Admissions Process

Our admissions process begins in the fall one year before the desired year of entry.

Open Houses are designed to help you get to know our school before or after submitting an application. Due to Covid-19 restrictions, we will be utilizing Zoom. During these evening parent events, you will have an opportunity to ask questions, to virtually tour classrooms, and to hear from both WSMS faculty and parents. Additionally, Mimi Basso, our Head of School, will discuss the philosophy and mission of West Side Montessori School.

Parents are invited to attend a Zoom Open House before or after submitting an application.

Reservations are required. Please click here for more details.

The online application for the 2022-2023 school year became available on September 20, 2021. The application deadline is January 7, 2022. We treat all applications submitted by the January deadline with equal care and consideration. Please note that in order to meet the ISAAGNY notification dates, all appointments must be completed by February. The $50 application fee is submitted by credit card with the online application. Fee waivers are available for families applying for financial aid. Please call the front desk to request a fee waiver.

Classroom observations will be by Zoom this year due to covid-19 protocols. Although our building will be closed to the public, we hope a Zoom session will give you a glimpse of our engaged children, dynamic teachers, and beautiful classrooms.

After you have submitted your application, you will receive an email with information about scheduling your Zoom classroom observation. These group sessions are for parents and are held on weekdays from mid-October through January. Parents of sibling applicants are not required to attend.

After your classroom observation, you will be invited to schedule a parent interview. During this 30-minute visit, parents meet with a current or alumni WSMS parent from our Admissions Committee. Parent interviews are mostly held on weekday mornings, but some afternoon appointments may be available depending on interviewer availability. The parent interview provides an opportunity for you to share individual information about your child and family. Equally important, it provides a time for you to gain additional information about the school from the perspective of a parent.

There will be no child group visits this year.

After submitting the online application, families who have indicated that they will be applying for financial aid (FA) will be sent information by email about submitting an FA application. We use a system called SSS to process financial aid applications. The SSS application is available beginning in September. There is a fee of $55 due to SSS at the time of application. A limited number of fee waivers are automatically assigned through SSS based on financial information that you supply to the system.

We notify families who have completed the application process by email in accordance with ISAAGNY notification dates. Families who have been accepted will be sent a contract and must return the signed contract and deposit by the ISAAGNY reply deadline in order to enroll. We maintain an active wait list during the parent reply period and notify families as spaces become available.

West Side Montessori School welcomes students and families of any race, color, sexual orientation, or national or ethnic origin. We do not discriminate on the basis of race, color, sexual orientation, or national or ethnic origin in administration of our educational policies, admissions policies, scholarship and loan programs, and other school-administered programs.
