Study the US High School Diploma
The CGA US Diploma is an online, project-based program that empowers students to take classroom concepts and expand on academic ideas to solve real-world problems and develop digital portfolios that capture their unique talents and vision of the world.
We pride ourselves on providing the perfect mix of project-based, career-focused courses and academic rigor. Students typically graduate with a comprehensive portfolio of project-based work as well as the completion of several AP exams, demonstrating both real-world accomplishment and robust academic achievement.
Our classrooms are engaging and global. Our graduates go on to attend some of the world's most competitive universities.
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.
