TOEFL Writing Practice: Build a Sentence, Email and Academic Discussion

TOEFL Writing in 2026 is twelve items in about twenty-three minutes. Most preparation material still treats Writing as two long essays, which is now wrong in both structure and emphasis.

Ten of the twelve items are Build a Sentence — a machine-scored grammar task. The other two are short constructed responses. That distribution should shape how you spend practice time.

Build a Sentence — 10 items

The blueprint describes this as reconstructing a range of sentence structures, targeted across A1–C2. It is machine scored, meaning there is a defined correct answer rather than a judgement call.

This is the highest-yield thing to practise in the whole Writing section, and the one candidates most often ignore because it does not feel like "writing".

What it rewards

Knowing how English clauses assemble. Specifically:

• Word order in statements, questions and negatives
• Clause subordination — relative clauses, that-clauses, adverbial clauses
• Verb complementation — which verbs take an infinitive, which take a gerund, which take a that-clause
• Participle and reduced clauses — Having finished the report, she…
• Inversion and fronting at the higher levels — Not until the results arrived did we…

How to practise

The most efficient drill is sentence reconstruction from scrambled parts.

1. Take a sentence from any well-edited source — a textbook, a news article, an academic abstract.
2. Break it into its component chunks and shuffle them.
3. Come back a day later and reassemble it.
4. Check against the original.

Fifteen sentences a day takes about ten minutes and directly targets the largest item block in the section.

When you get one wrong, name the rule you missed. "I put the relative clause after the wrong noun" is a usable correction; "I got it wrong" is not.

Common failure points

Write an Email — 1 item

New in 2026. The blueprint places it in the academic navigational context and describes it as writing appropriate multi-sentence text, targeted at B1–C2.

Academic navigational means the practical business of being a student: writing to a professor about a deadline, to an administrator about enrolment, to a classmate about a group project.

What the email task rewards

Register as much as accuracy. An email to a professor and an email to a classmate are not written the same way, and choosing wrongly is a content error, not just a stylistic one.

A reliable structure:

1. Purpose sentence. Why you are writing, in one line.
2. Context. The relevant background, briefly.
3. The specific request or information. Be concrete.
4. Close. Appropriate to the relationship.

Prompt: You cannot attend Thursday's seminar because of a medical appointment. Write to your professor.

Dear Professor Alvarez,

I am writing to let you know that I will not be able to attend Thursday's seminar, as I have a medical appointment that could not be rescheduled.

I have read the assigned chapters and will complete the response paper by the usual deadline. If the seminar discussion covers material that is not in the readings, I would be grateful if you could point me to the relevant notes, or I can ask a classmate for a summary.

Apologies for the inconvenience.

Best regards, Marta

Note what it does: states the purpose immediately, gives just enough context, proposes a solution rather than only presenting a problem, and closes appropriately. It does not apologise three times or explain the medical appointment in detail.

Register markers worth knowing

Match the register to the recipient the prompt names. Over-formality with a classmate reads as oddly as informality with a professor.

Write for an Academic Discussion — 1 item

This task survived the 2026 update. The blueprint describes it as writing academic paragraph text that presents a clear, well-supported argument using varied grammar and vocabulary, targeted at B1–C2.

You are given a discussion-board scenario: a professor poses a question, two students have responded, and you contribute.

The four-move structure

1. Position. State what you think, plainly, in the first sentence.
2. Reason. Why — the mechanism, not just the assertion.
3. Support. A specific example, consequence or scenario.
4. Engagement. Connect to one of the other students, either extending or qualifying their point.

The fourth move is what distinguishes a discussion response from a mini-essay, and it is the one most often missing.

I would side with Amara on this, though for a slightly different reason. Requiring students to take courses outside their major is worth the timetable cost, mainly because the habit of reading unfamiliar material is itself the transferable skill — not the content of any particular elective. A biology student who has had to argue about historical evidence has practised evaluating claims where the standards of proof are different from their own field, and that is exactly the situation most graduates face at work. Daniel's concern about workload is fair, but it argues for fewer required electives rather than none.

That is about 110 words and does all four moves. See our academic discussion examples guide for more worked responses.

Length

Aim for a developed paragraph of roughly 100–140 words. Beyond that you are usually repeating yourself, and under 80 you have probably not supported the position.

How to split your practice time

Given ten of twelve items are Build a Sentence, a sensible weekly split:

• 50% sentence reconstruction drills
• 25% academic discussion responses, timed
• 25% email tasks across different recipients and registers

That is close to the opposite of how most people prepare, and it matches where the items actually are.

What to stop practising

Integrated Writing. Reading a passage, listening to a lecture that contradicts it, and summarising the relationship is not on the 2026 test. It is still a reasonable exercise for source synthesis, and some platforms keep it available as classic practice, but do not spend TOEFL preparation time on it as though it will appear.
