Its a pretty wide spread depending what state.
North Carolina teachers start around $37k, averaging out later to $46k. Some counties are higher, some lower.
The pension plans are problematic, because many of them are under funded. For an older teacher about to retire this might not be an issue, but if you're 30 this seems like a much less certain deal.
Teachers are rarely compensated on an hourly basis, and when they are it probably doesn't count half of their hours.
Would your attorney charge you (in 5 minute increments) for a call at 7pm? You bet they would! But a call with a parent at 7pm nets a teacher nothing. Nor does preparation in the evening. Many teachers have exceedingly low classroom budgets as well, and are often forced to purchase supplies out of pocket.
The High School theatre teacher who is working on a play with students until 11pm every night for weeks and weekends isn't compensated on an hourly basis; or given overtime. Its just part of the gig. And that sucks.
I wouldn't mind being a teacher some day, as I love teaching; but unless I hit the startup lottery there's no way i can accept that level of compensation given my background, experience and skills. And even then, in a state like North Carolina that is more about rules than education, I can't see myself being able to last 3 days in that environment.
