I contacted sons agent who did his contract and a family friend forever.
He is a man of few words. But his answer was what I expected.
It's ALL negotiable and not free money.
I believe this is the best resource (and ground truth) regarding continuing education:

Things have changed over the years. The current program is CEP (contracts signed after 5/1/2017):
@keewart posted:Thank you @ABSORBER, that is exactly what I was referring to. Son signed his contract after the draft in 2017.
What isn't included is the "front page" stating the money parts: tuition, living allowance and when the living allowance must commence.
From what I can read it seems to tie living allowance with attendance of classes--since you have to submit within 90 days of the date of the last class. It further states "that reimbursements under Living Allowance are only available for those classes attended within 10 years of the date that the participant signed his first Minor League Uniform Player Contract."
I do know a few folks who have signed contracts and only know what I have heard from them (as far as money is concerned). One draftee (HS) received a package that equated to the 4-year cost of attendance to the out-of-state university to which he was committed. Based on this info I would certainly expect to negotiate something similar if I was the parent of a HS player. Of course a college junior should negotiate for his last year of school but it seems to me a college graduate could perhaps negotiate some $$ as well (especially if he had remaining years of eligibility and had committed as a grad transfer) but currently don't know any draftees in this category. These players of course are up in years (== less value to team) but that doesn't mean they aren't giving up a potential grad degree when drafted.
