The admission process starts with a scheduled tour of the school. We recommend that this first visit, if possible, be without your child. During this time, parents can talk with one of the directors about the approach, philosophy, and methods of the school.  Interested parents fill out an application and pertinent forms.  

We invite you to take the first step and contact our Head of School Tomo Takahashi at (425) 888-3369, or by e-mailing admissions@mtsiarbor.com .com , to schedule your tour at Mt. Si Arbor Montessori School.

Acceptance – All sources of information, including available openings, are considered when making decisions about student acceptances. Mt. Si Arbor Montessori School siblings are given a priority, as are students with previous Montessori experience. Families will be notified by the first week in April regarding status of acceptance to Mt. Si Arbor Montessori School and obligation for registration and payments.   A placement is secured upon completion of the Enrollment Contract and receipt of tuition deposit. Acceptance is conditional during the first month of school attendance.
