The TOEFL Academic Discussion: How to Write a Post That Actually Scores
You have about 10 minutes and one screen. Here is the exact structure that earns full marks — and the one mistake that quietly costs students a whole band.
WritingIn the Academic Discussion task, a professor asks a question and two classmates have already replied. Your job is to add your own contribution. It looks casual. It is not. There is a precise formula the graders reward, and most students miss at least one part of it.
Five things every high-scoring post contains
Miss any one of these and you cap your own score, no matter how good your English is.
State your position immediately
The grader wants to know where you stand before they read anything else.
Give two reasons, not one
A single reason, however good, makes your post feel under-developed. Use simple ordering words so the grader can see both clearly.
Use: First of all… / Secondly… / Furthermore… / Finally…
Structure beats vocabulary. A post organised with First of all… Secondly… In conclusion… reads as academic even when the words are simple.
Make one thing concrete
General claims are forgettable. One specific detail makes your whole post more convincing.
The mistake that costs a whole band
This is the big one. You must engage with a classmate by name — and you must represent their argument accurately.
We regularly see posts where a student writes “I agree with Alvin” when Alvin actually argued the opposite of what the student is saying. That single error makes the whole response look as though it was not read properly, and it undercuts your own position.
Before you write their name, re-read their post. Ask one question: is this person on my side or not? Then choose your phrase — “I agree with Kelly that…” or “Unlike Adam, I believe…”
Watch these recurring grammar slips
- Countable nouns: companies need fewer workers, not less workers.
- Subject-verb agreement: field trips improve interest, not field trips improves.
- Articles: it is a good idea, not it is good idea.
- Word forms: advanced skills, not advance things.
- Connectors: use In conclusion, not At last.
A model skeleton you can reuse
- Position: In my opinion, [your side].
- Reason 1: First of all, [reason], because [explanation].
- Example: For example, [something concrete].
- Reason 2: Secondly, [reason].
- Classmate: I agree with [Name] that… or Unlike [Name], I believe…
- Close: In conclusion, [restate your position].
Six sentences. A clear side, two reasons, one concrete example, one classmate named accurately, and a proper ending. That is a full-mark post.
