History	History INTL formed through the January 1, 2021 merger of Peninsula French-American School and Alto International School, uniting the two campuses under Silicon Valley International School (INTL). INTL offers Chinese, French, and German language programs for preschool through 12th grade, plus an Upper School Language Acquisition program and the full International Baccalaureate continuum. INTL traces its roots to 1979 when Peninsula French-American School opened as a French immersion school founded by Mme Charlotte de Géry with nine students. It became the International School of the Peninsula (ISTP) in 1996, moved to Palo Alto in 1999, was authorized for the IB Primary Years Programme in 2019 and for the IB Middle Years Programme later, and was renamed Silicon Valley International School in 2020.	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 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.
