Based on your screenname and what I've read about Lower Austrian International School, it sounds like it could be a good fit for you. As you most likely know, the school integrates academics and athletic pursuits. They offer the International Baccalaureate programme which is used around the world. This curriculum is popular with expat parents because it allows an easier transition between countries, assuming both countries have a school teaching the IB curriculum. The LAIS website isn't particularly easy to find, so you might not have come across it yet. You can have a look over at this link: www.borglsp-stpoelten.ac.at/joomla3/index.php/l-a-i-s-section
