Class Central has identified six different tiers that MOOC providers monetize on. To be clear not all MOOC providers monetize their courses at all six tiers. Even those platforms that do have offerings that fit our model don’t necessarily follow it for all of their courses. Still, we do think it is helpful to talk in general about a six-tiered monetization model. To illustrate, we will look at the example of the iMBA, produced by University of Illinois at Urbana–Champaign and offered on the Coursera platform.
