IB Paragraph Writing Techniques | How to Use PEEL & TEEL Across Subjects
Solid arguments can still lose marks if your paragraph structure breaks down. Learning when to use PEEL versus TEEL—and how to adapt each to different IB subjects—can sharpen the impact of every paragraph you write.
PEEL vs. TEEL: Which Framework Should You Use, and When?
The short answer: PEEL (Point → Evidence → Explanation → Link) works well as a default across most IB essay-based subjects, while TEEL (Topic sentence → Evidence → Explanation → Link) is essentially the same architecture with a slightly different label for the opening move. A meaningful distinction emerges when you encounter subject contexts where interpreting data before explaining its significance matters—at that point, keeping the Evidence step deliberate and unhurried becomes critical. Either way, the underlying logic is identical: make a claim, back it up, analyze it, and connect it forward.
Rather than debating acronyms, the more useful question is: how do I adapt this core structure to each subject's specific demands? That is what this article addresses.
What Is PEEL, and Why Does It Work Across IB Subjects?
PEEL breaks a paragraph into four functional moves:
| Step | Role | Question it answers |
|---|---|---|
| Point | Your mini-argument or claim | "What am I arguing in this paragraph?" |
| Evidence | Specific support (quote, data, example) | "What shows this is true?" |
| Explanation | Analysis that connects evidence to the point | "Why does this evidence support my claim?" |
| Link | Transition that ties back to the essay thesis or forward to the next paragraph | "How does this fit the bigger picture?" |
The reason this four-part rhythm travels well across the IB is that every essay-based assessment, regardless of subject, is asking students to do the same thing: argue a position and justify it with subject-specific evidence. Whether you are writing about a poet's use of ambiguity in English A, a historian's interpretation of a primary source, or an economist's reading of a demand curve, the cognitive move is structurally the same.
How Does TEEL Differ, and When Should You Prefer It?
TEEL (Topic sentence → Evidence → Explanation → Link) places "Topic sentence" where PEEL places "Point." In practice, these are the same move: you open the paragraph with a sentence that carries a specific, arguable claim—not a vague statement of topic. The acronym difference is mostly pedagogical convention.
Where TEEL does create useful emphasis is in subjects where the distinction between presenting evidence and explaining evidence benefits from being made very explicit—particularly in science reports, data-based questions, and research writing. When you are describing what a graph shows before you explain what it means, the Evidence → Explanation order becomes a two-step analytical discipline rather than a single blurred move.
| Context | Recommended emphasis | Why |
|---|---|---|
| English A essay | PEEL | Close textual analysis privileges the argument first, then quotation |
| History essay | PEEL | Historical claims must be made before sources are deployed |
| Biology/Chemistry data analysis | TEEL / explicit E→E split | Describing observations before interpreting them reflects scientific method |
| Economics commentary | PEEL with diagram integration | Argument drives diagram use, not the reverse |
| TOK essay | PEEL with knowledge claim framing | Every paragraph should open with a knowledge claim |

How Do You Apply PEEL in Practice? A Step-by-Step Breakdown
Below is a worked example in a History context, annotated by step.
Essay question (example): To what extent was propaganda the most significant factor in consolidating the regime's power?
Point:
Propaganda was central to the regime's consolidation of power, particularly in shaping public perception during the early phase of rule.
One sentence. One arguable claim. No evidence yet.
Evidence:
State-controlled media systematically suppressed dissenting voices while amplifying official narratives through controlled broadcasts and print.
Specific and concrete—ideally referencing a named source, document, or historian in your actual essay.
Explanation:
This demonstrates that propaganda functioned not merely as information management but as a structural mechanism of control: by limiting the population's access to alternative viewpoints, the regime reduced the cognitive space in which opposition could form.
This is where you move from "what happened" to "what it means for the argument."
Link:
However, propaganda alone cannot account for the regime's durability; its effectiveness depended on parallel instruments of coercion, which the following paragraph examines.
