I always felt student input should be a huge factor in teacher dismissals.

I felt my classmates were very fair with teachers. They didn't know the politics at the instition.

They didn't dislike a teacher because the course work was difficult.

They didn't like teachers who phoned their class in like an annoyance. They didn't like egotistical bullies which in my schools we all tenured teachers.

(I wouldn't mind seeing huge changes to tenure.)
