My son is in the Pre-K class at plymouth center. I would say that this school is just average, teachers are good but I don't think they work with the kid as much as advertised in the brochure etc. I love teaching my son by myself at home and i did not feel that he learn everything from the school. I believe parents who don't work on their kids at home may see lot of value in the learning area however, my experience has not been the same. Moreover, the center director Ms. Shirley is a horrible person. She is not at all helpful or supportive. She lied to us about corporate discount and made excuses and stories. Finally, i had to show invoice of my friend, who works with me and was getting the same discount. The center is closet to my work otherwise, i would say its just an okay place. I believe Montessori teaching is a much hyped topic and centers like this are making lot of money out of it.
