Core requirements To be awarded an IB diploma, candidates must fulfill three core requirements, in addition to passing their subject examinations: • Extended essay (EE). Candidates must write an independent research essay of up to 4,000 words on 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 exhibition or 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. Three or four subjects must be taken at Higher level (HL) and the rest at Standard level (SL). The six IBDP subject groups and course offerings are summarised below. More information about the subject groups and individual courses can be found at the respective subject group articles: •
Group 1: Studies in language and literature. Taken at either SL or HL, this is generally the student's native
language, with over 80 languages available. As of courses starting in summer 2011, there are two options for Language A (previously A1): Literature, which is very similar to the old course, and Language and Literature, a slightly more challenging adaptation of the former Group 2 Language A2 subjects, which have been withdrawn. The interdisciplinary subject
literature and performance can also be taken at SL. •
Group 2: Language acquisition. An additional language, taken at the following levels:
Language B (SL or HL), or
Language ab initio (SL only). Language B courses are meant for students with some prior experience in the language, while Language ab initio is meant to be taken by pupils who are complete beginners, with almost no experience. Latin and Classical Greek are also offered and may be taken at SL or HL. •
Group 3: Individuals and societies. Humanities and social sciences courses offered at both SL and HL: Business Management,
Economics,
Geography,
History,
Information Technology in a Global Society (ITGS),
Philosophy,
Psychology, and
Social and
Cultural Anthropology and Global Politics. The course
World Religions is offered at SL and the interdisciplinary course
Environmental Systems and Societies is offered at SL or HL. •
Group 4: Experimental sciences. Five courses are offered at both SL and HL:
chemistry,
biology,
physics,
design technology and
computer science. The course
Sport, Exercise and Health Science is offered at both SL and HL. The interdisciplinary course Nature of Science is offered at SL only, while
Environmental Systems and Societies is offered at SL or HL. •
Group 5: Mathematics. All students hoping to graduate with an IB Diploma must take a math class, with courses available at different levels and with different focuses. There are two distinct IB Math courses, both available at standard or higher level:
Mathematics: Analysis and Approaches, with an emphasis on algebraic methods, calculus, and mathematical thinking, and
Mathematics: Applications and Interpretation, with an emphasis on modelling and statistics, and with a focus on using technology to solve problems with real-world applications. These curricula were introduced in major changes in 2019 and 2021
, replacing the previous curricula with a new structure. Under the 2019 course changes, Further Mathematics were dropped entirely. Before 2019, of increasing difficulty, the courses offered were
Mathematical Studies SL,
Mathematics SL and HL, and
Further Mathematics HL. The
computer science elective courses were moved to Group 4 as a full course from first examinations in 2014. •
Group 6: The arts. There are five Courses offered at both SL and HL:
Dance,
Music,
Theatre,
Visual Arts, and
Film. Instead of taking a Group 6 course, students may choose to take an additional course from Groups 1–4, or a school-based syllabus course approved by IB. The interdisciplinary subject
literature and performance is also offered, although currently only at SL. Environmental Systems and Societies SL or HL is an interdisciplinary course designed to meet the diploma requirements for groups 3 or 4, while literature and performance SL meets the requirements of Groups 1 or 6.
Online Diploma Programme and pilot courses The IB is developing an online version of the IBDP and currently offers several online courses to IBDP students. Eventually, it expects to offer online courses to any student who wishes to register. Additionally, the IB has developed pilot courses that include World Religions; Sports, Exercise and Health Sciences, Dance, and a transdisciplinary pilot course, literature and performance, Global Politics. These pilot courses have now become part of the mainstream courses. ==Assessment and awards==
