Illinois registered apprenticeships
Illinois is an Office of Apprenticeship (OA) state; registered apprenticeships flow through U.S. DOL Region 5 rather than a State Apprenticeship Agency. IDPH licenses plumbers statewide under the Illinois Plumbing License Law (225 ILCS 320). Electrician and HVAC licensing are municipal: Chicago, Cook County, and other cities/counties set their own credentials, exams, and fees. Verify local requirements with the municipality where work is performed.
