The short answer is no, but there is more to it than that.  Montessori schools are not franchises.  They are independently owned and operated.  Some are parent co-ops, some are run by a board of investors, and some are sole proprietorships.  The name Montessori is not copyrighted or trademarked so it can mean different things in different states.  Some states have regulations defining who may and who may not call themselves a Montessori school.  Virginia has no state regulations about this. 

We are very fortunate in the Washington area to have an abundance of Montessori schools.  Northern Virginia has seen an incredible growth in the number of Montessori programs in the past 10 years.  Parents are now seeking a school or a childcare facility providing more than just a place for the child to spend the day and they have realized that the Montessori approach of dealing with the whole child in a developmentally appropriate setting is what they are looking for. 

While there is a core program which all true Montessori schools share, there can be slightly different ways of implementing the program due to the teacher’s particular training.  Also, the Montessori Method is a dynamic, not a static pedagogy.  The teachers continually update their classrooms with new materials that reflect advances in toy design or technology, always adhering to Montessori principles in the organization and presentation of these materials.

There can be a different atmosphere from one school to another and even from one classroom to another within the same school due to the personalities and interest of the class.  for example, one class may have a teacher who is very soft spoken with a great interest in biology.  This teacher’s class may be very quiet and filled with plants and pets.  Another teacher who loves to travel has objects from all around the world.  A third may love to sing and dance so her class always has music in the background and the children love folk dances. 
After you have done all your reading, visited schools, talked to friends and relatives, the best way to decide which school is right for your child is going to be your own feelings.  we each have certain environments to which we respond positively or negatively.  There are some people with whom one has an instant rapport while there are others with whom you will have to spend more time to feel comfortable.  With the fine Montessori programs in this area you will surely be able to find one that suits the needs of both the children and adults in your family.
