They nominated me for a university-wide scholarship, which might explain why I've received mine so early. The letter indicates that if I don't receive that scholarship, they will be providing a minimum funding commitment of $22,500/yr + tuition and fees. This covers 5 years of funding. They've listed some teaching requirements, but it's uncertain if what they've mentioned is part of the standard package or if they are requirements of the specific scholarship. Hope this helps!
