your Alabama experience counts toward eligibility, but you must pass the Wisconsin exam.

Out-of-state master plumber (no reciprocity; exam required, journeyman experience credited toward eligibility)
Nothing is waived, but your documented out-of-state hours count toward eligibility to sit the exam.
DSPS publishes no plumbing reciprocity partners and no exam waiver for out-of-state master plumbers, so a master licensed in another state applies through LicensE under the comity (out-of-state) method and must pass the Wisconsin two-part master plumber examination (open book, 70% on each part to pass). DSPS lists two comity routes to that exam. The first is a five-year out-of-state plumbing apprenticeship with at least 576 hours of related instruction plus at least 1,000 hours per year for three years as a licensed journeyman plumber. The second is a current plumbing license and at least 8 years of plumbing experience, including 1,000 hours per year for at least three years under the laws of another state or a city, town or village, documented with a state license verification and the Trades Experience Form (Form 8168). Wisconsin has no separate law or business exam for individual plumbers.
A graduate of an accredited engineering program in civil or mechanical engineering, or another approved plumbing-related engineering curriculum, may also take the exam (SPS 305.91). Restricted master is a separate DSPS credential. The license is issued for four years and costs $500; the initial fee is prorated when the first term is shorter.

Statewide license
Issued by Wisconsin Department of Safety and Professional Services (DSPS)
Wisconsin issues a statewide, person-held Master Plumber license through DSPS under Wis. Stat. ch. 145; no person may work at plumbing without a DSPS license (Wis. Stat. 145.06), and under SPS 305.91 a master plumber responsible for an installation must use appropriately credentialed persons to do the work. A new applicant applies in the LicensE portal with the Trades Experience Form (Form 8168) or an engineering degree, is made eligible to test, and must pass the DSPS master plumber examination, a two-part, open-book exam (70% on each part to pass) on Wis. Stat. ch. 145, SPS 305 and the SPS 381-387 plumbing code. DSPS's plumber pages name no reciprocity states.
