IB Diploma


The International Baccalaureate Diploma (IB Diploma) is a two-year Diploma for classes 11 and 12. The program is more practical and application-based. It has a broader spectrum of subjects that lead to all-round development. It ensures a strong university entry credential. It prepares students to succeed in higher education, with essential skills such as self-confidence, preparedness, research skills, organisational skills and active self-learning skills. The methodology focuses on 'learning how to learn' rather than 'what to learn'.

To be awarded an IB diploma, a candidate must fulfill three core requirements, in addition to passing his or her subject examinations

Extended essay (EE). Candidates must write an independent research essay of up to 4,000 words in a subject from the list of approved EE subjects. The candidate may choose to investigate a topic within a subject they are currently studying, although this is not required. The EE may be written on an interdisciplinary topic.

Theory of knowledge (TOK). This course introduces students to theories about the nature and limitations of knowledge (basic epistemology) and provides practice in determining the meaning and validity of knowledge (critical thinking). It is claimed to be a "flagship element" of the Diploma Programme, and is the one course that all diploma candidates are required to take. TOK requires 100 hours of instruction, the completion of an externally assessed essay of 1600 words (from a choice of six titles prescribed by the IB worth 67%), and an internally assessed presentation (worth 33%) on the candidate's chosen topic.

Creativity, activity, service (CAS). CAS aims to provide students with opportunities for personal growth, self-reflection, intellectual, physical and creative challenges, and awareness of themselves as responsible members of their communities through participation in social or community work (service), athletics or other physical activities (activity), and creative activities (creativity). The guideline for the minimum amount of CAS activity over the two-year programme is approximately 3–4 hours per week, though "hour counting” is not encouraged. Previously, there was a requirement that 150 CAS hours be completed, but this was abolished in 2010. However, some schools still require these hours.
