Cambridge IGCSE Global Perspectives: The Written Exam (0457)

This guide covers Component 1 Written Exam, one of three components in Cambridge IGCSE Global Perspectives (0457), for examination 2025-2027. This syllabus is unusual among IGCSE subjects: the specification explicitly states that knowledge of content is not assessed. Instead, candidates develop transferable skills of research, analysis, evaluation, reflection, communication and collaboration using an open list of global-issue topics as a stimulus.

Where this fits in 0457

All candidates take Component 1 alongside Component 2 (Individual Report) and Component 3 (Team Project). Component 1 is externally set and marked by Cambridge, while Components 2 and 3 are coursework-style tasks completed over the course. Teachers and students choose topics from a list of 22 broad global issues (such as Climate change, energy and resources or Migration and urbanisation) to explore across all three components.

Syllabus coverage

CAMBRIDGE IGCSE GLOBAL PERSPECTIVES (0457) — COMPONENT 1 WRITTEN EXAM

Component 1 is a 1 hour 25 minute written paper worth 70 marks, externally set and marked by Cambridge International. It contains four compulsory questions based on source documents provided with the question paper, covering a global issue related to one of the topics on the topic list. Sources provide background information and different perspectives on the chosen issue and may include images and material from a variety of subject backgrounds and media.

How to approach it

Because Component 1 is entirely source-based rather than testing memorised content, practising close, careful reading of unfamiliar source material under timed conditions is the single most useful preparation – work through past papers focused on extracting perspectives and evidence from sources you have never seen before, not on revising facts about specific topics. Since the exam explicitly tests skills like identifying different perspectives and evaluating evidence, practise naming whose perspective a source represents and what evidence supports it, rather than simply summarising what a source says. Reading time is built into the paper’s overall time allowance, so practise budgeting time to read all sources thoroughly before starting to write.

What the written paper actually tests

Global Perspectives is assessed on skills, not on remembered content. The paper supplies unseen source material and asks you to work with it. The skills are usually grouped as research, analysis, evaluation, reflection and communication — and the marks follow the skill, not the topic.

That has a practical consequence: revising “facts about climate change” is largely wasted effort. Practising the moves — identifying a perspective, testing evidence, weighing a source — is what raises the grade.

Perspectives, arguments and evidence

A perspective is a point of view supported by reasoning and evidence, held for reasons connected to the holder’s context — national, cultural, economic, generational, professional. It is not simply an opinion.

Every issue should be considered at three levels: personal, national and global. A strong answer moves between them rather than staying at one.

Distinguish carefully:

• Argument — a conclusion supported by reasons.
• Evidence — data, examples or testimony offered in support.
• Assertion — a claim with no support at all.
• Assumption — something taken for granted but unstated.

Analysing and evaluating sources

Analysis identifies what a source claims, what reasons it offers, and what it assumes. Evaluation judges how good it is, using criteria you should be able to name and apply:

Criterion	Question to ask
Credibility	Who wrote it, and what expertise do they have?
Bias	Do they gain from this view? Is the language loaded?
Currency	Is it recent enough for the claim?
Relevance	Does it actually address the question?
Corroboration	Do independent sources agree?
Sample and method	Where data is used, how was it gathered?

The common weakness is asserting bias rather than demonstrating it. “This source is biased because it is from an oil company” is weaker than quoting the loaded phrasing and explaining the interest served.

Constructing a response

A strong extended answer states a clear line of reasoning, uses source material as evidence rather than summarising it, considers at least one counter-argument genuinely, and reaches a justified conclusion that follows from what came before.

Reflection — what you now think and why your view changed — carries marks and is routinely skipped.

Worked example

A source states: “A survey of 200 people in one city found 78% support the new transport policy, so the country clearly backs it.”

Claim       -> the country supports the policy
Evidence    -> a survey, 78% of 200 people
Assumption  -> one city represents the whole country

Evaluation:
  Sample size 200 is small for a national claim
  Sample is geographically narrow -- urban only, one city
  "Clearly" overstates what the data can support
  No information on who conducted it or how respondents were selected

Naming the specific weakness beats a general comment about reliability.

Common mistakes

Revising topic content instead of practising skills. Summarising a source rather than using it as evidence. Asserting bias without demonstrating it from the text. Treating an assertion as evidence. Ignoring the personal, national and global levels. Omitting reflection. Presenting a counter-argument then not responding to it.

Quick revision checklist

• Define perspective, argument, evidence, assertion and assumption, and tell them apart in a source.
• Consider any issue at personal, national and global levels.
• Apply all six evaluation criteria and demonstrate a weakness from the text.
• Build an argument with a clear line of reasoning and a genuine counter-argument.
• Write a reflection that explains how and why your view developed.
