Ask a parent which exam board their child follows and many will say "GCSE" or "A-Level" — the qualification name, not the board. Ask which board and the answer is often a guess. This confusion is understandable. To families who are new to the UK or international school system, the distinction between CAIE, Edexcel and AQA can appear administrative rather than substantive.
It is not. The differences between examination boards are real, specific and consequential for how students prepare — and therefore for what a tutor actually needs to know.
This article sets out the key differences between the three major boards, explains why board-matching matters in tutoring, and offers practical guidance on verifying a tutor's board-specific expertise.
Three Boards, Three Different Examinations
Cambridge Assessment International Education (CAIE)
CAIE, part of Cambridge University Press & Assessment, offers the Cambridge IGCSE and Cambridge International A-Level qualifications. These are the dominant boards in British international schools outside the UK, and are widely recognised by universities in the UK, US, and globally.
CAIE examinations use a distinctive set of command terms — "state", "describe", "explain", "deduce", "suggest", "evaluate" — each mapped to a precise type of expected response. Mark schemes are structured around these terms, and a student who writes an evaluative response where only a description was required will not receive credit for what they have written, regardless of its quality.
CAIE papers are also structured differently from UK domestic boards. Many CAIE sciences use a multiple-paper format with separate theory, practical, and alternative-to-practical papers. Some subjects include coursework components. The mark allocations and the balance between paper types affect the weighting of different skills.
Pearson Edexcel
Edexcel, offered by Pearson, provides IGCSE qualifications widely used in UK independent schools and a growing number of international schools, alongside its A-Level suite. The Edexcel IGCSE and the Cambridge IGCSE are sometimes treated as interchangeable by families. They are not. The specifications differ by topic, by the sequence in which content is covered, and by the style of questioning in the examination papers.
Edexcel A-Levels are modular in structure across some subjects and linear in others. The command terms and mark-scheme language differ from CAIE in ways that are not always obvious until a student sits a past paper from the wrong board. Edexcel mathematics, for instance, uses a notation and formula booklet approach that differs from CAIE's equivalent.
AQA
AQA (Assessment and Qualifications Alliance) is the most widely used board within UK state and independent schools for GCSEs and A-Levels. It does not offer an IGCSE qualification — families whose children sit AQA examinations are in the UK domestic system. AQA's mark schemes, question types, and assessment objectives reflect the reformed GCSE and A-Level specifications introduced in 2017, and these differ meaningfully from Edexcel and CAIE in how marks are allocated and how extended-response questions are assessed.
For families in the UK domestic school sector, AQA subjects are commonly paired with school-based coursework or non-exam assessment (NEA) components. A tutor working with an AQA student who does not understand the NEA requirements for that subject will miss a significant portion of the assessed content.

Why the Board Must Match the Tutor
The practical consequence of board mismatch is straightforward: a student practises the wrong type of response, uses the wrong vocabulary, and prepares for a paper that does not look like the one they will actually sit.
Consider a student preparing for CAIE A-Level Biology who works with a tutor whose primary experience is AQA A-Level Biology. The topics overlap significantly, but the assessment objectives differ. A CAIE paper places considerable weight on application and data analysis in a specific format. An AQA-experienced tutor will prepare the student well in content knowledge but may miss the particular way CAIE structures its extended-answer mark schemes — where, for example, a six-mark "evaluate" question requires a very different response structure from what AQA would expect.
This is not a criticism of any board or any tutor. It is a structural reality: each board is a system with internal logic, and teaching effectively within that system requires familiarity with its specifics.
The Education Endowment Foundation's research on high-quality tutoring emphasises that the most effective one-to-one sessions are tightly aligned to the learner's specific curriculum goals. Board specialism is one of the mechanisms by which that alignment is achieved in practice.
As discussed in our article on one-to-one tuition, diagnostic precision — knowing exactly what the student is being asked to do in their examination — is foundational to effective tutoring. Board knowledge is part of that diagnostic precision.
