Affording St. Sebastian's

The two most important questions you will ask during your admissions search are likely "What is the right school for my son and my family?" and "Can we afford it?"

As a School that believes in the pursuit of truth through faith and reason, we want to help you answer these important questions. If St. Sebastian’s and its combination of academic rigor and spiritual depth is the best school environment for your son and your family, please do not let the tuition prevent you from pursuing it. Students are encouraged to apply for admission regardless of their family's ability to meet the full cost of attendance.

Everything we do at St. Sebastian’s is focused on individual students and families. Likewise, financial aid is determined by each family’s unique financial situation. Please reach out to us at to schedule a call to discuss your financial aid qualifications. Through a confidential consultation, you can learn what your family can expect to pay in tuition—before you even decide to visit campus or complete our admissions application. Consultations are available from September through our financial aid deadline of February 1. They will help you feel good about making the best school choice for your son and the financially responsible choice for your family. 

Tuition for the 2022-23 academic year: $56,000

Daily lunch, provided to all students by the School, is included in the tuition fee.
