The Flossmoor Montessori School continues the creative individual and social education begun by the physician-educator, Dr. Maria Montessori.
Recognizing the unique potential of the child, Dr. Montessori was successful in understanding and assisting the child in the course of fundamental human development - that of becoming an adult.
For the child shows us a universal pattern of development and this pattern reveals sensitive periods, short intervals during which the child is disposed to create some part of himself using what the environment provides.
Walking and speaking at predictable times are illustrations of this phenomenon in very young children. By addressing these sensitivities and providing psychologically appropriate activities in the right way, Montessori education helps the child build himself physically, emotionally, intellectually and socially.
The School admits children of any race, color and ethnic or national origin.
Acceptance of children is on an individual basis with consideration given to class composition and available space and programs.
The School is a tax-exempt, not-for-profit organization. Flossmoor Montessori School is accredited by the Association Montessori International and belongs to the Illinois Montessori School System.
The faculty consists of directresses who hold Montessori diplomas issued by accredited training courses; assistants; an administrator and support staff.
