TOEFL Build a Sentence: the complete guide (2026 format)

Ten of the twelve items in the current Writing section are Build a Sentence items. This guide explains what one item asks, what the published point allocation is, the patterns that decide most arrangements, and a method that fits the six minutes.

What the task asks you to do

Build a Sentence is the first task in the TOEFL Writing section as it has run since January 21, 2026. Each item gives you a short context — usually one completed sentence — followed by a question, and then a set of scrambled tiles: single words and short phrases, typically six to twelve of them. You arrange every tile into one sentence that is grammatically correct and that answers the question you were given.

Both halves of that sentence matter, and the second one is where prepared candidates lose points. A perfectly grammatical arrangement that answers a different question is still wrong. The task is not a word-order puzzle with one mechanical solution; it is a short comprehension test wearing a grammar costume.

What ETS states

  • The current Writing section lists 12 items: 10 Build a Sentence items, one Write an Email task, and one Academic Discussion task.

  • The 2026 specification lists the Writing section at 12 items and 20 maximum raw points.

  • Per the 2026 specification, the maximum points per Build a Sentence item is 1.

  • Build a Sentence represents 10 of the 20 listed maximum raw points in the Writing specification.

    That is half of the listed raw points, not a claim that it determines half of the final band score; ETS does not publish a simple raw-to-band conversion here.

Sourced from the ETS 2026 test specifications, read 2026-07-27. Everything outside this box is Reach120’s own reading of it.

The six minutes, and what they are actually for

The Build a Sentence set runs about six minutes. Spread across ten items that is roughly thirty-five seconds each, which sounds punishing until you notice how the time actually distributes: most items resolve in fifteen seconds and two or three eat a minute apiece. The pacing skill is not speed. It is knowing, inside ten seconds, which kind of item you are looking at.

PhaseRoughlyWhat you are doing
Read5 secondsRead the context and the question. The question tells you what the sentence has to be about.
Scan the tiles5 secondsFind the subject, the main verb, and any multi-word block that must stay whole.
Build15 secondsPlace the subject and verb, attach the blocks around them, then slot the loose words.
Check5-10 secondsEvery tile used exactly once? Does it answer the question? Read it once in your head.

If an item is still unresolved after about forty-five seconds, place your best arrangement and move on. The published allocation is one point maximum per item, so a minute spent rescuing one arrangement is a minute taken from two you would have got right.

The six patterns that decide most items

These are the six structures the Reach120 Build a Sentence bank is built to exercise, and they are what our worked items are organised around. Learn to recognise them by shape and most items stop being puzzles.

  1. 1Connector attachment. When a tile set contains because, although, while, so or since, the first decision is which clause the connector governs. Get that wrong and the sentence answers a different question — the single most expensive error in the task.
  2. 2Frequency and degree adverbs. Usually, rarely, often and always sit between the subject and the main verb, but after be. Degree words like far, much and slightly bolt directly onto the comparative they modify and never separate from it.
  3. 3Passive kits. A be-form plus a past participle plus a stray by is a passive waiting to be assembled. Build be + participle first, attach the by-phrase, and only then find the slot for the adverb.
  4. 4Noun phrases and articles. An article tile is never free-floating: it belongs to exactly one noun. Assemble the noun chunks before you place anything, and the sentence gets much shorter.
  5. 5Embedded questions. After asked, wondered or know, a question clause returns to subject-then-verb order. "They asked where the hall was", never "where was the hall". This one survives in speech, which is exactly why it is worth drilling.
  6. 6Place before time. When both appear, English defaults to place, then time — and the time phrase keeps its own internal order, day before clock time.

Connector attachment, the expensive one

Weaker

Because they rescheduled, the lab was unavailable on Thursdays.

Stronger

They rescheduled because the lab was unavailable on Thursdays.

Both use every tile and both are grammatical English. Only the second one answers "why was the seminar moved?" — the first reverses cause and effect. Decide what the question wants before you decide where the connector goes.

Five more worked items, each with the wrong arrangement beside the right one, sit on the practice page linked at the end of this guide. They are worth reading before you attempt a timed set, because recognising a trap you have already seen takes a fraction of the time of solving it fresh.

A method that survives the clock

  1. 1Read the question first, then the context. The question is the constraint; the context only supplies the situation.
  2. 2Find the main verb tile. Everything else in the sentence is positioned relative to it, so locating it first collapses most of the search space.
  3. 3Assemble the blocks. Multi-word tiles, noun phrases and comparatives move as units. Treat them as single pieces and a twelve-tile item becomes a five-piece one.
  4. 4Place the connector last, and place it deliberately. Ask which half of the sentence is the reason and which is the result before you commit.
  5. 5Read the finished sentence against the question, not against your ear. "Does this sound right" is a weaker test than "does this answer what was asked".

Five mistakes worth training out

  • Answering the context instead of the question. The context is scene-setting. Only the question defines a correct answer.
  • Splitting a unit to make an adverb fit. If the only way to place a word is to break a prepositional or comparative phrase, the word belongs somewhere else.
  • Carrying question inversion into a reported clause. "She asked when does the bus leave" feels natural and is wrong.
  • Leaving a tile unused because the sentence already reads well. A well-formed sentence that drops a tile scores nothing.
  • Rescuing one hard item at the cost of two easy ones. Each item carries the same published maximum. Budget accordingly.

How to practise this task without wasting sessions

Untimed accuracy first, then timed accuracy — in that order, and not the other way round. Drilling under time before the patterns are automatic trains you to make your habitual error faster.

  1. 1Week one: untimed sets, and after every miss write down which of the six patterns caused it. The list of patterns you personally miss is usually two items long, not six.
  2. 2Week two: timed sets at forty-five seconds per item, checking only for those two patterns.
  3. 3Week three: full six-minute sets, then one review pass where you rebuild every missed item from scratch rather than reading the answer.

A raw item count is evidence about grammar control, not a predicted official score. Official score reports for tests taken on or after January 21, 2026 use 1-6 bands in half-band increments, and no simple conversion from raw items to bands is published — so treat "eight of ten" as a diagnostic, which is exactly what makes it useful week to week.

Build a Sentence: common questions

How many Build a Sentence items are on the test?
The 2026 specification lists 12 Writing items in total: 10 Build a Sentence items, one Write an Email task and one Academic Discussion task. The specification was read on 2026-07-27 and states that blueprint values are subject to minor revision.
How many words do you get in a Build a Sentence item?
Typically six to twelve tiles, and a tile can be a single word or a short phrase. You must use all of them exactly once in one sentence.
Is Build a Sentence multiple choice?
No. You are not choosing between written options; you arrange the tiles yourself. The specification publishes a maximum of 1 point per Build a Sentence item and describes the task type as machine-scored. Reading that as a correct-or-incorrect judgement rather than a rubric score is our interpretation, not an ETS statement.
How much of the Writing score does Build a Sentence carry?
It represents 10 of the 20 listed maximum raw points in the Writing specification. That is half of the listed raw points, not a claim that it determines half of the final band score; ETS does not publish a simple raw-to-band conversion here.
What grammar should I review for this task?
Connector attachment, adverb placement, passive constructions, article and noun-phrase assembly, embedded question order, and place-before-time ordering. Those six are the structures the Reach120 Build a Sentence bank is built to exercise, and the guide works through each one.
Can I practise Build a Sentence for free?
Yes. The worked examples on the practice page, the topic browser and the printable task pack are all free and need no account. AI-scored Writing practice needs a paid plan, which carries a monthly fair-use allowance; the scoring on this task type is rule-based rather than AI-scored.
