A few children from our school have gone off to waldorf high schools (it involves moving away or boarding there, since none are close); the vast majority have gone to public high school or tradition private (Catholic or academic independent). I can speak authoritatively about my ninth grader (but that's an anecdote again); she's found high school easy after waldorf school. I am unaware of students who were completely unprepared for high school coming out of our school, but I certainly wouldn't say that everybody finds high school easy. Children with trouble doing assignments or working carefully at waldorf probably continue to have similar problems in high school.
I am trying to develop a database of admission testing history for our school, which I believe is in the school's interest, rather than trying to track the success of its graduates in follow-on education (which is much harder to do, and involves many more complicating factors).
