I have similar questions... Two offers I got mentioned TA/RA in exchange for tuition and stipend for the first 2 years, and the department will help students secure dissertation funding for the 3rd/4th year. However, no mention of actual amount yet... Another program mentioned 4 year fellowship, but still no mention of actual amount... I wonder whether all schools would provide financial aid info before April 15th?
congratulations and good luck with your next interview! Can i ask did you apply for the metrics track or the implementation track at UW? also, from the schools you did interview with, do you know approximately what is the admission rate for those invited to interview?
