IELTS Reading Completion and Short-Answer Questions

By Muntasir Jul 29, 2026 7 min read

TL;DR

IELTS Reading completion and short-answer questions share one rule: your answer must use exact words from the passage, inside the stated word limit. A typical instruction reads NO MORE THAN TWO WORDS AND/OR A NUMBER. These are three of the eleven official Academic Reading question types, and they take four shapes on the page. Sentence Completion fills a gap in one sentence. Summary and Note Completion fills gaps in a summary or notes. Table and Flow-chart Completion fills gaps in a table or a flow-chart. Short-answer Questions answer a direct factual question, in passage order. Go over the word limit and you lose the mark, even when the extra word is correct. Spelling and grammar mistakes cost the mark too.

Three of the eleven official IELTS Academic Reading question types ask you to produce a word from the passage instead of picking an answer from a list, according to IELTS: Sentence Completion, Summary/Note/Table/Flow-chart Completion, and Short-answer Questions. Those three split into four task shapes on the page: Sentence Completion, Summary & Note Completion, Table & Flow-chart Completion, and Short-answer Questions. Each shape carries a strict word limit, and going over it costs you the mark even when the wording is right. Diagram label completion, a separate official question type, follows the same word-limit rule, so read the four shapes below as one grouping and not as the full list of word-limited tasks.

This guide covers the skill shared across all four subtypes, how each one differs from the others, and the exact penalties which cost you marks. Unlike Multiple Choice questions, where you pick from options printed on the page, these four subtypes ask you to write the word yourself, straight from the passage. For the full Reading section format, including timing and passage types, see our IELTS Reading section guide. This article closes with practice for every subtype below.

The Shared Skill: One Exact Word, Under a Limit

All four subtypes need one skill: finding the exact word or words in the passage which fill the gap or answer the question, then copying them without changing the spelling. Answers must be taken from words in the text, according to IELTS. You are not summarizing the passage in your own words here. You are locating the word the passage already uses and placing it in the right spot.

Reading the Word-Limit Instruction

Read the instruction line above the questions before you answer a single one. Word limits vary by task, and a typical instruction reads NO MORE THAN TWO WORDS AND/OR A NUMBER, according to IELTS. Miss this line and you risk writing a two-word answer under a one-word limit, or adding an extra word past the stated cap, both of which lose you the mark.

The Four Subtypes Compared

The table below lines up what each subtype asks you to produce and how the task looks on the page.

Subtype	What You Produce
Sentence Completion	A missing word in a single given sentence
Summary & Note Completion	Missing words in a summary paragraph or a list of notes
Table & Flow-chart Completion	Missing words in a table or a flow-chart diagram
Short-answer Questions	A short factual answer, in word or number form, to a direct question

Sentence Completion

Sentence Completion gives you one sentence with a gap in it, and you fill the gap using words taken directly from the passage, according to IELTS. This subtype tests your ability to locate one specific detail, rather than your grasp of the whole passage. The grammar around the gap narrows the search before you start scanning: an article in front of the gap points to a noun, and a plural verb after it points to a plural subject. Read the full sentence first, decide what kind of word fits, then hunt the passage for the detail behind it.

Summary & Note Completion

Summary & Note Completion completes a summary paragraph or a set of notes using words from the passage, according to IELTS. Matching information does not have to follow the same order as the passage, according to the same source, so the detail you need is not guaranteed to sit near the earlier gaps. This subtype checks both a specific detail and your overall grasp of the passage.

Table & Flow-chart Completion

Table & Flow-chart Completion follows the same underlying rule as Summary & Note Completion, filling gaps with words taken from the passage, according to IELTS. The missing words sit inside a table with rows and columns, or inside a flow-chart showing a sequence of steps, instead of inside prose. IELTS counts summary, note, table and flow-chart completion as a single official question type, and this guide splits it in two because the two layouts reward different scanning habits. As with summary completion, the order of the gaps does not need to match the order of the details in the passage.

Short-answer Questions

Short-answer Questions ask a factual question about the passage, and you answer in word or number form using words taken from the passage, according to IELTS. Unlike the three completion subtypes above, short-answer questions follow the same order as the passage, according to the same source: the answer to question one sits before the answer to question two, and so on. This order makes short-answer questions the most predictable of the four for pacing.

Penalties: What Costs You the Mark

These four subtypes share one set of marking rules, and breaking any one of them costs you the mark. None of the mistakes below has anything to do with understanding the passage, since each one turns a correct idea into a lost mark on the answer sheet. The table lists each mistake and why it costs you.

Mistake	Why It Costs You
Writing more words than the limit allows	You lose the mark for writing more than the word limit, according to IELTS
Using a word not found anywhere in the passage	The answer does not count, since answers must be taken from words in the text
Misspelling a word copied from the passage	You lose marks for incorrect spelling, according to IELTS
Wrong grammar when you copy the answer onto the sheet	You lose marks for incorrect grammar too, under the same rule

IELTS does not name wrong word form, using a noun where the sentence needs a verb, for example, as its own separate penalty. The official format page names incorrect spelling and grammar as the marks you lose when transferring answers, so a wrong word form sits under the grammar half of the same rule, according to IELTS. The practical effect is identical either way, because the answer sheet is marked on the words you wrote and nothing else. Read the finished sentence back once before you move to the next question.

Practice by Subtype

Each subtype below has its own drill group in our IELTS practice, with 10 sets per level and 10 questions per set, so you build the skill in stages before facing it inside a full timed passage. Every set pairs one passage with 10 typed answers, and the easy, medium and hard levels run the same task on longer and longer texts.

Sentence Completion drills: each set gives you 10 gapped sentences against one passage, answered by typing the exact passage words. Easy sets use the shortest passages, and medium and hard sets stretch the same 10 gaps over longer texts, so locating each detail takes a wider scan.
Short-Answer Questions drills: each set asks 10 direct factual questions on one passage, answered in word or number form, with answers appearing in passage order. Easy sets keep the passage compact, and hard sets lengthen it, so the passage-order rule saves more time as the text grows.
Summary & Note Completion drills: each set pairs one passage with a gapped summary or set of notes holding 10 blanks to fill. Easy sets place every detail inside a short text, and hard sets spread the same 10 details across far more prose, so the gaps stop lining up with nearby sentences.
Table & Flow-chart Completion drills: each set turns one passage into a table or flow-chart with 10 blanks, so you practice moving details from prose into a structure. These sets use the longest passages of the four groups at every level, and the hard sets run the longest of all, which rewards scanning for rows and steps instead of re-reading in full.

Our free IELTS Reading practice on the IELTS exam page runs all four drill groups above, plus full-length Reading sections under the real section timer. Every set is free, with no signup required, and every answer comes with an explanation. Start with the subtype which felt hardest above, then add a second subtype once you clear the first without missing more than one or two.
