I will tell you more about other job sites as we go along, but these are two of my favourites. Joyjobs scours the net for jobs and then creates links to the schools advertising for jobs. During the hiring "season" there are dozens of jobs per day but even now there are probably twenty or so during the day. These are jobs in administration and teaching and I have always had great success with this site.
I would say that TIE online is probably a little more "professional" in that schools have to pay a little more to advertise here so the jobs may be slightly different but it is the same concept. Not all international schools are the same so you have to be a bit wary of what schools you apply to. You can ask me what I think of a particular school or area whenever you like.
I will tell you about other job sites I like as this blog continues but these are two of the main ones. Others may want to add their favourites.
