I went to the open house today: Spacious new location! My child attended middle school at CoIS. He enjoyed fabulous teachers from all over the world. The academics were personalized, accelerated, creative and rigorous--and he can speak Mandarin and French. The cultural activities, field trips and guest speakers were such a surprise: He met consulates, professors and professionals from all over the world. The sports were next-level. For example, the students regularly attended rock climbing at a rock climbing gym and archery at an archery range! One of my favorite features was the bully-free environment where teachers had the luxury of teaching without interruption. -- tree oh tree, nine one ate, five won ate too.
