What these numbers are
Earnings: graduates of 2017-18 and 2018-19, earnings measured in 2022 and 2023, in 2024 dollars. Only programs with at least 30 graduates in the earnings cohort are listed, and a multi-state system whose figure pools campuses in several states is left out of state lists. Median earnings of graduates who received federal student aid, worked, and were not enrolled in school; debt is the median federal loans borrowed at this college by graduates who borrowed (Direct Subsidized, Unsubsidized and Grad PLUS; not Parent PLUS, private loans or interest). Programs with too few graduates are suppressed by the Department of Education. Federal program group: Plumbing and Related Water Supply Services. Earnings reflect who enrolls and where graduates work as well as the program itself.
