The Bryn Mawr School is pleased to be affiliated with the Online School for Girls. Since its founding in June 2009, the Online School for Girls has partnered with the Online School for Boys to become One Schoolhouse, which has both co-ed and single-gender opportunities. OSG/One Schoolhouse has grown from four schools to 169 schools from coast to coast and around the world, and from 16 students to hundreds. Any girl, anywhere in the world, can enroll in the Online School for Girls, provided she meets the admission standards for the school and prerequisites for a course.
