IGCSE vs. A-Levels vs. IB: Which Curriculum is Right for You?
Choosing the right curriculum in high school can feel like trying to find your way through a maze. There are pros, cons and expectations for each path. If you want to go to the best universities in the world or are a parent trying to figure out the best academic path for your child, it’s important to know the differences between IGCSE, A-Levels and the IB Diploma. The right choice can affect what your child wants to study, what colleges they can go to and even what jobs they can get.
IGCSE (International General Certificate of Secondary Education)
IGCSE is a test that students aged 14 to 16 take. It is offered by many exam boards and is accepted all over the world. It focuses on knowledge in specific subjects and lets students choose from a wide range of subjects. This curriculum helps students build strong basic skills in important subjects like math, science, languages and the humanities.
Most of the time, tests are used to grade students, but some subjects may also have homework. It gets students ready for higher education and is often the first step towards A-Levels or IB.
A-Levels (Advanced Level Qualifications)
People usually take A-Levels when they are between the ages of 16 and 18, mostly in the UK and Commonwealth countries. Most students pick three to four subjects based on what they’re good at in school and what they want to do in college.
This curriculum is great for students who know what they want to study. Someone who wants to be an engineer might study math, physics and chemistry, for example. A-Levels let students learn a lot about a subject, and having a lot of knowledge can help them get into specialised university programs.
IB (International Baccalaureate)
People know the IB for its holistic approach. Students must take six classes, one from each subject area and also finish three core components: Theory of Knowledge (TOK), Extended Essay (EE) and Creativity, Activity, Service (CAS).
IB students should learn how to think critically, do research and be aware of what’s going on in the world. This program is very well-respected by colleges and universities all over the world, but it requires good time management and a strong work ethic.
A Quick Look at the Main Differences
- Specialisation vs. Breadth: A-Levels encourage people to focus on one area. IB requires a lot of breadth and depth. IGCSE gets you ready for both.
- Assessment Style: A-Levels and IGCSE rely a lot on final exams to test students. IB has essays, presentations and other schoolwork.
- University Recognition: All three are accepted around the world. A-Levels are better for courses that are specific to a subject. IB is better for programs in the arts or that combine different fields.
