IELTS Reading Summary Completion: Strategies & Practice Tips

Summary completion questions test your ability to understand the main points of a passage and find specific information to fill gaps in a condensed version of the text. They come in two variations: with and without a word list. Both require careful reading and precise answers, but they demand slightly different strategies.

This guide covers both variations and gives you the techniques needed to maximise your score on this question type.

Two Types of Summary Completion

Type 1: Without a Word List

You must find words directly from the passage to complete the summary. The instructions will specify a word limit, such as "NO MORE THAN TWO WORDS" or "NO MORE THAN THREE WORDS AND/OR A NUMBER."

Type 2: With a Word List

You are given a box of possible answers (often 8-12 options) and must choose the correct word to fill each gap. The words may not appear in the passage — they may be synonyms or paraphrases.

Strategy for Type 1: Words From the Passage

Step 1: Read the Summary First

Read the entire summary before looking at the passage. This gives you:

• An overview of what section of the passage is being tested
• Context for each gap (what type of information is missing)
• Keywords to scan for in the passage

Step 2: Identify What Each Gap Needs

For each gap, determine:

• What type of word is needed? (noun, verb, adjective, number)
• What is the topic of the sentence?
• What grammatical form fits? (singular/plural, past/present)

Example: "The experiment involved measuring the _______ of participants before and after the treatment."

Grammar tells you this needs a noun (after "the"). The context tells you it is something measurable about people. Possible answers might be "blood pressure," "heart rate," or "weight."

Step 3: Locate the Relevant Section

The summary usually covers a specific part of the passage, not the entire text. Use keywords from the summary to locate the relevant paragraphs.

Important: The gaps in the summary follow the same order as the information in the passage. So if gap 1 is in paragraph 3, gap 2 will be in paragraph 3 or later — never earlier.

Step 4: Find the Exact Words

Once you locate the relevant sentence, find words that:

• Fit the grammar of the gap
• Match the meaning required by the summary context
• Stay within the word limit

Step 5: Check the Word Count

Count your words carefully:

• Hyphenated words (like "well-known") count as one word
• Numbers written as figures (like "35") count as one word
• "A" and "the" count as words

Strategy for Type 2: With a Word List

Step 1: Read All Options

Before reading the summary, scan the word list and note:

• The types of words (nouns, verbs, adjectives)
• Any obvious pairs or groups (synonyms, antonyms)
• Words you recognise from the passage

Step 2: Read the Summary and Predict

Read each gap in context and predict what type of word fits:

• Does the gap need a noun, adjective, or verb?
• What meaning would make the sentence logical?

Step 3: Use Grammar to Eliminate Options

Even before checking the passage, you can eliminate options that do not fit grammatically:

• If the gap follows "a," the word must be a singular noun or adjective
• If the gap follows "are," a plural noun or adjective is needed
• If the gap is after "to," a base form verb is likely

Step 4: Match Meaning Using the Passage

For the remaining options, check the passage to confirm which word accurately reflects the information presented. The summary will paraphrase the passage, so look for synonyms and reworded ideas.

Grammar Clues for Filling Gaps

Your grammar knowledge is a powerful tool for summary completion:

Articles and Determiners

• "the _______" → noun expected
• "a _______" → singular countable noun expected
• "many _______" → plural countable noun expected
• "much _______" → uncountable noun expected

Prepositions

• "in the _______ of" → noun expected
• "by _______ the" → verb in -ing form expected
• "for _______ reasons" → adjective expected

Verb Patterns

• "they _______ the" → verb expected
• "was _______ by" → past participle expected (passive voice)
• "to _______ the problem" → base form verb expected

Conjunctions and Parallel Structure

• "_______ and efficient" → adjective expected (parallel with "efficient")
• "the cost and _______" → noun expected (parallel with "cost")

Worked Example

Passage excerpt: "The researchers divided 200 participants into two groups. The first group was given a daily dose of the herbal supplement, while the second group received a placebo. Over a twelve-week period, those taking the supplement reported a 40% reduction in symptoms of anxiety, compared to only a 12% reduction in the placebo group. However, the researchers noted that participants who also exercised regularly showed the most significant improvements, regardless of which group they were in."

Summary (Type 1 — NO MORE THAN TWO WORDS AND/OR A NUMBER): "In the study, _______ (1) participants were split into two groups. The supplement group experienced a _______ (2) decrease in anxiety symptoms over _______ (3) weeks. The researchers observed that _______ (4) was the factor most strongly associated with improvement in both groups."

Answers:

1. 200 — directly from "200 participants"
2. 40% — from "40% reduction in symptoms of anxiety"
3. twelve / 12 — from "twelve-week period" (either form acceptable)
4. regular exercise — from "participants who also exercised regularly showed the most significant improvements"

Note how answer 4 requires you to paraphrase slightly — the passage says "exercised regularly" but the summary gap needs a noun phrase. "Regular exercise" captures the meaning within the word limit.

Common Mistakes

1. Exceeding the Word Limit

The word limit is absolute. "The local hospital" is three words. If the limit is two words, you must write "local hospital" (dropping "the") or find a shorter answer.

2. Changing Word Forms

When pulling words from the passage, do not modify them unless the summary's grammar requires it. If the passage says "significant" and your gap needs an adverb, the answer might be nearby — look for "significantly" in the passage itself rather than changing the form.

3. Copying Too Much Context

Only write the words that fill the gap, not the surrounding words from the passage.

4. Ignoring Grammar Clues

If your answer does not make the sentence grammatically correct, it is wrong. Read the completed sentence back to yourself and check that it sounds natural.

5. Looking in the Wrong Section

Remember that the summary typically covers a specific section of the passage, and gaps follow passage order. If you are searching the entire passage for each answer, you are wasting time.

Practice Plan

Summary completion rewards candidates who can skim effectively and pay attention to grammatical detail. Here is how to build these skills:

1. Practice grammar identification — Read sentences with blanks and predict the word type needed before looking for the answer
2. Build scanning speed — Time yourself finding specific information in passages
3. Check word counts — After every practice answer, count your words immediately
4. Use CambPrep's reading practice — Reading exercises include summary completion questions with instant feedback on your answers
5. Review your errors — Track whether your mistakes are due to wrong location, wrong word form, or exceeding the word limit

Frequently Asked Questions

What happens if I write more words than the limit allows?

Your answer will be marked wrong, even if the content is correct. The word limit is strictly enforced. Always count your words before writing your final answer.

Should I write the answer in uppercase or lowercase?

Either is fine. Capitalisation does not affect scoring in IELTS Reading. However, proper nouns should be capitalised as they appear in the passage.

Can the answer span across two sentences in the passage?

Typically, no. The answer for each gap usually comes from a single sentence in the passage. If you find yourself combining words from two different sentences, reconsider your answer.

How do I handle the summary if it covers a different order from the passage?

While gaps generally follow passage order, the summary might reorganise information slightly. If you cannot find an answer where you expect it, look in the surrounding paragraphs. The information is usually nearby.
