Léman Manhattan Preparatory School Curriculum: IB / American 2026

International Baccalaureate World School, English-medium. The IB Diploma Programme (Grades 11–12) is the confirmed IB authorization on the school's own pages — students take either the full IB Diploma or individual IB Course Certificates. The school describes an 'IB approach' beginning in early childhood, and third-party directories assert a full PYP/MYP/DP continuum, but PYP and MYP authorization are NOT corroborated on Léman's official site and should be verified at ibo.org before relying on them. No Cambridge/A-Level route.
