Are the children divided into classes by grade, as in the public schools?
No, not really. As a rule, children working at Kindergarten through second grade levels meet Downstairs and children working at grades third through eighth grade levels meet Upstairs. The two large groups are frequently subdivided into skill groups and project groups of various sizes depending on curricular need. Important are such factors as reading ability, social and emotional maturity, special interest, and group dynamics. It is also recognized that a single child might be operating at very different skill levels in different subjects or project areas.
