Age - Grade Conversion Charts

We hope this chart will be helpful to you and your family. As a reminder, the OIS Admissions Policy states:

OIS takes into consideration the birth date of the student, the system the applicant is transferring from,  and the grade level most recently completed. For younger students, developmental readiness is also evaluated. The goal is to place students with age-appropriate peers in the next logical step of their curricular path in order to predict a high level of academic and social success.