How to Verify a Tutor's Board Knowledge
Many tutors describe themselves as specialists in a subject without specifying which board. These questions help establish genuine board expertise:
Which syllabus code do you teach? Every board publishes its specifications with a code (e.g., CAIE A-Level Mathematics 9709, Edexcel A-Level Mathematics 9MA0). A tutor who knows the board will know this.
How does the mark scheme handle [a specific question type]? For example, how does CAIE mark a six-mark "evaluate" question in A-Level Biology? A tutor who has marked or taught to that board will describe the mark-point structure accurately.
Can you show me an example past paper question from the relevant board? Familiarity with the paper's aesthetic — the question style, the command term usage, the mark allocation per question — is a practical indicator of board experience.
Have you used the board's examiner report? CAIE, Edexcel and AQA all publish examiner reports after each examination session, identifying common errors and what distinguishes high-scoring from mid-scoring responses. Tutors who use these reports are board-literate in a meaningful way.
At Sophyra, tutors are matched to students by board and specification as a standard part of the process. Our science and mathematics tutors each work within specific board specialisms rather than across all boards generically.
When Switching Boards Mid-Course Is a Problem
Some families, particularly those relocating between countries or transferring between schools, find that their child has begun a course under one board and needs to switch to another. This situation carries specific risks.
The content overlap between boards at IGCSE is substantial for core subjects, which can give a false impression that the transition is straightforward. In reality, the differences in command terms, mark-scheme conventions, and paper structure mean that a student who has been preparing for CAIE may need dedicated work on adapting their response technique to the new board's requirements — even when the content is familiar.
The reverse applies when a student has begun an Edexcel A-Level and then transfers to a school using CAIE. The assessment objectives, the formula booklet (or lack of it), and the paper structure are sufficiently different that content knowledge alone does not guarantee performance.
This is also relevant for students at international schools who are preparing for university applications using A-Level or IGCSE grades. The board documented on the certificate is the one universities will see, and it needs to be the board the student has genuinely prepared for.
Our article on consolidation of practice and long-term mastery addresses how students can consolidate learning across a syllabus — which is particularly important when a board transition has created gaps in coverage.
How Sophyra Matches by Board
At Sophyra, the initial consultation specifically identifies the examination board, the specification year, and the subject combination before any tutor is recommended. This is not a formality — it shapes every aspect of the tutoring programme.
Where a student is preparing for CAIE IGCSE or A-Level, their tutor will have taught or tutored within that specific system and will be familiar with the paper structure, command term requirements, and mark-scheme logic. The same applies to Edexcel and AQA students. If a student is preparing for multiple boards simultaneously — for example, a student in a school that uses both Edexcel and CAIE across different subjects — each subject is matched separately.

Frequently Asked Questions
Does it really matter which exam board a tutor has experience with? Yes. Each board has a distinct paper structure, command term vocabulary, and mark-scheme logic. A tutor without board-specific experience may teach the content correctly but prepare a student for the wrong type of examination response.
Is the Cambridge IGCSE the same as the Edexcel IGCSE? No. While both are called IGCSE, the specifications, topic coverage, and examination paper styles differ by board. A student following CAIE IGCSE Chemistry is sitting different papers, with different assessment objectives, from a student following Edexcel IGCSE Chemistry.
Does AQA offer an IGCSE? No. AQA offers GCSE qualifications within the UK domestic system. Families whose children sit AQA examinations are in UK schools; AQA is not offered by international schools. If your child's school is outside the UK, they are almost certainly on CAIE or Edexcel.
What if my child's school is changing exam boards? This is more common than many expect, particularly in schools that are transitioning curricula. Contact Sophyra for a consultation — we can identify where the gaps are between the two boards' specifications and prioritise the content and technique areas that need additional attention.
How do I find out which board my child is on? Ask the school directly for the full specification name and code. This information should also be on any past papers the student has been given for homework or mock examinations.
