We check clusters in a couple of ways--testing against a split half and using the cluster results in a discriminant analysis to see if it predicts the variables from which the clusters are derived--Here's a link to a memo on our process for clustering. http://www.chestnut.org/LI/downloads/training_memos/Cluster.pdf
