I'd have to say whatever the waldorf schools are doing is working. My father-in-law's neighbor is an education PhD and her son has been in waldorf schools from the start. He is the most intelligent, wise, and confident kid I have possibly ever met, and he takes care of a wide range of animals at home (horses, chickens, alpaca, pig). He always seems fulfilled and is always excited to talk about what he is learning in school.
His mom who was previously writing and editing textbooks took a job at a public school in a lower income area of the county. She couldn't stay for even a year as she was so upset and dissapointed with the methodology they were using, heavily relying on screens and allowing kids to get away with everything.
I know that I will definitely do everything I can if I have children to get them into the same school.
