I think that each school should specialize in a few topics. Early grades can teach things like plants and medicines to identify and use, manners, creativity, productivity, and other. But middle school on should have more specific things to teach like specializing in health, fitness and sports, or technology and programming, music, herboligy, anything that kids would be more interested in focusing on. Each school having different topics. Teens learn better when they're interested. Children develop better under calmer environments that peak curiosity, allowing them to learn more simple but still important things like generosity and compassion, not trash-talking and bullying. But older kids can handle things like rough activities, coding or learning nurse work to help identify diseases or injuries. But all schools should still have atleast minor classes for things like Geography and math and such.
