I just wanted to share that there is an awesome preschool in Tucson called Tucson Community School. It is a private cooperative school so there is tuition and they have a 3yr old class, a 4yr old class and a kindergarten that is accredited. As a co-op the parents have tremendous input (and duties) with the school and it has been around for 60 years!!!!! So totally awesome are the yards, the classrooms, the class sizes (1:4 ratio), the gardens, the ducks and chickens, the moms and kids..... I could go on and on.
