The Extended Essay

A 3,500 - 4,000 word research essays complete as part of the diploma. This independent research paper is done with guidance from a faculty advisor. Students choose a topic and a teacher "advises" them through the essay. The essay is assigned second semester of the first year in the IB diploma program and is due the following year. TOK and the extended essay combine to give students up to 3 points on their final IB diploma score.

Creativity, Activity, and Service (CAS)

Creativity, Activity, Service (CAS) is at the heart of the Diploma Program. It is one of the three essential elements in every student’s Diploma Program experience. It involves students in a range of activities alongside their academic studies throughout the Diploma Program. The three strands of CAS, which are often interwoven with particular activities, are characterized as follows.

  • Creativity: arts, and other experiences that involve creative thinking.
  • Activity: physical exertion contributing to a healthy lifestyle, complementing academic work elsewhere in the Diploma Program.
  • Service: an unpaid and voluntary exchange that has a learning benefit for the student. The rights, dignity and autonomy of all those involved are respected.

Officially CAS is completed during both years of the 2 years of the diploma program.  Students will do a variety of activities over the 2 years, write reflections of these activities in a portfolio, and meet with the CAS supervisor to complete the CAS requirement.

Theory of Knowledge (TOK)
TOK is only available to IB-diploma candidates

A course that teaches the thoughtful and purposeful inquiry into different ways of knowing, and into different kinds of knowledge, TOK is composed almost entirely of questions. The most central of these is “How do we know?” Students taking TOK become aware of the interpretative nature of knowledge, including personal ideological biases, regardless of whether, ultimately, these biases are retained, revised or rejected.
