"Graduates earn" is the median two years after completing, from the U.S. Department of Education's College Scorecard, released 2026-06-10; the number in brackets is how many graduates it covers. A dash means the Department has not published a figure — it withholds any median computed from too few graduates — and never that the figure is zero. "The occupation pays" is the state median for the occupation the program leads to, from the BLS Occupational Employment and Wage Statistics survey, and describes everyone in that job rather than graduates of this school.
