Union apprenticeship sign-ups near Knoxville - 6 weeks in

The training centre near Knoxville opened applications for apprenticeships in electrical and welding trades. I am in Knoxville, in case local advice matters. The application needs a diploma or equivalent, a driver's licence and a short aptitude test. Did anyone go through it?

Visit the training centre in person if you can. Seeing the classrooms helped me decide.
