>>I would think that it depends on if they were told in advance that they would have to volunteer 75 hours. If not, I think it is questionable as to it’s legality.
The contract you speak of is to provide an education in a discpline for a set price. You are also told about the books, materials and, if applicable, other expenses you can expect beyobd that. <<
You may have something there, but chances are good the admissions and registration documents allowed for such a change.
Trust me, I worked in Higher Ed for 20+ years and the contracts always favor the institution.
And, for the OP, the point is that whether or not the contract calls for such a commitment, it has nothing to do with “rights” and everything to do with “contract law.”
I agree. Especially if it was spelled out clearly within the contract. If it wasn't speleed out clearly I think they may still have a case against it.
