AO4 — Critical evaluation
AO4 is the most demanding reading skill assessed at GCSE and is unique to OCR at this level. It asks you to evaluate how effectively a writer achieves their intended impact — to judge the writing, not just describe it. The typical question wording is: "A student says that [claim about the text]. To what extent do you agree?"
The difference between AO2 and AO4
| AO2 | AO4 |
|---|---|
| Analyse HOW techniques work | Judge HOW EFFECTIVELY they work |
| "The metaphor creates tension by…" | "This metaphor is particularly effective because… although a counter-reading might be that…" |
| Describe effect | Evaluate + defend + qualify |
AO4 responses that read like AO2 (analysis without judgement) are capped at band 3.
What "evaluate" means in practice
To evaluate is to:
- State a clear verdict ("strongly agree / partially agree / I would push back on this reading").
- Cite evidence from the text that supports the claim.
- Explain WHY the technique is (or isn't) effective — going beyond naming it.
- Qualify the verdict — acknowledge a counter-reading or limitation.
A one-sided "I fully agree" with no qualification will not reach the top band.
The AO4 paragraph structure
V–E–E–Q (Verdict → Evidence → Explanation → Qualification)
Verdict: I largely agree that the opening is effective at building suspense. Evidence: The short declarative "She did not look back." isolates the character's decision and refuses to explain it. Explanation: This is effective because the reader is placed in the same state of ignorance as the character — we do not know what she is walking away from, and the flat, unemotional verb "look" denies us the sentimental register we might expect at such a moment. Qualification: However, a reader might argue that the writer's refusal to elaborate is frustrating rather than intriguing — the effect depends on whether the reader has been given enough narrative context to trust the withholding.
Common AO4 mistakes
- All evaluation, no evidence. "This is very effective" repeated without quotation is subjective opinion, not literary evaluation.
- All analysis, no verdict. Writing AO2 paragraphs when asked to evaluate caps at band 3.
- Ignoring the qualification. "I agree because [three examples]" without nuance reads as simplistic.
- Treating "effective" as synonymous with "I liked it." Effective = achieves the writer's intended purpose for the implied reader. Personal taste is secondary.
Examiner language for top-band AO4

- "considers alternative responses and qualifies their verdict"
- "makes a sustained, perceptive judgement supported by precise quotation"
- "considers context and intended audience in forming their evaluation"

- Clear verdict stated in the first sentence?
- At least two pieces of specific evidence?
- Each piece of evidence followed by WHY it is/isn't effective?
- At least one counter-reading or qualification?
- Reference to the reader's likely experience of the technique?
Five ticks = top band.
