Apprenticeship openings for electricians and welders (Dallas)

I heard of an apprenticeship with paid on-the-job training for people changing careers. The application needs a diploma or equivalent, a driver's licence and a short aptitude test. What do you wish you had known?

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

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
