How do I voice my opinion that the teaching of students is being neglected? I'm in a Phd program right now and it seems there are some unethical practices going on in my department. Examples include: testing over irrelevant material or material that was not really covered, not grading/giving feedback on homework, instructors breaking college and department policy for convenience, dishonest course description and listed prerequisites.
When I got my masters in a different discipline at another institution, I felt everything was so well put together and my instructors really cared about the class and the students. I have considered leaving with a masters in stats since I feel slimy for participating as a TA in what I mentioned above, but I would like to reach out. Does anyone care? Would anyone listen? Who should I reach out to? How should I phrase my concerns?
I can include more details if that would help.

EDIT
I wanted to give more details:
I'm in a Phd stats program right now and I have a masters in math (I was all but dissertation)
I TA for a masters level core class. The instructor doesn't grade, lecture or make notes for the class (they are reusing the video-lectures and notes of another instructor from previous semesters). As far as I am aware, the instructor just pulls questions from a bank of questions for tests/homework. When I learned the material, I took a two semester sequence to cover everything and we still didn't cover all the material this class does. Every semester, masters students spend more than 1000 USD on the course and have to drop due to lack of background even though they work hard. Last semester about 25 out of 80 students dropped. The only prerequisite for the course is calc III.
For another course, the boss (instructor) of another TA in my cohort tried to make the TA create the assignments and tests which is against department policy.
In my case, I have had several instructors whose exams don't reflect the material covered in the homework and I feel that I could have not studied and done just as well (bad) because the exam questions end up being some difficult honors calc II question instead of using the material we cover in class. In fact, one instructor got stuck for a few minutes when giving us the solution to a problem that no one was able to solve on an exam. A subgroup of my cohort is unable to attend office hours for a required class due to having another required class and the instructor was unable to accommodate them due to &quot;being too busy with research&quot;.
In summary, I feel that the department is trying to make money off of master students and is more focused on research than being good teachers.
Maybe this is normal and didn't know since my last institution was really good. Just let me know if it is. Thanks for your time.
The fact is that institutional norms and expectations regarding teaching vs research for faculty vary widely. At my current institution, teaching is very important. At my previous institution, no one really cared. Basically, I would not voice this opinion in any strong way unless you want to make your life difficult. It would only work if the faculty member you are working for is disliked and the person you complain to is firmly on your side.
I did have a similar situation as this in my PhD institution and &quot;voiced my concerns&quot; in a very tactful way. I argued that the course was extra challenging because it was a new advanced level course and had not been given enough resources. (Note that I was careful to say nothing about the effort or quality of the instructor.) The department was able to pay me extra as a TA to take over some of the instructor’s responsibilities. But the instructor was someone who got on the other faculty’s nerves, and my advisor was the associate dean for academics.
