To identify the most expensive college in every state, 24/7 Wall St. ranked schools based on net price in the 2018-19 school year for students who received financial aid. Net price — for full-time, first-time degree-seeking undergraduates who were awarded financial aid — includes tuition and fees, books and supplies, and on-campus room and board less any grant, scholarship, or aid from federal, state, local governmental or institutional sources. Data came from the National Center for Education Statistics. Data on applicants and admissions used to calculate acceptance rates also came from the NCES and are for the 2019-20 school year. Undergraduate enrollment for the 2018-19 school year came from the NCES. Only colleges that predominantly grant bachelor’s degrees were considered.
