@JizzelEtBass @KatyElphinstone it doesn’t even seem logical. It assumes that every child will have equal opportunity and means to be identified. No mistakes made, no parents without the means, no one with views that would prejudice them against proper evaluation (especially if the child’s parent, teacher, or doctor), no children that live their early life in a country where the situation is different, no gaps in understanding because the child is raised by people with a different culture, no doctors without sufficient education on autism, and on and on and on… any number of things could result in a delayed diagnosis.
