Choosing IB Diploma Programme subjects is more than just ticking six boxes on a timetable. Each choice can affect how manageable the two years feel, and in some cases, which university courses are still open later.
When comparing International Baccalaureate schools, it’s also worth checking what subjects each school actually teaches. Students choose from six groups, mixing higher-level and standard-level options as they complete the DP Core.
This guide helps parents and students understand the IB DP subjects by group, the difference between Higher Level and Standard Level, and what to consider when choosing the right subject combination.
What is the IB Diploma Programme? A Quick Overview
The International Baccalaureate Diploma Programme is a two-year education programme for students aged 16 to 19, and follows on from the IB PYP curriculum in the IB continuum. Students study six subjects and also complete three core components: Theory of Knowledge, the Extended Essay, and Creativity, Activity, Service.
The programme aims to give students a broad academic base rather than requiring them to study all subjects in equal depth, continuing the inquiry-based approach students first encounter in the IB MYP Curriculum. Some subjects are taken at a higher level and some at a standard level so that students can follow more closely areas which interest them, which they are good at, and which they intend to study further.
The 6 IB DP Subject Groups Explained
The IB diploma subjects list falls into six groups. They cover languages, humanities, sciences, mathematics, and the arts together. Most students will take one from each group, although there is some flexibility in the final combination.
Group 1: Studies in Language and Literature
The group is based on a language that the student knows. Students analyse the use of language and the construction of meaning and how texts of different kinds communicate ideas. It includes: Language A (Literature); Language A (Language and Literature), and Literature and Performance.
Group 2: Language Acquisition
It is for learning a second language, but the course is based on the student’s current level. The ab initio language is only available at the standard level and is for beginners. Language B is for students who have some experience of the language and can be taken at either the standard level or the higher level. Another choice is Classical Languages.
Group 3: Individuals and Societies
This category is a broad group, generally attracting students who like to understand people, behaviour, economies, politics or societies. Subjects: Business Management, Economics, Geography, Global Politics, History, Philosophy, Psychology, Digital Society, Social and Cultural Anthropology, World Religions. The student’s decision is based on personal interest as well as future study plans.
Group 4: Sciences
Environmental Systems and Societies is a bit different, as it is interdisciplinary and can meet the needs of Group 3 and Group 4. Those wanting to study medicine, engineering or other science-based degrees should check university subject requirements before making a final decision.
Group 5: Mathematics
Students will choose one of two mathematics courses: Mathematics (Analysis and Approaches) or Mathematics (Applications and Interpretation). Both are offered at standard level and higher level. The right one depends on ability and what a student might like to study after school.
Group 6: The Arts
The creative subjects in Group 6 are Dance, Film, Music, Theatre, and Visual Arts. These are not just practical or performance-based courses. Students also look at creative work, reflect on their own practice and gain a greater understanding of their chosen art form.

Higher Level (HL) vs Standard Level (SL): What’s the Difference?
The two differ mainly in teaching time, workload, and depth. Let’s see how:
| Aspect | Higher Level (HL) | Standard Level (SL) |
| Depth of study | Covers the subject in greater depth | Covers a narrower scope |
| Recommended teaching time | 240 hours | 150 hours |
| Workload | It’s heavier and requires more detailed study | Manageable alongside other subjects |
| Number of subjects | Students usually take 3 HL subjects, though 4 may be allowed | Remaining subjects are taken at SL |
| Grading | Graded on a scale of 1 to 7 | Graded on a scale of 1 to 7 |
| University relevance | It is usually important for specialised courses such as medicine or engineering | It is relevant when the subject is not a key university requirement |
The DP Core: Theory of Knowledge, Extended Essay and CAS
Each IB Diploma student completes three core components along with six subjects. These are as follows:
Theory of Knowledge (TOK)
This program encourages students to question how knowledge is constructed and the role of evidence, perspective and interpretation in shaping what we accept as true.
Extended Essay (EE)
It is an independent research project that can be up to 4,000 words in length. Students choose a topic of inquiry, develop a research question and build an argument based on evidence.
Creativity, Activity, Service (CAS)
The program extends beyond academics through creative work, physical activity and service learning. The program involves students undertaking a range of experiences and reflecting on what they learn from them.
Can You Skip a Group 6 (Arts) Subject?
Absolutely. Group 6 is not mandatory for all students. If an arts subject does not fit their plans, students can choose another subject from languages, individuals and societies or sciences.
But that flexibility can be useful when university requirements are important. If you’re trying to get a degree in a science, for example, you might want to fill that slot with another science. It can also assist students to build up a suitable combination for their stronger subjects, as long as the school offers the course they want to take.

How to Choose the Right IB Diploma Programme subjects
When selecting the IB DP subjects, parents/students should consider three things: Your strengths, interests and study plans.
Choosing Based on Career and University Goals
Check early for university requirements. Some courses, e.g. medicine, engineering or economics, may require specific subjects, sometimes at a higher level.
Balancing HL and SL Subject Load
Keep the load realistic. Choose a higher level in the subjects that are most relevant to what you want to study in the future, and choose a standard level to make it an easier overall mix.
Recommended Subject Combinations for Popular Careers
The subject choices should align with the degree a student is considering and the entry requirements for the universities on their list. These combinations are a good place to start.
| Career Interest | Subjects to Consider |
| Medicine | Biology, Chemistry and Mathematics |
| Engineering | Mathematics, Physics and Chemistry |
| Business and Economics | Economics, Business Management and Mathematics |
| Computer Science | Computer Science, Mathematics and Physics |
| Humanities and Law | History, Global Politics, Economics or English |
| Art and Design | Visual Arts, Design Technology and a humanities subject |
Conclusion
Choosing the right IB Diploma Program subjects is more than obtaining marks. Students also need to think about what they like, what they are good at, and what might be needed in future courses.
