I am a US citizen thinking of relocating to Istanbul in January 2021. I have a 17-year-old son with Down Syndrome. Thank God, he is a high functioning teenager: He plays football, basketball, swims, reads English, writes, does some math etc..His speech is very good. His main language is English, but he speaks some Arabic. No behavioral problem thank God. Im looking for a school for him in Istanbul in English, preferably an inclusion school with in-classroom or special support. Does anyone have experience in this area? Do you recommend any schools?
