OES is a pre-kindergarten through grade 12 college-preparatory, independent school that serves 870 learners from around the world. Since 1869, OES has helped learners develop solid academic skills, sound character, strong leadership abilities, and an appreciation for the value of hard work and giving back to the community. At OES, academics are a blend of traditional, research-based, cross-disciplinary, and experiential coursework. We believe learners learn best through experiences that fascinate them, so we create environments and explorations that open them up to the world.
