The fundamental difference between a Sudbury school and any other type of school is the student's level of responsibility. In a Sudbury school the students are solely responsible for their education, their learning methods, their evaluation and their environment.

In a public school, the state takes responsibility for most aspects of a student's education including curriculum and evaluation. The student is left with little responsibility except to learn what is taught, how it is taught, in the environment in which it is taught and then to reiterate it back at evaluation time.

In a non-Sudbury private school, the school administrators take a larger role in determining a student's curriculum than in a public school. In some private schools, the school takes responsibility for evaluation, while in others the school administers the state tests. In most private schools, as with public schools, a student has personal responsibility only for learning what someone else determines is important to learn, at a time they think it is important to learn it, in a way someone else has determined it should be taught, in an environment designed by someone else, and they must do this well enough to pass the evaluations written and graded by someone else.

I came to Sudbury Valley the first summer we were open. I was seven. I was really surprised when I saw the school. The picture I had before I came was nothing like what it turned out to be! I had imagined it to be a place with rooms that had labels according to what you did inside the rooms a room that said "Science," and a room that said "Reading," and I don't know what else. My picture didn't look like the public school I went to, but it also didn't look like a house; it looked institutional.

The school is such a great looking building to a little kid, big and old and kind of mysterious. It was exciting to go there and find out that it looked like some old mansion, where you can get lost or hide from people if you want to and not be found, and things like that. I remember just feeling joy at being at this place where I could do what I wanted where I wanted. The school was physically beautiful, and to be around this beautiful place and not be constrained was wonderful. The grounds were also incredible, and walking around on the rocks were really frightening! They were big. They were several times higher than I was, and people were jumping around on them. It amazed me that people were just going up there to this far away, scary place and nobody was attempting to make them not do that.
