A-Levels vs IB: Which Qualification Is Right for Your Child?

As your child nears the end of their IGCSEs, the question of what comes next can feel daunting — particularly if you're weighing up A-Levels vs IB. Both are rigorous, globally respected qualifications that open doors to top universities. But they take fundamentally different approaches to learning, and the right choice depends on your child, not on which programme has better marketing.

This guide offers a genuine, balanced comparison. Richmond Online School delivers A-Levels rather than IB, and we'll explain why — but we'll also be upfront about where the IB has distinct strengths. The goal is to help you make an informed decision for your family.

What Are A-Levels?

A-Levels (Advanced Levels) are a two-year, subject-based qualification typically studied in Years 12 and 13 (ages 16–19). Students choose three to four subjects and study each in significant depth, building specialist knowledge that maps directly to university degree requirements.

A-Levels originated in the UK and are now offered in over 160 countries through exam boards such as Cambridge Assessment International Education (CAIE), Edexcel, and AQA. They remain the standard entry qualification for British universities and are widely accepted around the world.

Assessment is predominantly exam-based. Most subjects are assessed through externally set and externally marked examinations at the end of Year 13, with grades awarded from A* to E. Some subjects — particularly in the arts — may include a coursework or practical component, but the emphasis is firmly on final examinations.

The defining feature of A-Levels is depth through specialisation. A student aiming for engineering, for example, might study Mathematics, Further Mathematics, and Physics — dedicating substantial time to each, with roughly 10 hours of teaching per subject per week.

For a fuller overview of how A-Levels work, including subject choices and university pathways, see our A-Level Guide for Parents.

What Is the IB Diploma Programme?

The International Baccalaureate Diploma Programme (IBDP) is also a two-year pre-university qualification for students aged 16–19, offered at over 5,600 schools across 159 countries. Where A-Levels encourage depth, the IB is designed to develop breadth and balance.

IB students study six subjects drawn from different academic groups: Language and Literature, Language Acquisition, Individuals and Societies, Sciences, Mathematics, and the Arts (or an additional subject from the other groups). Three subjects are taken at Higher Level (HL) and three at Standard Level (SL).

Beyond the six subjects, IB students must complete three mandatory core components:

Theory of Knowledge (TOK): A course that explores how we acquire knowledge and encourages critical thinking across disciplines.

The Extended Essay (EE): A 4,000-word independent research project on a topic of the student's choosing — similar to a small university dissertation.

Creativity, Activity, Service (CAS): A requirement to engage in creative pursuits, physical activity, and community service throughout the programme.

The IB is graded on a points-based system. Each subject is scored from 1 to 7, with up to 3 bonus points available through TOK and the Extended Essay, giving a maximum score of 45 points. A minimum of 24 points is required to be awarded the diploma.

A-Levels vs IB: A Side-by-Side Comparison

Below is a structural comparison of A-Levels and the IB Diploma across the dimensions parents most often weigh up. Neither side is inherently better — it's a question of fit.

Number of subjects

• A-Levels: 3–4 subjects, chosen freely.
• IB Diploma: 6 subjects (3 Higher Level + 3 Standard Level) drawn from prescribed groups.

Approach

• A-Levels: Depth and specialisation in a small number of subjects.
• IB Diploma: Breadth and balance across multiple disciplines.

Core requirements

• A-Levels: None. The Extended Project Qualification (EPQ) is optional.
• IB Diploma: Theory of Knowledge (TOK), the Extended Essay, and CAS — all mandatory.

Assessment

• A-Levels: Primarily final exams (80–100% of the grade).
• IB Diploma: A mix of exams (~75%) and internal assessments (~25%).

Grading

• A-Levels: A* to E per subject.
• IB Diploma: 1 to 7 per subject, with up to 3 bonus points from TOK and the Extended Essay — a maximum total of 45.

Teaching hours per subject

• A-Levels: Roughly 10 hours of teaching per subject per week.
• IB Diploma: Roughly 5 hours per week at Higher Level and 3 hours at Standard Level.

Coursework burden

• A-Levels: Minimal in most subjects.
• IB Diploma: Significant — internal assessments, the Extended Essay, the TOK essay, and the CAS portfolio all run through the two years.

Flexibility of subject choice

• A-Levels: Complete freedom to combine any three or four subjects.
• IB Diploma: Must select one subject from each of the six prescribed groups.

