Its staff are state employees, and it may use the federal paperwork or forms of its own. Apprenticeship.gov lists the Wisconsin State Apprenticeship Agency as the contact.

Either way, a registered program means paid work with a mentor, raises as you progress, classroom instruction and a credential recognized in every state. Search open spots in the Apprenticeship Job Finder.
