I can't think of any reason it wouldn't be taxed as ordinary income also subject to self employment taxes. They can do things like S Corps and offset the income with some expenses but it would be munimal. Even if they ran it through as scholarship money which I highly doubt is the case that would still be taxed at ordinary rates since they already have a full ride. Just wouldn't have self employment tax.
I'd be more curious in seeing what ABM's cut is
