With high School players if you get drafted and the pay for your school upfront, are they allowed to go to College during the off-season?
Technically, yes, you can go to school in the offseason.
However, there are "fall instructs" at the spring training facility in the fall. Spring training starts in February and then games until into September. So, there is no real good time to go to school in the off season, unless you start late in September (most colleges start in August, so you could be several weeks behind). Online classes could be an option now. A serious injury that takes you away from baseball for an extended time may allow you to take classes.
But, as we know it, the MLB's scholarship program is a 'tuition reimbursement program'. YOU pay for college classes, room, and board upfront, and then submit your grades and expenses to get reimbursed. AND, the reimbursement is taxed (ie: you don't get your full amount refunded).
I understand that now in the contracts, it allows for x semesters, rather than just a total dollar amount. So if you are drafted as a junior, you would have 2 semesters. You would need to think twice about taking just 1-2 classes rather than a full semester.
Most players don't utilize the program, but glad to say KEEWARTSON GOT HIS DIPLOMA LAST WEEK!!! Online classes during Covid helped!
