What is Validation?  The Maryland State Department of Education has mandated the establishment of "Montessori Validating Organizations" which are responsible for informing the State as to which programs meet the criteria to call themselves "Montessori Schools."  Every Montessori School in Maryland must be Validated.

* Schools seeking Validation, please visit our Validation Process page.

In order to Validated, each school must meet the following criteria:

  • The school must have a philosophical approach to education that is consistent with the educational methods and areas of instruction of Dr. Maria Montessori;

  • The school must have an established student teacher ratio for each age group for which they seek validation;
