The Claim, Evidence, Interpretation Model
A three-part structure—claim, evidence, interpretation—that turns loose observations into rigorous, mark-scheme-aligned analytical arguments.
Every strong piece of analytical writing—whether in Paper 1, Paper 2, the HL Essay, or the Individual Oral—is built from the same three-part unit. Master this unit and you can generate rigorous analysis on command, sentence after sentence.
- Claim (Thesis): A focused statement about what a writer is doing or why a text element matters.
- Evidence (Quote): A specific piece of text—a quotation, word, or phrase—that supports your claim.
- Interpretation (Effect): Your explanation of how that evidence creates meaning, shapes tone, or influences the reader.
Think of it as a chain: you assert something, you prove it with the text, and then you explain why it matters. Skip any link and the argument collapses—either into unsupported opinion (claim with no evidence) or into mere quotation-dropping (evidence with no interpretation).
Summary vs. analysis — the quickest self-check: If your sentence starts with "The character is…" or "The poem is about…", you are summarizing. Rewrite it as "The character's broken syntax in line 4 suggests…". Markers reward active, interpretive verbs (suggests, implies, highlights, underscores) over passive, descriptive ones (is, are, shows).
Notice how each part does a distinct job. The claim tells the marker what to look for; the evidence proves it's really there; the interpretation explains why it matters. In exam writing, you don't need to literally write the labels "Claim:", "Evidence:", "Interpretation:"—but you should move through them in that order, every time, so the logic is visible even without the scaffolding words.
A compact way to internalise this is the formula Claim + Technique + Effect, which folds the model into a single sentence:
- Claim: what you observe ("The author employs…")
- Technique: the precise device at work (diction, alliteration, imperative mood, syntax)
- Effect: the impact on meaning or reader (creates urgency, suggests isolation, destabilises tone)
This formula works because it forces you to name the device, keeps your explanation anchored to how the text works rather than what it's about, and translates directly into mark-scheme language: identification, analysis, and commentary are exactly what examiners are trained to reward.
The model also clarifies overlapping terms that trip students up in exams: tone (the writer's attitude, evidenced through diction or syntax), mood (the reader's emotional response, evidenced through imagery or setting), and atmosphere (the combined feeling created when tone and mood work together with setting). Applying Claim + Technique + Effect to these terms keeps the analysis precise instead of impressionistic—for example: Claim – "The recurring adjective 'damp'"; Technique – diction; Effect – "evokes not only physical discomfort but also an undercurrent of decay that permeates the entire narrative."
- State the claim: identify the specific textual feature and what the writer appears to be doing with it.
- Present the evidence: quote the exact word, phrase, or line that demonstrates the claim.
- Name the technique precisely (diction, syntax, imagery, structure, etc.) if not already implied by the claim.
- Interpret the effect: explain how this evidence shapes meaning, tone, or reader response, and link it outward to a larger pattern (characterisation, theme, climax, or global issue).
- Repeat the cycle for the next piece of evidence, ensuring each paragraph builds cumulatively toward the overall argument rather than restating the same point.
Exam tip: In timed writing, silently label your sentences C-E-I as you draft (even if you don't write the labels down). If you can't identify which part you're currently writing, you've probably drifted into summary or unsupported assertion.
- Claim = what the writer is doing / why it matters; Evidence = the exact quote/word/phrase; Interpretation = how it creates meaning or effect.
- Formula shortcut: Claim + Technique + Effect — always name the device explicitly.
- Summary describes 'what happens'; analysis argues 'why it matters' — swap passive verbs (is/are) for active ones (suggests/implies/underscores).
- Tone = writer's attitude (diction/syntax); Mood = reader's emotional response (imagery/setting); Atmosphere = tone + mood + setting combined.
- Move through claim, evidence, interpretation in that order every time to make your argument's logic visible to the marker.
