Central Park School for Children
[http://www.centralparkschoolforchildren.org/ Central Park School for Children] is a Magnet School on the Durham Public School system. Being a magnet school, however, they are not bound by all the same rules, and their approach is rather more flexible. Class sizes are also smaller. The main downside is that admission is by lottery.
CPS with Harena's youngest, Benjamin, has been very positive. I (W.) will probably have more to say about this when time permits.
