Our priority deadline is January 31.

Completing your application before the priority deadline gives you the best chance of being accepted. Plus, when you apply before Jan. 31, you find out your acceptance status in early March, so you have plenty of time to make the most informed decision possible for your family.


1. Submit an inquiry.

An inquiry provides us with some basic information about your family so we can give you the information you need. It also creates your applicant account, so you can log into the Admission Portal and begin your application.
