I have a friend who has just learned that she's unable to do a teacher exchange through her school board.  In Australia and New Zealand, the school term begins in January and her superintendent was unwilling to allow this exchange.  She's now looking for other alternatives so that she can still experience the opportunity to teach overseas.  Ideally, she's looking for the chance to go to somewhere English speaking - Australia/NZ/UK.  We've been searching on the net, but of course, there's a multitude of websites citing opportunities.  Does anyone know of a reputable website, association or recruitment agency through which she could continue her search?
