Our first overseas experience, which we loved, was in El Salvador. We moved to Chile and found ourselves in a great country but a hellhole of a school. So my first piece of advice is that these are all VERY different locations, so it's impossible to generalise about You may need to be more specific about schools you are interested in. I cannot emphasise this too much as many inexperienced Brits make the mistake of lumping all the Latin American countries together. A couple of weeks before moving to Santiago my debit card was cloned in Guatemala and a money stolen from my account. When I contacted my Bank (Barclays International, would you believe?) they insisted that I report the theft to my 'local' police station and obtain a crime investigation number. When I pointed out that the theft had occurred in Guatemala and I lived in Chile the dozy doxy on the other end of the costly international telephone call said 'Well, it's all the same place, innit?' As the regulars on here know, I like Search Associates. TIE strikes me as a more American style medium, though I once found an (American school) job through them, in the hellhole school, as it happens.
