1. Start the online Ravenna application and register for an admissions tour. Admission is selective and Léman Manhattan cannot admit every applicant, so begin the online process early. The birthday cut-off for PK2, PK3, PK4 and Kindergarten is December 31 of the enrolled school year. Applications are submitted on Ravenna for Léman Manhattan. 2. If you will seek financial aid, indicate this on your child's application.

The Preliminary Application includes basic contact information, educational history, and a student/guardian statement; Supplemental Materials differ by grade and may include school reports, teacher letters and standardized test scores if required. 4. Follow the published timelines by grade; Regular Admission follows ISAAGNY and Rolling Admission may occur on a space-available basis after the final ISAAGNY dates. 5. If admitted, enroll by the specified deadline, sign the enrollment agreement and have tuition payment (deposit or pay in full) clear by the deadline; extensions are not guaranteed for spots or financial aid.

A need-based financial aid program provides awards to newly admitted students based on demonstrated financial need. Financial aid is based on need and UNIS uses its own Financial Aid form; an aid application will not prejudice admission decisions. Financial aid decisions are coordinated after admissions decisions, and submission timing helps the process. SSS begins processing financial aid information on November 1, 2025; it is recommended to submit by December 31, 2025 for consideration in the February/March notification cycle. For more information on eligibility and process, contact Margaret Chiu at (212) 584-3034 or mchiu@unis.org.
