Well, since nobody else has answered, I'll chime in. But I am, by no means, a Waldorf expert. I have 2 kids who go to a K-12 Waldorf school (1st and 3rd grade) and another who will likely start Kinder in a year. I started at Waldorf very naive of all the Waldorf controversies and concerns. The school had come highly recommended by several of my colleagues who have kids there, so I toured the school and went for it. I knew there were concerns about the delayed emphasis on academics in the early years meaning that some kids might go longer before their learning disorder was discovered, and also knew that it can be hard for kids to transition into regular schools in the early years as they will be behind their peers, but I was willing to accept those risks. Son after my boys started there 2 years ago, I because a little leery of some of the things I was seeing. I didn't fit in well with the other parents and I did not take easily to the emphasis on "magical thinking". I've always been a practical, scientifically minded person and it goes against my nature to encourage belief in fairies, gnomes, and even God for that matter. Then I began reading up on some of the negative Waldorf information out there; there is a lot of it if you look around. And I basically freaked myself out. I was to the point of thinking I would pull them out of Waldorf, but I decided I shouldn't base that decision on what other people had experienced at other Waldorfs. So I made myself stop reading negative things on the internet and just decided to watch my kids and their interactions with the school. Two years later and we are still going to our Waldorf. It's not a perfect school and certainly not the perfect fit for our family; but I think based on the alternatives, it's as good as I'm likely to find without home schooling (and I would be terrible at homeschooling).
I could probably write a hundred things more, but I will just try to give a few examples (good and bad) of where my kids and their cohorts are at:
-my 3rd grader: we were in the car last year with 3 of his non-Waldorf friends. One of them mentioned the eruption of Vesuvius (I think they were talking about volcanoes or something) happened in 70AD. My son had no idea of this event, but when I asked how many years ago that was, he came up with the answer in seconds flat, whereas his friends were still slowly doing the math in their heads.
-same 3rd grader is not at the same reading level as his cousin who is 5 mo older and a grade higher, but he is close.
-my 1st grader (will be entering 1st grade next mo), still doesn't know his letters. For the most part not a big deal, but he sometimes gets embarrassed about it when hanging out with non Waldorf kids.
-my 1st grader had a friend who changed from Waldorf to public school last year, when she entered the 1st grade. I ran into her mom recently and she said they spent the whole year playing catch up because she was so behind (this was not unexpected).
-my 1st grader's cousin, who is a similar age, steals her parents' ipads and locks herself in the closet all afternoon to play on it. When I hear stories like that I feel smug, because that is a non-issue for my kids. (Of course, I never express my smugness to anyone).
-I am very anti-homework, and as of yet, there has been no homework for my kids, but all of their non-Waldorf friends have homework, including the Kinders.
-the after-school program at our Waldorf is phenomenal. I compare it to the public school after-care program that my eldest went to when he was in public Kinder. They would put movies in the VCR and let them watch, every single day!
Anyhow, it doesn't matter so much what my experience has been because it is so dependent on the individual school, and within that school, dependent on the individual teacher. I would encourage you to tour the school more than once, and sit in on some classes at different age groups. Talk to parents of kids there and kids who have graduated, to see how they fared when entering the real world. And only give weight to negative reviews about your specific school, not about Waldorf in general.
