Again LongAce you miss the point. You have a student that tells you that he's not going to do his in-classroom assignment and then he tells you to go f*ck yourself! What are you going to do? You can't throw him out of your classroom because he's labeled as behaviorally disabled. So what do you do? I guarantee you that you wouldn't last a week.
But at least where I live, it doesn't work that way.
A lot of people here keep bringing up the point of controlling 30+ children. Realistically, it is more like 20+, and even that is only in elementary schools. In middle and high school that's really not an issue for the most part. If you choose to teach special ed that's your problem, a run of the mill teacher doesn't have to deal with that.
And if a student tells you to go f*ck yourself? Well, either fill out a discipline slip or ignore it. Students call each other far worse than they call their teachers anyway.
Where I live (a wealthy NJ district), teachers start at $41000 and get tenured in 3 years, which is absolutely ridiculous. At least, for most teachers anyway. Over the past 3 years of high school, we've had an onslaught of new teachers in history and english, but nothing in math/science. IMO they should lower history and english salaries $5k, lower gym teachers and electives $10k, and increase math and science teachers $5k. The principal makes a lot of money (6 figures), but that really doesn't matter, even if you cut his salary in half, the $50k or so distributed among 200 faculty in the school building really doesn't do much.
As for teachers themselves, most of them are garbage. That really is the truth, even in a strict hiring district like mine. There isn't enough quality teachers around to raise the standards, and having such a large scale evalutation process costs a lot of money.
Bottom Line: From my experience the prescense and quality of a teacher is really irrelevant. If a student is motivated and/or bright he/she will do great regardless, and if they're not having even a great teacher is unlikely to help.
And to the OP: Most of my teachers live in PA. You might want to consider living there for cheaper taxes and whatnot, if you school is near the border.
