IB vs A Levels: A Simple Guide to Choosing the Right Path
Published 13 September 2026 · AI-assisted SchoolMatch Europe editorial · Sources and approach
The main difference is how you spread your studies. The full IB Diploma keeps a broad mix of subjects. A levels let you build a smaller set of separate subjects and study them in depth.
Neither route is the best choice for every child. Start with the subjects your child needs, the work they can manage, and the courses the school can actually teach. Then check the rules for the next step, such as a university course.
This guide explains the choice in plain English. Here, “IB” means the IB Diploma Programme, usually called the DP. It does not mean the IB programmes for younger children. The DP is for students aged 16–19. Source: IB Diploma Programme.
First, unpack the names
IB stands for International Baccalaureate. That is the name of the group behind several school programmes. The Diploma Programme is one of them.
A level means Advanced Level. An A level is a qualification in a subject, such as maths, history or chemistry. A qualification is the result or certificate you earn after a course and its required work.
Schools outside the UK may offer International A levels. Ask which exam board sets the course. Cambridge International is one example. Different boards and routes can have different course and exam rules.
Do not choose from the letters on a school brochure alone. Ask for the full programme name, the subjects on offer, and the year in which your child would start.
How the IB Diploma is put together
The full Diploma combines six subjects with three core parts. Students take subjects at higher level, called HL, and standard level, called SL. They take three or four at HL, with the rest at SL.
The subject groups cover languages, people and societies, science, maths and the arts. There is some choice within the rules. For example, a student may replace an arts subject with an extra subject from certain other groups. The exact mix needs to meet the Diploma rules. Source: IB curriculum.
The core adds three kinds of work:
- Theory of knowledge: thinking about how we know things and judge claims.
- Extended essay: a piece of research that leads to a paper of up to 4,000 words.
- Creativity, activity, service: taking part in creative work, physical activity and service.
These are part of the full Diploma, alongside the subjects. Source: IB core.
Before you picture the timetable, ask the school to show you one. A list of course names does not show when lessons happen or when major pieces of work are due.
How A levels are put together
With A levels, students choose separate subjects. A plan might include maths, physics and chemistry. Another might include history, English literature and a language. These are examples, not subject advice for a particular degree.
Cambridge International lets schools offer a wide choice of subject combinations. Yet one school will offer only part of the full list. A subject can also clash with another in the timetable. A large online list is not a promise that your child can take any mix. Source: Cambridge International curriculum.
Cambridge International A level courses usually take two years. AS level is a separate, shorter qualification and may form part of a staged route in some cases. Ask the school how its chosen subjects and exams work. Do not treat “AS” and “A level” as the same award. Source: Cambridge course length.
Compare the school day, not just the label
| Question | Full IB Diploma | A level route |
|---|---|---|
| What will I study? | Six subjects within set group rules, plus the core | A chosen set of separate subjects |
| How much choice do I have? | Choice within the Diploma rules and the school's offer | Choice within the school's offer, timetable and entry rules |
| Can I focus on one area? | You can give some subjects more depth at HL, while keeping breadth | You can build a more focused subject mix |
| What should I ask to see? | The six-subject plan, HL/SL choices and core timetable | The full subject plan, exam board and assessment plan |
| What can block my choice? | Missing subjects, unsuitable levels or a timetable clash | Missing subjects, entry rules or a timetable clash |
This table describes the shape of the routes. It does not tell you which course will feel easier to one child.
Start with the next step
If your child has an idea for a university course, work backwards from it. Open that course's own entry page. Write down the required subjects, levels, grades and any extra tests.
Check the entry year too. Rules for this year's applicants may change before your child applies.
Make a small table:
| Possible next step | Required subjects | Required level or grade | Who will confirm it? |
|---|---|---|---|
| Course or route one | To check | To check | The institution |
| Course or route two | To check | To check | The institution |
| Course or route three | To check | To check | The institution |
Do not use a broad claim such as “all top universities prefer IB.” A general claim cannot settle the rules of a named course. Do not assume that an A level is worth one fixed IB grade in every setting either.
