For undergrad:
English, humanities, journalism/media, business, polysci, most of the fine/performing arts advantage Iowa.
Mathematics, STEM, many of the hard sciences, ag sciences, graphic design, interior design advantage ISU.
Lots of programs probably pretty even between the two. My daughter will be starting at ISU this coming fall in elementary ed, and we absolutely loved the faculty advisor we met with on our campus visit. Those programs might be equal but ISU completely won us over.
What I’ve seen, as of late, is Iowa and ISU are pretty comparable in the business degrees. ISU has been focusing on Masters degrees and have been really driving to improve in them.
