All High School students in Grades 9-12 are working towards the completion of a four-year ISK High School diploma; many students also choose to pursue a second qualification in Grades 11-12 through the school's International Baccalaureate (IB) Diploma Program.
The International Baccalaureate (IB) Diploma Program at ISK provides High School students with a diploma and certificates recognized by universities throughout the world. Students may enroll in the full IB Diploma Program, requiring six externally administered exams, Extended Essay, and Theory of Knowledge Course, or they may also take specific individual IB courses for IB certificates. The maximum score possible in each IB course is 7. ISK has an inclusive policy in regards to the IB Diploma Program; it is open to all students who satisfactorily complete prerequisite courses.
