IB Programme Highlights

DP Core

CAS, TOK, and the Extended Essay -- required components of the IB Diploma -- stem from the Learner Profile. Students pursuing IB Certificates in individual classes do not pursue CAS, TOK, or the Extended Essay.

  • "CAS" stands for Creativity + Action + Service. Across junior and senior years, diploma candidates acrue at least 50 hours of planned and supervised activities in each category. Such participation is meant to encourage the appreciation of attitudes and values other than one's own, and to enable the student to communicate readily on both a philosophical and practical level.

  • "TOK" is the Theory of Knowledge course. This course -- an after-school seminar junior year and a year-long course senior year -- stimulates critical reflection on the knowledge and experiences acquired both inside and outside the classroom; evaluates the bases of knowledge and experience; and develops a personal mode of thought based on critical examination of evidence and argument.

  • The Extended Essay is a 3,500- to 4,000-word research paper on a topic of the Diploma candidate's choice. Development of this essay is guided by a faculty supervisor.


Diploma candidates take IB-level courses in each of six content areas:

  • Studies in Language and Literature
  • Language Acquisition
  • Individuals and Societies
  • Sciences
  • Mathematics
  • The Arts
