What is actually assessed

Skills, not content. Revising facts about a topic is largely wasted; practising the analytical moves is what raises the grade.

The moves: identify perspectives · analyse arguments · evaluate evidence · construct your own reasoning. (Reflection is not one of the moves credited in this paper – see below.)

The paper’s structure

Component 1: Written Exam
  1 hour 25 minutes, 70 marks
  FOUR compulsory questions, based on SOURCE documents
  Externally set and marked by Cambridge

Sources: background info + different perspectives on ONE global issue
         may include images and material from varied subject backgrounds

Component 1 sits alongside Component 2 (Individual Report) and Component 3 (Team Project), both coursework-style tasks. All three draw on the same list of broad global-issue topics (such as Climate change, energy and resources, or Migration and urbanisation), but Component 1 alone is the externally-marked written paper. Reading time is built into the overall time allowance, so budgeting time to read every source thoroughly before writing is part of the skill being tested, not a bonus.

The vocabulary — get these precise

Term Meaning
Perspective A viewpoint supported by reasons and evidence, held for reasons linked to context
Argument A conclusion supported by reasons
Evidence Data, examples or testimony offered in support
Assertion A claim with no support
Assumption Something taken for granted but left unstated

A perspective is not just an opinion — it has reasoning behind it.

0457’s own syllabus names eight terms candidates will benefit from understanding specifically for the Written Exam. Four of them – bias, claim, fact and opinion – already come up throughout this guide and the practice questions. The other four are easy to miss, so learn them explicitly:

Term Meaning
Generalisation A broad conclusion drawn from a limited number of cases, which may not hold true more widely
Prediction A statement about what is expected to happen in future, based on current evidence or trends – distinct from a fact, which can already be checked
Value An underlying belief about what matters or what is right, which shapes why someone holds a particular perspective
Vested interest A personal or financial stake in a particular outcome, which can motivate a one-sided view of an issue

(9239, the A-Level sibling qualification, names a wider and different set of terms for its own written paper – don’t mix the two lists.)

The three levels

Always consider an issue at personal, local and/or national, and global level. Moving between them is a marker of a strong answer.

Evaluating a source — six criteria

Criterion Ask
Credibility Who wrote it? What expertise?
Bias Do they gain from this view? Loaded language?
Currency Recent enough for the claim?
Relevance Does it address the question?
Corroboration Do independent sources agree?
Method Sample size? How was data gathered?

Demonstrate bias by quoting the loaded wording — don’t merely assert it.

Worked example — spotting the hidden assumption

A source states: “Renewable energy investment tripled over the last decade, proving that governments now prioritise fighting climate change above all else.”

Claim       -> governments now prioritise climate change above
               all else
Evidence    -> renewable energy investment tripled

Hidden ASSUMPTION -> increased investment in one area means it is now
                      the TOP priority, ranked above every other goal

Evaluation:
  The evidence (tripled investment) supports a narrower claim -- that
  climate change is being taken more seriously -- but does not, on its
  own, support the much stronger claim that it now outranks every
  other government priority
  No baseline given -- "tripled" from what starting figure?
  No comparison with spending on other priorities is offered

The gap between what the evidence actually shows and what the source claims it shows is exactly what “identifying an assumption” means in practice — the evidence can be entirely accurate while the conclusion drawn from it still overreaches.

Statistics — always interrogate

  • What is the sample size and how was it selected?
  • Is the sample representative of the claim being made?
  • Is the baseline given? (“Doubled” from 2 to 4 is nearly meaningless.)
  • Is the comparison fair?

Structuring an extended answer

  1. A clear line of reasoning.
  2. Source material used as evidence, not summarised.
  3. A counter-argument genuinely considered and responded to.
  4. A conclusion that follows from the reasoning.

Note: reflection is not part of this list. The Written Exam’s own AO2 (Reflection) weighting is 0% – unlike the Individual Report and Team Project, where reflecting on how and why your view changed genuinely does carry marks.

Exam traps

  • Summarising a source instead of using it.
  • Asserting bias without evidence from the text.
  • Treating an assertion as evidence.
  • Presenting a counter-argument then ignoring it.
  • Staying at one level (usually global) and never reaching personal or local/national.

Self-test

  1. Distinguish an argument from an assertion.
  2. A source says “a survey of 150 people in one town shows the nation supports the policy.” Give two weaknesses.
  3. What are the three levels at which issues should be considered?
  4. How should you demonstrate that a source is biased?
  5. Is reflection credited in the Written Exam?

Answers: 1. An argument offers a conclusion supported by reasons; an assertion is a bare claim with no support. 2. The sample is small and geographically narrow (one town), so it cannot support a national claim; no information on how respondents were selected, so it may not be representative. 3. Personal, local and/or national, global. 4. Quote the loaded or one-sided wording and explain whose interest that phrasing serves. 5. No – the Written Exam’s AO2 weighting is 0%; reflection is credited in the Individual Report and Team Project instead.

  1. How long is Component 1 and how many marks is it worth?
  2. What is a hidden assumption, and how does it differ from stated evidence?

Answers (continued): 6. 1 hour 25 minutes, 70 marks, with four compulsory questions based on source documents. 7. A hidden assumption is an unstated step a source’s conclusion relies on without justifying — unlike stated evidence, which is given directly, an assumption has to be inferred by the reader, and a strong answer makes it explicit before evaluating whether it is reasonable.
