A dash under earnings or debt means the U.S. Department of Education has not published a figure for that program — it withholds any median computed from too few graduates, which covers about four of every five programs. It never means zero, and it says nothing about whether the program is any good. Where a figure is shown, the number of graduates behind it is shown with it.
Email me when these figures change
The U.S. Department of Education publishes new cost, debt and earnings figures once a year, and every number on this page changes at once. One email when that happens for Environmental Control Technologies/Technicians — nothing else, and nothing in between.
