There are Montessori Materials that are designed for use by children up to around 12 years of age. Whereas most Montessori schools are preschools, there are an increasing number of Montessori elementary schools that work with children through the sixth grade. There are a few Montessori junior and senior high school programs. Dr. Montessori did discuss the education of children up to the college level. However, she specifically designed materials only through the elementary school years. This was because she felt specially designed materials were only needed for the younger children since the older children would have the competence to learn with materials commonly available.
