There are definitely hard cutoffs at some schools with these kinds of guaranteed free tuition programs, and I suspect at all of them - they just don’t publicize the number for whatever reason. For the current cycle, I was told by a Colby rep that their “typical asset” threshold for free tuition under 200k income is $500k in family assets including home equity, and a St Olaf rep told me that theirs is $200k excluding home equity. No idea what Yale’s is, but I’d bet they have one. And you may not always be able to reverse engineer the answer through NPC, as St Olaf admitted to me that their NPC is not sophisticated enough to handle the permutations of their affordability thresholds.