The link keeps your essay argumentative rather than descriptive, and signals the overall structure to the reader.
How Should You Adapt the Evidence Step to Different IB Subjects?
The "E" in PEEL/TEEL means very different things depending on subject and task type. Getting this adaptation right is one of the highest-leverage writing skills in the IB.
| Subject | What counts as strong Evidence |
|---|---|
| English A (Literature/Language) | Direct quotations with line or page reference; specific stylistic features |
| History | Primary source references; named historians and their interpretations |
| Biology / Chemistry | Quantitative data from experiments; named studies or published findings |
| Economics | Real-world examples; data from named sources (e.g., central bank reports) |
| TOK | Knowledge examples drawn from Areas of Knowledge; Named real-life situations |
| Extended Essay | Depends on subject; often a mix of primary and secondary sources |
For science subjects, the evidence step often splits into two sub-steps: observation (what the data shows) and interpretation (what it means). This is where the TEEL framing helps students resist jumping to conclusions before describing results accurately.
For writing conventions in lab report contexts, the IB Biology HL guide and IB Chemistry HL guide go deeper on how evidence is expected to be presented and analyzed.
How Do You Use PEEL in Extended Paragraphs and Multi-Paragraph Arguments?
For complex essay questions—particularly in Paper 2 responses, Internal Assessments, or the Extended Essay—single-layer PEEL paragraphs are rarely enough. You will often need to:
1. Stack Evidence within a single PEEL paragraph Use two pieces of evidence in sequence, each followed by its own Explanation, before writing the Link. This is sometimes called PEEEL.
2. Counter-PEEL After your main PEEL paragraph on one side of an argument, write a PEEL paragraph that presents a counter-argument—then a third that weighs both. This structure is essential for "to what extent" and "evaluate" questions in History, Economics, and TOK.
3. Thesis-level Links The Link step should not just connect to the next paragraph—it should keep building your overall thesis. Weak Links say "another factor is…"; strong Links say "this evidence qualifies the extent to which X can explain Y, suggesting that…"
Does PEEL Apply to Internal Assessments and Non-Essay Tasks?
Yes, with adaptation. The PEEL logic—claim, support, analysis, connection—applies anywhere you are making an argument in prose.
- Internal Assessment (IA): Whether you are writing an analysis section in a Science IA or an analytical commentary in a Language IA, the same discipline applies: each analytical paragraph should open with a claim, not a description. See the IB IA guide for more on how assessment criteria translate to paragraph expectations.
- TOK Essay: Every paragraph should open with a knowledge claim (the Point), supported by a knowledge example (Evidence), and analyzed through a TOK lens (Explanation). The Link should tie back to the central question.
- Economics Commentary: Paragraphs should drive toward evaluation. A common weakness is stringing together definitions and diagrams without connecting back to a central argument.
A Note on Assessment Criteria and Syllabus Changes
Paragraph frameworks like PEEL and TEEL are tools, not rules. Assessment criteria—what assessors are actually rewarding—vary by subject, task type, and syllabus version. These criteria are updated periodically, and the specific weighting of skills like "analysis," "evaluation," and "application" can shift between assessment cycles.
Before relying on any framework, cross-check your approach with:
- The latest official subject guide for your specific course
- Your supervising teacher or IA supervisor, who knows what the current markscheme rewards
- Past markschemes (where available through your school) to see how top-band responses are described
The structure of a well-reasoned paragraph tends to be stable; the specific language assessors use to describe excellence does change.
Paragraph writing is one of those skills that looks simple but has a high ceiling—students who genuinely internalize the why behind each step of PEEL, rather than mechanically filling in boxes, consistently produce more persuasive, higher-scoring responses. If you want feedback on whether your paragraphs are actually doing what they should in a specific IB subject, working with someone who has written those same assessments themselves tends to shorten the learning curve significantly—which is exactly what the tutors at Quick IB are here for.
