Help choosing school for D

So am I understanding that she would get funding like a TA job and be on a track to get her masters and phd at the same school. 5 year program. But, that means she wouldn’t be able to work as a professor or clinical psychologiest? Her plan is ultimatly research on mood disorders and educating people on that (and perhaps effecting law), but she had assumed to pay for her phd she would have to work as a clinical psychologist and then after that as a prof. She does want the ability to prescribe. Man, so much more to learn about here.
