I've taught several classes at U of Phoenix in the past four+ years, and I'd taught at other universities prior to Phoenix (and sometimes concurrently.) In order to qualify to teach at Phoenix, I had to first go through training, which took several weeks, and was unpaid. Then I had to teach my first class under a mentor - senior, experienced faculty, who guided me every step of the way. That took seven more weeks. Only then was I able to run my own classes. I'd never had this level of training to teach at any other college. In fact, no other college I've adjuncted at gave me any training at all.
I feel no pressure whatsoever to pass students, and have, in fact, failed several. I have experienced no repercussions for doing so. I also find that this university is much more supportive than others I've taught at re: supporting me when I report plagiarism, which I find refreshing.
I find that, compared to other similar level unis/colleges where I've taught, U of Phoenix students have better writing skills, which surprised me. That was not what I expected. There have been the occasional students where I've wondered how they've reached my level of classes, based on their writing skills, but they are the exception, rather than the rule. I do teach more advanced classes, so I'm sure that helps, but compared to similar level classes at other colleges where I've taught, I've found that Phoenix students are better writers.
The U of Phoenix has a large and comprehensive online library, with actual human librarians available to help both faculty and students. They also offer tutoring and other support in writing and math, which includes the ability to speak, live, to a human being.
The university offers extensive faculty support - more than I've had when I've taught at places like the SUNYs. There are forums where faculty can discuss issues with other faculty, and also get answers from administration. There are ways to reach IT and senior level faculty to get a quick response on an issue.
All in all, I've enjoyed teaching at this university. I would not recommend that anyone I know go there, due to its poor reputation with employers and other schools, but I like working with the students there.
