Why these exist: These are indeed waivers - generally speaking, they're used for three things: 1. To prevent the state from paying the state to educate a graduate student by waiving tuition that would be paid from a stipend, etc. 2. To acknowledge that graduate students must remain enrolled in a program for several years while working on research, but aren't taking classes and probably shouldn't be paying tuition. reply 3. To partially adjust graduate students who have no chance of getting in-state tuition (i.e. foreign students) to the in-state rate so that it's possible to recruit grad students.
