West Side Montessori admits students of any race, color, national and ethnic origin to all the rights, privileges, programs, and activities made available to students at the school. The school does not discriminate on the basis of age, national origin, race, gender, or disability in the administration of its educational policy, admission policy, or any school administrated program.

West Side Montessori has an inclusive philosophy and values diversity in the school population. All children are assessed by the Admission and Placement Committee to ensure that resources are available to meet the child's individual needs.

The school prefers to admit children at a very young age so that the unique learning experiences in the Montessori environment can provide the necessary foundation for further learning. Preference is given to siblings of currently enrolled students and students transferring from other Montessori schools. When considering students for enrollment, the Admissions and Placement Committee assesses the application on the basis of the school's guidelines for placement.
