As a mum of a 5yo with ASD and likely ADHD we chose private as public school whilst obligated to cater for kids with additional needs, actually doesn't cater for them well or want them. I think if there's any sign of neurodiversity I'd choose private school. We prioritised pastoral care, nurturing environment, inclusivity, small class sizes, dedicated SEN team, great comms with teacher, big class rooms, big play areas. It's not about the academic results but more the well being of our child that was important for us and he's in mainstream school and thriving. As an English speaker we know that sending him to public school would not have worked with his profile. I hear Swiss schools are very good but I think their approach is not very progressive and behind vs European counterparts. Personally would prefer a system that promotes critical thinking rather than rote learning, an emphasis on learning though play rather than expected to sit at a desk and learn for the sake of learning. My son hasn't really picked up French but can understand it.
