Q: How can I tell a "good" Montessori school from the rest?

Obviously the definition of a good school is open to interpretation. However, in order to determine whether a school offers the Montessori Method as conceived by Dr. Maria Montessori, ask whether the instructors and assistants are certified by the Association Montesssori Internationale. Also, ask if the classroom materials are authentic Montessori materials certified by AMI. You will notice that most authentic Montessori materials are not made of synthetic materials like plastic or rubber. Rather, they are made of wood and polished glass, organic substances which children find inherently beautiful and fascinating.
