The Creative Curriculum is now on its 5th (I think) edition so it is possible that there have been some changes that might show more effects. But generally, I would look at preschools that tout this as simply describing how they organize themselves. As has been mentioned, implementation can vary so widely. But the strongest research on the program (that is, research that was done by an entity other than the program's creators) find it neither harmful nor particularly helpful for a child's development. There are other curricula that have shown through research to have stronger positive effects.
