Applying to Riverdale requires a number of steps because we want to know our applicants and their families in many ways. As you begin the process, please contact us at with any questions. We welcome an opportunity to connect with you.

Get to Know Us
We encourage you to join us for one of our many admission events, which are designed to help you and your family get to know our school. Please visit our events page to learn about what we offer and how to register.

Apply Online
Complete our application by creating an account in Ravenna at Look for Riverdale Country School in the Online Directory. From there, you will be able to submit the admission application. Applications for the 2020-2021 will be available by noon on September 8, 2020. The Preliminary Forms (admission application) are due on Monday, November 16, 2020, and the Final Forms (all supplemental materials) are due on January 8, 2021. 

Note to applicants for Grades 1-5, 8, 10-12: We consider applications to these grades based on attrition. Financial aid for these grades is limited. Please see more information in Ravenna.

Schedule an Online Interview
The best part of the admission process is speaking directly with our applicants. We require an online interview for each child who is applying to the school. The sign-up process varies by grade. Please visit your Ravenna account for more details. We will begin scheduling interviews on September 15, 2020.

Request Recommendation Forms and Transcripts
Once an applicant has created an account in Ravenna, they will be able to generate the required school forms. All teacher evaluations are due on January 8, 2021.

Register for Testing
At Riverdale, we like to get to know our applicants in as many ways as we possibly can. We believe that testing/assessments can be one way for our applicants to demonstrate their strength as students, and as such, we have testing requirements for entry to several grade levels. Details about our online assessment for Kindergarten applicants will be available in Ravenna on September 21, 2020. Students applying to Grades 5-12 must take the ISEE (Independent School Entrance Exam) or SSAT (Secondary School Admission Test).

We ask applicants to grades 9-12 to complete the Character Skills Snapshot, an assessment tool that provides our admission team with additional information about your child’s strengths beyond the grades and test scores. For more information, please visit SSAT.

There is no required testing for students entering Pre-Kindergarten or Grades 1-4.

Riverdale offers more than 70 teams, which attract experienced athletes as well as those who are new to a sport.
The Upper School Summer Science Research Program gives students an opportunity to take part in two ongoing environmental studies.

Entry Points

Riverdale considers many factors when creating a class, including gender, diversity, ability, and age range. The birth date range of September 1st to September 1st typically works well for our program (students who are entering PreK in fall 2021 born between 9/1/16 and 9/1/17, students entering kindergarten between 9/1/15 and 9/1/16, etc.), but we are happy to discuss your child’s placement during the interview.

Key Admission

All admission decisions will be communicated electronically on the specified ISAAGNY (Independent School Admission Association of Greater New York) mailing dates. If a child is admitted to Riverdale and a family chooses to enroll, we will require a signed enrollment contract and deposit by the ISAAGNY reply deadline. These notification dates apply only to those applicants who have met the application deadlines.

Our application process for international students is the same as it is for all applicants. We do not require the TOEFL. Prospective families should complete the application process on their own as we do not work with any placement agencies. We are able to write I to 20 visas once a student has enrolled at the school. Riverdale is a day school, and we do not provide housing or homestays.
