Moving to Missouri as a master electrician: every state's rule

Relationship between the state and local licenses. RSMo 324.925.1: political subdivisions may establish their own local electrical contractor license but shall recognize a statewide license in lieu of it, and may not require a statewide licensee to pass any examination or proficiency assessment; a jurisdiction that refuses can have its local sales tax withheld. Subdivisions may still require business licenses and permits, inspect work, and license electricians and contractors who lack the statewide license based on experience plus a nationally accredited exam (324.925.3). The statewide license covers only the contractor/qualifier, not employees.

Springfield. Building Development Services certifies Master Electrical craftsmen: 4 years as a certified journeyman in the trade or 10 years of satisfactory experience, notarized employer experience forms, approval by the Building and Trades Board (first Thursday monthly), then the ICC master exam through Pearson VUE (about $125) with a 75% minimum. Reciprocity from another jurisdiction is available by submitting a score of at least 75% on the identical exam from Prometric, Experior, Block or ICC plus the experience forms; copies of licenses held in other states must be attached. Initial master certificate $50 (covers the rest of the year), renewal $50 annually. A licensed master must generally be listed on electrical permits.

City of St. Louis. The Committee of Electrical Examiners examines applicants for electrical certificates and licenses by written and oral exam covering practical installations, theory and the St. Louis Electrical Code; classes, fees and reciprocity are not published on its page.

St. Louis County and Kansas City. Both operate electrical contractor and master licensing programs, but their websites blocked automated retrieval during verification; requirements are not recorded here.

Out-of-state masters. The statewide license is the practical route for a master electrician moving to Missouri who wants to contract anywhere in the state: one application to OSEC, acceptance of a previously passed national master/contractor exam, and no local exams afterwards. Someone who only needs to work in one city can instead apply to that city, which will generally accept the same national exam scores.
