Pros: salary/benefits good, good continuing education
Cons: individual schools can be worse than you ever imagined; largely data-driven culture
Some schools are excellent, some are your worst nightmare!
It depends largely on where they are,not the fancy titles they might give them. It may be unfair, but schools with a mix of middle class/affluent parents have many more resources and good discipline. Poorer urban schools can be an absolute free-for-all- even with good leadership and GREAT teachers, who are usually desperate to get out. I've seen the very best teachers unable to teach because students with severely disruptive behavior get away with anything. Sadly, teachers get the blame for scores even in those awful schools.Parent accountability/participation is non-existent.
The suspension rate won't tell you anything, because they hide the numbers, or cap it at a certain point. Best to do an impromptu visit to see if it is chaotic or running smoothly.
If you think of it as a "mission trip," you might survive, but you will give your whole life to it. If you think you'll be able to stay for a career, think again, or find one of the good ones and never leave if you can help it.
