My oldest son decided to major in Computer Science. Hard worker, but doesn’t have the patience or willingness to sacrifice the time to actually go to school. He’s taken some CS courses (essentially 1 year of college), now working full-time at 50k doing programming. Wish he would finish - fear his growth potential will be limited.
At the very least have him look at certification courses. If he works in Microsoft technologies there are loads and loads of class called MCTS series. Your buy the book and study on your own then take the test. Books and tests for each level run about $250-$350. There are come classes you can attend also if that is your bag.
I am sure there are the same offerings in other technologies.
