Hello Margaret, 

Thank you very much for your reply, and for helping Lola finding the right school for her. We had a meeting yesterday with the headmaster of her school, The Grange, and according to them, the best time for her to be absent from her school and not to miss too much, is either on her second semester of tenth grade,  September- December 2018, or during the Chilean summer break mid December thru March(12-15-18 thru 3-15-19). This second option would be less disruptive for school, since her school has the A levels system. Let me know if you need more info, and if you think it would be a good idea to set up a skype call.
