If you barely go over the minimum size, it will be a little more expensive to handle that class. Numbers just don't shake out perfectly. White would like to see systems able to use a paraprofessional to assist a teacher in situations where classes are just barely over the maximum size. But it will be required to spend that and more. That's more than offset by the number of extra teachers you've got to hire.
People ask, where's the bricks and mortar.
Commerce has 50 such students currently, most of them in kindergarten. One of White's biggest concerns is the creation of a new governing board, the creation of local school councils. These people would be appointed, two by the school PTA or PTO, two members of the faculty and chaired by the school principal. That committee would appoint a sixth member. The result would be only three more school committee meetings a month in the Commerce system, but in the Jackson County School System, each of its eight schools would have a school advisory council.
