Just with any school or daycare, the quality depends on the particular facility in your area. Ours in Mount Laurel, NJ is excellent and hands down the best preschool in our area. The children are not treated as if they are in day care. It is an advanced preschool. My daughter will be in "Creme Prep" and next year can be in Transitional Kindergarten as opposed to Pre-K, where she would be in all the other facilities in my area. You get what you pay for with preschool. I originally went to a horrible church run facility where somehow they allowed my child to fall into a toilet. All depends on where you are and the quality of the staff. You need to do your research on a variety of facilities in your area.
