Changes

*Implement the cluster over three years. For the purposes of transition, assign sophomores to clusters in 06-07, but maintain the roomdraw for rising juniors and seniors to fill in the housing spaces that are left after the cluster roomdraw. This will prevent seniors and to a lesser degree, juniors, from being thrown into a bath of ice water with respect to clusterization. Then in 07-08, assign new rising sophomores into clusters, keep the rising juniors in their clusters, and allow the seniors to be last (class) pick free agents. Then, in 08-09, your masterpiece will be complete and you'll be glad you didn't rush things.

*Get more statisticians and social psychologists on the CUL.
