High School Admissions


Our Classical High School is Now Accredited!


At St. Monica, we recognize that choosing the right school for your child is a significant decision. Our goal through the admissions process is to develop a thorough understanding of each student who applies while providing an opportunity for you to experience the school and connect with our community.

Since 2020, St. Monica Catholic School on Mercer Island has offered a Catholic classical high school education. St. Monica will be accepting applications for its Fall 2025 this September. A classical liberal arts school focused on nurturing clarity of thought and love for truth as guided by the wisdom of the Catholic Church, St. Monica’s high school program forms students in wonder and virtue through close-knit learning cohorts taught by expert, faith-filled faculty.

Students and families interested in St. Monica Catholic High School begin the admissions process by creating an account in Finalsite (formerly SchoolAdmin), our online application management system. Through Finalsite you can submit an application, complete supplemental forms, request teacher evaluations and transcripts and track the status of your application online. No exam required.


For applicants applying from other Catholic schools, this form is completed by their 8th grade teacher and submitted to us for you. Homeschool families will need to submit these forms directly.
