Things are changing from last year to this year at Arizona State. Last year, everyone got $15,000 (in state) and 25,000 (out of state). This year it is different. The minimum is I believe $11,000 (in state) and $16,000 (OOS) and that can be increased based on "need" and "academics".
In other words, they are not going to give a fixed amount, but try to vary the amount based on the individuals needs and ability to attract the student. Hence, first get admitted and then you can get a better idea from ASU