Duration and global availability

• A-Levels: 2 years; offered in 160+ countries across more than 10,000 schools.
• IB Diploma: 2 years; offered in 159 countries across more than 5,600 schools.

UCAS tariff (maximum)

• A-Levels: 56 points per A* — three A*s equal 168 UCAS points.
• IB Diploma: A maximum score of 45 IB points equates to up to 720 UCAS points.

Depth vs Breadth: The Fundamental Difference

This is the single most important distinction, and it's worth sitting with before looking at anything else.

With A-Levels, your child picks three or four subjects and goes deep. They spend significantly more time per subject, cover more advanced material, and develop the kind of specialist expertise that university departments — particularly in the UK — value highly. A student studying A-Level Chemistry, for example, will cover content in greater depth than an IB Chemistry HL student, with more teaching hours devoted to that single subject.

The trade-off is that A-Level students don't study subjects outside their chosen area. A science-focused student may not touch a humanities subject or a second language for two years.

With the IB, your child studies across six subject groups, ensuring they maintain a broad academic foundation. Even a student passionate about physics will also study a language, a humanity, and contribute to the CAS programme. The IB explicitly values well-roundedness and intellectual curiosity across disciplines.

The trade-off is that breadth comes at the cost of some depth. With teaching time split across six subjects plus three core components, IB students cover less material per subject than their A-Level counterparts — though IB Higher Level courses are broadly comparable in rigour to A-Levels.

The honest question to ask: Does your child already know the general direction they want to pursue at university? If yes, A-Levels let them focus. If they're intellectually curious across many fields and don't want to narrow down yet, the IB is designed for that.

Workload and Time Management

Parents often ask which programme is harder. The truthful answer is that they're demanding in different ways.

A-Level workload is concentrated. With only three or four subjects, students can dedicate focused study blocks to each. The pressure builds towards final exams, which carry the bulk of the grade. Students who perform well under exam conditions and prefer sustained focus on fewer topics tend to thrive.

IB workload is distributed. Six subjects, plus the Extended Essay, TOK, and CAS, mean students are constantly juggling competing deadlines. Internal assessments (IAs) — which can include lab reports, oral presentations, written commentaries, and research projects — are due throughout the two years, not just at the end. The IB rewards students who are disciplined, well-organised, and comfortable managing multiple commitments simultaneously.

A practical consideration: the IB's CAS requirement — while valuable for personal development — adds time commitments outside of academic study. Your child will need to document their involvement in creative, physical, and service activities over the full two years.

If your child tends to be focused and prefers going deep on subjects they love, A-Levels may suit their working style. If they're naturally well-organised and energised by variety, the IB's structure can be motivating rather than overwhelming.

University Recognition: Do Admissions Teams Prefer One?

This is the question that keeps parents up at night — and the answer is reassuring. No top university in the world will reject your child because they studied A-Levels instead of IB, or vice versa.

Both qualifications are fully accepted by universities in the UK, the US, Europe, Australia, Canada, and beyond. Here's how it breaks down by region:

UK universities (including Russell Group and Oxbridge): A-Levels are the standard entry qualification. Universities publish offers in A-Level grades (e.g., A*AA for Medicine at Imperial). IB offers are published alongside, typically requiring 38–42 points for competitive courses. Both are treated equally in admissions.

US universities: The IB's holistic structure aligns well with the US admissions philosophy, which values breadth and extracurricular engagement. IB Higher Level scores of 6–7 can earn college credit, similar to AP exams. A-Levels are also accepted, though less familiar to some US admissions officers outside of internationally focused institutions.

Europe, Australia, and Asia: Both qualifications are well recognised. Singapore's national system is based on A-Levels, so local universities handle A-Level grades natively. Australian universities publish clear equivalency tables for both IB and A-Level results.

One data point worth noting: research published by the International Baccalaureate Organisation found that IB diploma holders were somewhat more likely to enrol at a Top 20 UK university than A-Level students. However, this may partly reflect the demographic profile of IB students (who are more likely to attend selective independent schools) rather than an admissions preference for the qualification itself.

The practical takeaway: choose the qualification that will help your child achieve the best grades and develop the skills they need — not the one you think universities prefer. Both work.

Which Type of Student Suits Each Programme?

Rather than asking which qualification is objectively better, it's more useful to consider which suits your child's personality, strengths, and ambitions.

