I don’t think the US News graduate school rank is all that relevant, but a little bit, for CS. I would for certain look at Madison and U of Minnesota carefully if he is OK at a big public program. GaTech OOS price is also pretty good, but no merit available there. GaTech is a very strong CS/math school and smaller overall than the big midwestern Flagships. I would also look at Purdue U, they offer OOS merit as well, and UW Seattle offers OOS merit. UW could be quite difficult to get direct admit to CS. Purdue works out to be a little less expensive than GaTech if you son wins the OOS merit at Purdue. Purdue offers data science, cybersecurity focus ,and strong CS degree.
