NDA is the only International Baccalaureate Diploma World School in northwest Ohio. We choose to be an IB school because the way people work and interact has changed significantly in the recent years. Thanks to the internet, knowledge is everywhere and we are globally connected.Inquiry and critical thinking skills are what will be most valuable to your daughter. IB is a college-level, self-driven, mentored program where the teacher coaches the student through her own inquiry.
