Your situation is very similar to mine. I also will be relocating to NJ (Jersey City area) from Australia and am an elemementary teacher who will be looking to get teaching work in the Jersey City area. Currently I teach 2nd grade in Australia in a great class at a wonderful school which unfortunately I will have to leave pretty soon

. I'm getting married to a US citizen and NJ resident in October and my fiance already has work in NY. We want to be somewhere in the Jersey City area for affordability and transport (I still have to learn to drive on the other side of the road). I"ll have the additional hurdle of having my degree recognised prior to finding work as well. I wouldn't mind doing teaching assiting or similar to get aquainted with a new system/country.
Have you had any luck in locating a job yet?
I did find a little bit of information on schools from Wikipedia by typing in Jersey City, and there's also the NJ Dept. of Education website (although I figure you may already know about that) at www.state.nj.us.education/ (broken link)
There are some agencies who deal with teachers for substitue work, such as
www.njhire.com and jobs appear to be advertised at
Find teaching jobs, school jobs, education jobs at SchoolSpring.com! There are some private schools in the area. It all depends on what you're looking for. Don't quote me on it because I won't say I know all the facts, but from what it appears, to teach in NY you need to pass knowledge-type tests whereas in NJ you don't.
Morristown and Montclair would be nice, but I understand about the commute. My future in-laws live in Central NJ and my fiance warns me I will find things a little bit different when we're in Jersey City.
All the best with your searching!
