Winsor's Admission team looks diligently at every girl who applies, seeking students with demonstrated intellectual curiosity, academic ability, motivation, and spirit. Winsor welcomes applications for grades 5 through 7 in our Lower School, and for grades 9 through 11 in our Upper School. Most students enter Winsor in the 5th, 6th, or 9th grade. Openings in grades 7, 10, and 11 are more limited.
We welcome your application for the 2020-2021 school year.
The admission process begins in September and ends in January for admission during the following school year (please see important dates and deadlines). Admission decisions are available online in March.
As a day school without SEVIS certification, we cannot issue I-20 visas or accept student applications from citizens of other countries.

  • Visit

    Step 2: Visit

    Tours and Interviews
    Call the Admission Office at (617)735-9503 to schedule a tour and interview. Our interview schedule (mid-September through January) fills very quickly, so we encourage you to call as soon as possible in the fall. The only item you are required to submit before your arrival is the preliminary application (Step 1). Every visit is carefully crafted to ensure that you and your student have the most personal and pleasurable experience at Winsor. During a typical visit*, you can expect: A 30-minute tour of the school conducted by a high school student guide. A 30-minute conversation between a Winsor admission representative and the parent(s) or adult(s) who accompanied the student. This gives the admission representative a chance to learn more about the student and family and gives parents a chance to ask questions. A 30-minute conversation between the admission representative and the student.

    Please arrive promptly in order to respect the tour guide’s limited time and to get the most out of your tour before the guide's next class or commitment. Parking is available on site. (Get directions to campus.)

    *If your student is applying for Class I/fifth grade, the student will participate in a specially designed group activity in lieu of the individual student interview.
    Open House
    We schedule Open House on a weekday in November so you can see the school in session and sit in on classes. You have the opportunity to meet teachers, students, and parents, and hear their perspectives on what makes Winsor special. Adults are strongly encouraged to attend, and students are also welcome. No RSVP is required. Please see the admission calendar or call our office at (617)735-9503 for more information.

    School Fairs
    Our Admission team also attends school fairs off campus in the fall. See our admission calendar for more information about these events.
  • Test

    Step 3: Test

    Register for and take the appropriate standardized test. You must take the appropriate test by the middle of December at the latest.

    For entrance into grades five-seven, register for the Independent School Entrance Exam ISEE online (Winsor's code is 220405) or by phone at (800)446-0320. It must include the essay portion.

    For entrance into grades nine-eleven, register for the SSAT * (Winsor's code is 8245) or by phone at (609)683-4440.
    Please note: Winsor does not encourage or recommend that your student take the exam more than once. Winsor does not "superscore" and so will view all results.
    *For students applying to Class V (ninth grade) and above and thus taking the SSAT:
    The Character Skills Snapshot
    Character and personal growth are an integral part of an education. Grades and test scores don't tell the whole story of any student. The Character Skills Snapshot gives richer holistic information and illuminates areas where Winsor can help your student grow and thrive.
    Winsor recommends taking The Character Skills Snapshot along with the SSAT. Once a student registers for an SSAT date, s/he will have free access to The Snapshot.
