Verdict
Reciprocity agreement
Mississippi is on South Carolina's reciprocity list, which puts this move on the streamlined track — on two conditions. Your Mississippi license must have been earned by examination, not grandfathered in, and be active and in good standing; where it is, South Carolina waives its journeyman exam and the requirements below are what it still insists on. South Carolina waives only the technical (Residential Plumbing) portion of its exam for an applicant who holds a residential plumbing license obtained BY EXAMINATION, current and in good standing, in North Carolina or Mississippi — the only two states with a residential-plumbing Exam Waiver Agreement (grandfathered or waived-in licensees do not qualify); every applicant, including waiver applicants, must still pass the South Carolina Business Management and Law exam, and all others must pass both the Residential Plumbing technical exam and the Business/Law exam. One caution: these agreements are directional and revocable.
