History	History The International School of San Francisco is the city's oldest and largest bilingual school and was the first in the city to offer the International Baccalaureate, the fourth in the United States to do so. It began as the French-American Bilingual School (FABS), founded in 1962 by nine San Francisco Bay Area residents with close ties to France and opened in 1963. The school moved campuses several times—from Vincente Street in 1965 to Grove Street in 1967—and the high school program began in 1978, adopting the International Baccalaureate. In 1994 the school relocated to 150 Oak Street, and in 1995 the high school was renamed International High School. The Maternelle opened at 1155 Page Street in 2014; in 2024-2025 it renamed to The International School of San Francisco to reflect its bilingual and international mission.	History The Quarry Lane School was created by founder and president Dr. Sabri Arac in 1991. Dr. Arac earned a bachelor's degree in Metallurgical Engineering from Michigan Technological University and a master's degree and doctorate in Metallurgy/Materials Science from the University of Arizona, and spent his early career at Hewlett-Packard. He envisioned a secular, college-preparatory school spanning kindergarten through 12th grade with advanced instruction and a solid foundation. This passion culminated in the establishment of The Quarry Lane School. The Quarry Lane School is a nonsectarian, co-educational day school which supports a diverse faculty and student body.
Community	Community ISF hosts a year‑round calendar of community events, including an August Back‑to‑School Picnic, Grandparents and Grand Friends Day in November, and the Community Salon Series on topics such as biotechnology, neuroscience, political engagement, AI, and intellectual property as part of its Urban Engagement Program. There are monthly Principals Coffees for parents and regular Parent Education sessions to support families. PoSoC, a monthly affinity space for parents of students of color, and schoolwide service activities such as Days of Service and a Schoolwide Day of Service are also part of campus life.	Community Building a strong community between parents, teachers and students is a key component of Quarry Lane's preschool programs, which strive to create an inclusive culture that celebrates diversity and supports community outreach. The school uses the Tadpoles system to maintain safe, secure communication with families, delivering daily updates, photos and alerts. Developmental evaluations are conducted from young preschool through pre-kindergarten, with regular parent/teacher conferences available and special conferences as needed. Throughout the year, campuses reach out to the nearby community through charitable events such as fall food drives for the Alameda County Food Bank, sponsoring local families in winter, and events like Valentines for Veterans and Trike-a-thon to foster compassion and service.
