Worked in a shop that sent a kid off to Barnett's, not certain why. Basically the kid learned everything they taught him well enough to get a certificate of some sort. Still came back without the sense God gave him and an inability to figure out the best way to fix something. But it gave him a leverage point for demanding better pay from the shop owner since there was no agreement to sending him which the owner had to pay. So it might get you better pay if you have one by establishing a base skill level.
