International Baccalaureate Diploma Program

The International Baccalaureate (IB) Diploma Program is a challenging two-year curriculum over grades 11 and 12. The curriculum incorporates six academic subject areas. IB Diploma students must select one subject from each of the six subject groups. At least three and no more than four are taken at higher level (HL), the others at standard level (SL). For each course, the mark is based on a combination of internal and external assessments. Along with the six subject groups, an IB Diploma student must fulfill the core requirements of the Extended Essay (EE), Theory of Knowledge (TOK), and hours of Creativity, Action, and Service (CAS).

ACS students with an interest in the IB Diploma Program complete an application in the spring of grade 10. It is important for students to review their graduation requirements and their course selections. A combination of strong study skills, time management, and determination are essential for success. After the students submit the application, a placement committee analyzes the course selections and activities to make admissions recommendations. Any student wishing to take 4 HL courses needs the prior approval of the course instructors, IB coordinator, high school principal, and counselor. Taking 4 HL courses is not encouraged due to the extreme workload of higher-level courses.

Students enrolled in IB courses for the diploma or certificates have internal and external assessments. External assessments are held in early May. It is the responsibility of the student to pay registration and assessment fees. Students in HL courses receive weighted grades of 0.5 whereas SL courses receive 0.25. For additional information about the IB program, please refer to the HS Student Handbook.
