When my son was going through the process, the best piece of advice that we got was to not accept a lump sum scholarship amount. To get the amount in a percentage form for the specific reason stated here. If tuition goes up, the percentage of money will still be the same percentage, thus, an incremental increase. We also made sure that the percentage wasn't just for tuition, with the remainder of board and meals to be our full responsibility. It was a percentage of the entire cost of attendance - tuition, meals and board.