If an entry page is unclear, ask the university and the school's adviser. Keep their replies. This is far safer than choosing subjects from a chart with no date or source.
What if your child has no career plan yet?
They do not need to invent one to start a useful talk.
Ask which subjects they enjoy enough to study when the work gets hard. Ask which ones they would miss if they had to stop. Then ask which subjects they find hard but still want to keep.
A broad course can suit a child who wants to stay with several fields. A focused course can suit a child who wants more time in a few fields. These are reasons to explore each route, not rules that sort children into fixed types.
It also helps to separate “I dislike this subject” from “I dislike how this subject is taught now.” A chat with a teacher and a look at real work from the next course can make that difference clearer.
There is no useful shortcut called “the easy option”
A child might find six subjects and the core hard to balance. Another might find a deep course in three subjects harder than a wider mix.
Ask about the work your child would face in a normal week. How much reading is there? Which tasks need long written answers? When do projects and exams overlap? What happens if a pupil falls behind?
Ask to see a sample task from each subject. Reading the title “chemistry” is not the same as seeing what a chemistry student must do.
Then talk about the whole week. Include sleep, travel, sport, clubs and time with friends. A plan that only works when every evening is full is worth looking at again.
Three made-up students, three useful questions
These examples are fictional. They show ways to think, not predictions about real pupils.
Maya likes several subjects
Maya enjoys maths, languages, art and history. She is not ready to drop most of them. The IB Diploma is worth a close look because it keeps a broad mix.
Her next question should be: “Can this school offer the mix I want, and can I manage the core work too?” Liking many subjects does not make every six-subject plan a good fit.
Leo wants to focus on science
Leo enjoys maths and science and is keen to spend more time on them. An A level route may fit that wish.
His next question should be: “Does this exact set meet the entry rules for the courses I may want?” Choosing only favourite subjects can close a door if a required subject is missing.
Sara may move again
Sara's family may leave the country halfway through the course. Her first task is to ask both schools about a possible transfer.
The next school may teach different topics, use a different board or have no space in a needed class. A familiar programme name does not make a mid-course move simple. Sara needs a transfer plan, not a promise based on the label.
The school's actual offer matters
A route can look perfect on paper and still be a poor fit at a particular school. Ask about the staff who teach your child's subjects. Ask how pupils get help and who tracks work across the week.
For the IB Diploma, ask who helps pupils plan the core tasks. For A levels, ask who checks that the chosen mix keeps the right future options open.
Ask what happens if too few pupils choose a subject. Is the class certain to run? Could it move online? Would there be an extra charge? If the school cannot yet confirm it, mark that as an open question.
You can check a school's IB programme listing in the IB World School finder. Look for the right programme. A listing for a younger-age IB programme does not answer your question about the Diploma.
Let your child do part of the comparing
Give your child the timetable and sample tasks. Ask them to mark three things:
- Work they would be glad to do.
- Work they expect to find hard.
- Work they do not yet understand.
Talk through the third group first. A choice made from fear of an unknown term is not much of a choice.
Then ask: “Which plan would you still choose on a hard Tuesday?” That question brings the talk back to real lessons and work. It is often more useful than asking which badge sounds more impressive.
Questions to take to the school
Bring your draft subject plan and ask:
- Can my child take this exact mix at this campus?
- What are the entry requirements for each subject?
- Which classes are confirmed to run?
- How do you spread large tasks across the year?
- What support is available if a child struggles?
- How does a pupil change a subject, and by when?
- Who checks the fit with future course requirements?
- What are the full course and exam costs?
Write the answers beside the subject plan. That turns an open-day talk into something you can compare later.
Make the choice in this order
First, remove any plan that misses a required subject or an essential support need. Next, check which plan your child understands and wants to follow. Then compare the real teaching, timetable, cost and trip to school.
Do not expect one programme to do all the work for your child. The route is the frame. The day-to-day teaching, the subject mix and your child's effort fill it.
Use SchoolMatch Europe's directory to find possible schools. Then ask each school to confirm the exact programme, subject choices and places for your child's start year.