A-Levels may suit your child if they:

• Already have a clear idea of what they want to study at university.
• Prefer going deep into subjects they're passionate about.
• Perform well in exam-based assessment.
• Want the flexibility to combine any subjects without restriction.
• Are aiming for a UK university with specific A-Level grade requirements.
• Don't want the additional time demands of CAS, TOK, and the Extended Essay.

The IB may suit your child if they:

• Enjoy studying across multiple disciplines and resist narrowing down.
• Are well organised and comfortable managing many concurrent deadlines.
• Value the research and critical thinking skills developed through TOK and the Extended Essay.
• Want a qualification that mirrors the breadth expected by US universities.
• Thrive on variety and find sustained focus on just three subjects limiting.
• Are interested in the personal development aspects of the CAS programme.

Neither profile is superior. They're simply different learning styles, and the right match produces better results — and a happier student.

Why Richmond Online School Offers A-Levels

At Richmond Online School, we deliver Cambridge International A-Levels rather than the IB Diploma. This is a deliberate choice, not a limitation, and there are specific reasons behind it.

Depth of specialisation. Our students and their families typically have a clear academic direction by the time they reach sixth form. A-Levels allow them to focus their time and energy on the subjects that matter most for their university applications and career goals.

Flexibility for diverse families. Many of our students are globally mobile, balancing studies with travel, sport, or other commitments. The A-Level structure — with fewer subjects and exam-focused assessment — is more adaptable to flexible schedules than the IB's continuous assessment model with CAS and IA deadlines throughout the year.

Proven outcomes. Richmond students studying A-Levels have received university offers from Cambridge, Imperial, UCL, LSE, Edinburgh, King's College London, Warwick, and others. The qualification delivers results.

Compatibility with online delivery. A-Levels' exam-focused structure works well in a live online teaching environment. Our small classes, expert UK teachers, and AI-powered tutoring provide the support students need without the logistical challenges that IB's CAS and practical components can present in a remote setting.

That said, if your child's learning style genuinely aligns with the IB — particularly the breadth requirement and the core components — we'd encourage you to explore IB schools as well. The right programme is the one that fits your child, and we'd rather you make the best decision for your family than the most convenient one for us.

Frequently Asked Questions

Is the IB harder than A-Levels?

They're challenging in different ways. The IB demands strong time management across six subjects, internal assessments, and the core components (TOK, Extended Essay, CAS). A-Levels require deeper mastery of fewer subjects, with grades heavily dependent on final exam performance. Which feels harder depends on your child's strengths — neither is objectively more difficult than the other.

Can my child switch from IB to A-Levels or vice versa?

Switching mid-programme is difficult because the curricula are structured differently. However, students who have completed IGCSEs (or the IB Middle Years Programme) can move into either A-Levels or the IB Diploma for their final two years. If your child has completed Cambridge IGCSEs, the transition to Cambridge A-Levels is particularly seamless.

Do UK universities prefer A-Levels over IB?

No. UK universities, including Oxford and Cambridge, accept both qualifications and publish entry requirements for each. Admissions decisions are based on predicted or achieved grades, the personal statement, and any additional assessments — not on which qualification system the student followed.

How many UCAS points is the IB worth compared to A-Levels?

An IB score of 45 (the maximum) converts to approximately 720 UCAS tariff points. Three A-Levels at A*A*A* equate to 168 UCAS points. However, most competitive universities make offers based on specific grades or points rather than UCAS tariff alone, so direct numerical comparisons can be misleading.

Can you study the IB online?

Some schools do offer the IB Diploma online, though the CAS requirement (which involves documented participation in creative, physical, and service activities) and internal assessment components can be more challenging to coordinate remotely. A-Levels are generally more straightforward to deliver in a fully online environment.

Making the Decision

The choice between A-Levels and the IB is not about which qualification looks better on paper — both are excellent. It's about which programme will bring out the best in your child over two demanding but formative years.

If your child values focus, already has a direction in mind, and performs best when they can dedicate their energy to subjects they love, A-Levels are likely the stronger fit. If they thrive on variety, enjoy research and independent projects, and want a structured path to becoming a well-rounded thinker, the IB has genuine appeal.

If you're still weighing options, our admissions team is happy to discuss your child's specific situation — with no pressure to enrol. You can also book a free trial class to experience how A-Level teaching works at Richmond Online School, and see whether the approach feels right for your family.
