Upcoming dismissal as supervisor no longer wants to supervise me - should I just withdraw? Basically my PI dropped this on me last week and said that my work is not up to PhD standards. It's pretty frustrating because seemed like I was on track to graduate this year. That said, my PI has brought this up before - since then I had shown I was improving and had met his standards, or at least I thought so.
My school's official policy for my situation is that

A Student will be withdrawn from the University, if he or she obtains two unsatisfactory Graduate Student Research Progress Tracking Reports and the academic unit in which the student is registered recommends that he or she be withdrawn
The Student’s transcript will thereafter indicate that the student was withdrawn from the University.

Regardless I won't be able to work with him anymore. I've been looking for someone to finish under, but it is looking a bit hopeless right now. If I cannot find someone else to work under, should I just request to withdraw? If voluntarily withdrawing is an option, it seems better than being dismissed/kicked out.
In the future (specifically in interviews) I'd rather say &quot;It wasn't working out for me so I withdrew&quot; than &quot;I was kicked out&quot; to people.
I'm meeting with my department chair next week, but hopefully someone can give me an opinion based on their own experiences.
Does your university have a mentoring system? I think you need to sit down with a mediator and the PI to try and work out a solution where you can continue either under the PI's guidance or someone else. If you do not have a mentor, then you should talk to another Professor who you think will be sympathetic and be able to guide you. Something is terribly wrong if you are being kicked out and it is a surprise. You need to set-up a meeting and negotiate a solution, a meeting with the department chair sounds a bit abrupt, unless they can help find a solution somehow.

I cannot give an answer as to whether you should withdraw. But if you were under the impression you can graduate this year, then withdrawing does not seem necessary. You will have wasted at least three years (presumably).
