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.

Create a Ravenna Account to Inquire and Start the Process 

A Ravenna account is necessary to register for admissions events, to schedule an interview, and to complete our application. When you create an account and “explore” St. Sebastian’s, we will also include you in our email list and mail you an information packet and viewbook (September through February).  

Ravenna Steps: 
  • Create a Ravenna profile with an email address that you will have for the entire admission process. 
  • Click “EXPLORE” to indicate your interest in learning more about the school and the admission process. (If you already have a Ravenna account, simply log in and EXPLORE St. Sebastian’s). 
  • Click “APPLY” to indicate your interest in starting the application process (scheduling an interview/viewing admission requirements). Clicking “Apply” does not require you to submit an application or pay the application fee.  

Note: Completing our Request Information Inquiry Form or “exploring” us directly through Ravenna accomplishes the same tasks.  It allows us to be in touch with you, and it allows you to start the process. 

Get Started

Schedule a Personal Interview & Tour 

During a personal interview, you and your parent(s) will meet with an admissions officer to learn more about St. Sebastian's.  The interview is required of every applicant so that we can get to know you better.  We schedule interviews from October 2 to February 2.  You may choose an in-person or a Zoom interview as you prefer.
