It's not an apples to apples comparison. As a Flatiron grad myself I can tell you that most my classmates already had college degrees. They do have a program that serves as a substitute for college, but it's not clear that the main program has been filtered from the data.

That said, I thought Flatiron was an exceptional investment, much higher ROI on my salary than college, but also served a fundamentally different purpose and role in my education than college.
