BOC Score, tuition, graduation rate, and median graduate earnings from
federal IPEDS and U.S. Dept. of Education College Scorecard data. Earnings
are reported across all programs at the school (all majors), not a single
trade. Distance is measured from the main population center in Delaware.
Schools closest to the main population center in Delaware are gathered first, then ranked by BOC Score; distance from the main population center in Delaware is shown for reference.
The BOC Score is an independent measure of school outcomes (graduation,
earnings, net price, retention) expressed as a 0–100 percentile within
each school's peer group; higher is better and advertising never affects it.
