Course Catalog
US High School Diploma Curriculum
In every course, students work in an inquiry-based classroom with teachers and peers to expand their knowledge and transfer academic concepts across content areas. Exploring how academics and the world are interconnected gives education a new level of relevance. Throughout a student’s time enrolled in the US Diploma Program they will build portfolios that encourage reflection, and allow them to showcase their mastery of course material.
