Our small size allows the children to move through their education fluidly, with attention to their individual needs. If a child is ahead of grade level, that's not a problem, and if a child is behind, that's also accommodated. I have a boy in my eighth-grade class who's doing high school senior level math. He has the ability to become a world-class mathematician, and we're helping him learn at a pace that's appropriate to his abilities. We're small enough that if a child has any kind of an issue, the entire faculty knows about it and can help the child.
Nothing is compartmentalized, and nobody falls through the cracks.
We also have a fabulous parent community. The parents are highly interested in their children's well-being, and it isn't unusual for a parent to share his or her special expertise in the classroom. One mother who's a scientist taught science for two years. It was a marvelous experience for the children, and for her. Another parent taught a unit on marketing and computers, in which he showed the children how to create a computer presentation, complete with text, charts, and slides.
