At Lambda, students pay nothing upfront. But they are required to pay 17 percent of their salary to Lambda for two years if they get a job that pays more than $50,000. (Lambda says 83 percent of its students get a job with a median salary of $70,000 within six months of graduating.) If they don’t get a job, or their salary is lower, they pay nothing. Payments are capped at $30,000, so a highly paid student isn’t penalized for success, and if a student loses a job, the payments pause.
