What type of “top ranked” program are we talking about here? If parent is trying to get into MIT after a long educational hiatus, then, ok, maybe it’d be a bit difficult. But if they’re hoping to obtain an EE or CS degree (for example), these programs—in the states—are usually accredited and if their engineering program is not accredited, you shouldn’t even entertain the idea of entering that program.
There seems to be this constant myth that comes up when talking about higher education and that is a top ranking = better. Don’t get me wrong, a social science education from Yale or Brown will differ greatly then one at a state school but that is a given. Same goes for the select engineering programs or CS—think Cal, Georgia, MIT, etc.—but something like engineering is a program that has to follow strict course requirements so your end goal is practically the same no matter what your alma mater is.
