Since the mid 80s, I have been hiring employees from Community College machining, welding, and manufacturing programs. I hire kids who have just finished 2 year AA degrees, which, to me, has indicated a fair amount of discipline, and a sincere interest in metalworking.
I have probably hired 30 kids out of these programs over the years.
They are not ready to go machinists or welders, but they have the basics, have actually run machines, and can tell aluminum from steel, know what a millimeter is, can measure and are ready to train.
Even if you get a full scholarship, as several of the vets I have hired did, you still have to have a part time job to live while in school, so these people have all been more than just green high school kids- they have made a conscious choice to learn metalworking skills, then paid time and money to do so.
I get to know the instructors, and hire on their recommendations, and several have ended up working for me for 5 years or more.
Works for me.
