The University of Wyoming is the only public school to be named the most expensive school in a state. That's not because it's expensive — it's easily the least expensive school on the list — but because it's the only public or private not-for-profit school in the state.

Methodology: GOBankingRates identified the most expensive public four-year institution based on in-state tuition and the most expensive private not-for-profit four-year institution based on tuition for the 2016-2017 academic year, using data from the National Center for Education Statistics. We chose the most expensive school for each state, then went to each school's individual website to source tuition costs for the 2017-2018 or 2018-2019 academic year, whichever was listed by the school.
