explore our CAMPUS

What's cool about our campus is that it's spread out over seven acres in Philadelphia's historic neighborhood of Germantown. The buildings are an eclectic mix of old and new, a unique look and feel more consistent with a college campus. With three gyms, three auditoriums, a student center, numerous open, green spaces and nine classroom buildings, it's a place worthy of adoration and exploration. The Meetinghouse, at the center of it all, provides a beautiful and spiritual focal point.

The Pillars of A

Quaker Education

At GFS, students and teachers gather in Meeting for Worship once each week. This is a time for shared, silent contemplation. Anyone who feels moved to speak may rise and do so. It is a simple formula, and can be a remarkably powerful experience.In these days of constant connectivity, the ability and opportunity to sit in silence have special value. Meeting for Worship is a cornerstone of the GFS culture that many come to cherish throughout their lives.

The math program strives to equip each student to think logically and analytically and to effectively communicate strategies for solving problems, both of a theoretical and practical nature. We seek to develop a student’s understanding of algebra and other mathematical concepts throughout the curriculum. Topics in each subject are explored through multiple representations and modalities. Scientific and graphing calculators as well as various software applications are used as instruments for exploration and deeper understanding. Our aim is to make the study of mathematics an exciting adventure that takes our students on an intellectual journey filled with practical and engaging experiences.

Placement in accelerated courses is based on student performance, teacher recommendation, and the approval of the department head. These courses move at a faster pace and explore topics in greater depth and breadth. Most students complete a college-level calculus course.
