Up to what age is the Montessori programme designed?
There are Montessori materials which are designed for use of children up to around 12 years of age. Whereas most Montessori schools are pre-schools, there is an increasing number of Montessori primary schools which work with children through all primary grades. There are a few Montessori junior and senior high school programmes. Dr. Montessori did discuss the education of children up to the college level. However, she specifically designed materials only for pre-school and primary 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.
