How CAIE and Pearson Edexcel International Mark Schemes Work

Same underlying principle, slightly different conventions

CAIE (Cambridge International) and Pearson Edexcel International use the same broad marking logic as their UK domestic equivalents. You're either credited point by point against a list of acceptable answers, or placed in a band based on the overall quality of an extended response. But the labelling and structure differ enough from AQA/Edexcel UK GCSE conventions that it's worth understanding on its own terms, not assuming it works identically.

Point-marked questions

Short-answer, multiple-choice and structured questions are marked against a list of acceptable points, often phrased as alternatives separated by "or" in the mark scheme. Credit goes to any listed acceptable phrasing, not just the exact wording shown. Method marks are available on calculation questions the same way they are on domestic boards: showing your working earns credit even where the final answer is wrong.

Levels-of-response questions on extended answers

Longer questions, essays on English Literature or History, extended responses on Economics or Business, are placed into a level or band based on overall quality. That's similar in spirit to the levels-of-response system used by AQA, Edexcel and OCR domestically (see our general guide to how mark schemes work), but with band descriptors specific to the CAIE or Pearson International syllabus rather than the UK domestic one. Always check your own syllabus's actual band descriptors. Don't assume they read identically to a UK GCSE mark scheme just because the structure looks similar.

Indicative content isn't a checklist

Both CAIE and Pearson Edexcel International publish "indicative content" alongside mark schemes: example points a strong answer might include. As with UK boards, this is guidance for examiners, not a list you need to match exactly. A valid, well-explained point that isn't on the list still gets credited if it answers the question.

Where the two providers diverge most

• CAIE often splits a subject across Core and Extended tiers at IGCSE, or AS-then-A2 papers at International A-Level, with separate mark schemes per tier or stage.
• Pearson Edexcel International tends to use a more unified, single-tier structure per subject, with its own unit-based mark schemes for each modular paper.

If you're studying both an IGCSE and an International A-Level subject, don't assume the mark scheme conventions transfer automatically between them just because the subject name is the same.

Revising with ExamPass.ai

Every exam paper generated on ExamPass.ai for IGCSE, International A-Level or International AS-Level comes with a mark scheme written to match your specific board's actual conventions, and instant marking applies it directly. The feedback you get reflects how CAIE or Pearson Edexcel International would genuinely mark it, not a generic UK domestic equivalent.
