The focus of the International Baccalaureate Program is around the six areas of study represented by the hexagon shown below. A Diploma candidate must select one subject from groups 1-5. The sixth subject can either be selected from group 6 or a candidate may select an additional subject from groups 1-5. The 11th and 12th grade curriculum at Lee's Summit High School curriculum is a two-year program designed so students may qualify for the IB Diploma based on results from external exams and related requirements (Extended Essay, Theory of Knowledge, and CAS). Students may also choose to take one or more areas of study without working toward the Diploma. These students, referred to as Certificate candidates, only test within their area(s) of study.

Additional Diploma Requirements

  • Theory of Knowledge (ToK):  ToK is an interdisciplinary requirement intended to stimulate critical reflection on the knowledge and experience gained inside and outside the classroom. It is the cornerstone of the IB program. The course challenges students to question the bases of knowledge, to be aware of subjective and ideological biases and to develop the ability to analyze evidence that is expressed in rational argument.

  • Creativity, Action, Service (CAS):  The CAS component encourages students to share their energy and special talents with others. Students may, for example, participate in theatre or musical productions, sports and community service activities. Students should, through these activities, develop greater awareness of themselves, concern for others, and the ability to work cooperatively with other people.

  • Extended Essay of 4,000 words:  Each student has the opportunity to investigate a topic of special interest. The essay permits students to deepen their programs of study, for example by selecting a topic in one of their higher level (HL) courses. Or they might add breadth to their academic experience by electing to write in a subject not included in their program choices. The essay requirement acquaints Diploma candidates with the kind of independent research and writing skills expected by universities. The IB recommends that a student devote a total of about 40 hours of private study and writing time to the essay.
