How to Apply

St. Sebastian's seeks to provide each prospective family ample opportunity to develop a genuine understanding of the School and its unique mission. Likewise, we hope to get to know each applicant and his family for their distinct gifts and qualities. Below is a breakdown of the Admissions process. Please use this as a guide, but always feel free to call us at 781-247-0125 if you have any questions.

Complete an Inquiry Form and Create a Ravenna Account

Please complete our Admissions Inquiry Form to get started with your process. You may also inquire via the Ravenna website (our online application provider) by "exploring" St. Sebastian's or beginning our application. Completing our Admissions Inquiry Form or exploring directly through Ravenna accomplishes the same task and allows us to be in touch with you. We will notify you of upcoming events and send you a viewbook packet in the mail (September through February). 

Get Started
To complete additional steps of the application process, you will need to create a Ravenna account if you do not already have one. Please be sure to use the same email address entered in the Inquiry Form for your login credentials.

Schedule a Virtual Interview & Tour 

A personal interview is required of every candidate. During this 60-minute meeting, you and your parent(s)/guardian(s) will meet with an admissions officer, so you can learn more about St. Sebastian's School and we can get to know you. Interviews are scheduled October 1 to February 8.

To schedule your interview, use your Ravenna account, which provides a calendar of available dates/times. You may also book your appointment by calling Helen Maxwell at 781-247-0125.
