What Saint Mark’s School does
Saint Mark's School is a private, nonprofit 501(c)(3) independent Episcopal school founded in 1960, serving approximately 218 students from preschool (starting at age 2 years 9 months) through grade 6 across two academic divisions — Lower Elementary (Developmental Kindergarten through Grade 2) and Upper Elementary (Grades 3-6). Its academic program is built on the Responsive Classroom approach to pair academics with social-emotional learning, Singapore Math (Dimensions curriculum) for mathematics, Orff-Schulwerk and Kodály for music, and a 1-1 iPad program for grades 3-6 with a digital literacy and computational thinking curriculum. Enrichment spans Spanish, art, physical education, library, technology, and weekly chapel.
The school generates revenue primarily through annual tuition subscriptions ranging from $10,950 to $27,750 per student (with $500–$1,000 in registration fees), supplemented by Extended Care (before/after-school care from 7:30 AM to 6:00 PM), the Saint Mark's Summer program (early-bird pricing from $660 to $2,875), and Annual Fund contributions that represent roughly 10% of the operating budget. Approximately 30% of students receive tuition assistance with average awards exceeding 50% of tuition. The Legacy Endowment (established 2015 with $2 million in contributions) provides a permanent reserve.
Saint Mark's go-to-market is direct-to-consumer and family-initiated: prospective families submit inquiries, schedule campus tours, complete applications with teacher evaluations and transcripts, participate in parent interviews, and undergo age-appropriate screenings. The school's distribution is entirely domestic (Southern California, primarily the Altadena/Pasadena corridor), supported by EF Academy and Church of Our Saviour acting as temporary campus hosts after the January 2025 Eaton Fire destroyed the original Altadena campus. The school is fully accredited by CAIS and WASC, holds NAIS membership, and is affiliated with the National Association of Episcopal Schools and St. Mark's Episcopal Church.
