Verdict
Licensure by endorsement
North Carolina is not among the states Iowa names for an automatic exam waiver, so this move runs on the Iowa Plumbing and Mechanical Systems Board (Department of Inspections, Appeals, and Licensing)'s individual endorsement or equivalency review rather than a guarantee. Iowa waives its journeyperson plumber exam only for applicants who hold a South Dakota plumbing license obtained on the basis of written examination (its sole reciprocity agreement, approved May 2016); every other out-of-state plumber must pass the Iowa journeyperson exam. Bring your North Carolina license, proof that it is active and in good standing, and your apprenticeship and exam records — and get any discretionary exam or experience credit in writing before you rely on it.
