IELTS Reading Summary Completion: How to Beat the Word Limit

Summary completion is the question type where I see the most avoidable lost marks in IELTS Reading. The idea is simple: a short summary of part of the passage has gaps, and you fill each gap with words from the text. The trouble is that you can understand the passage perfectly and still lose the mark on a technicality. This post is about those technicalities, so that IELTS Reading summary completion stops costing you points you already earned.

The word limit is a rule, not a hint

Above the summary you will see an instruction such as "Write NO MORE THAN TWO WORDS from the passage for each answer" or "Write ONE WORD ONLY". Some versions add "AND/OR A NUMBER".

Treat that line as part of the question. If the limit is two words and you write three, the answer is marked wrong even when it is exactly the right idea. The limit is a maximum, so one word is allowed when two are permitted, but you can never go over.

The limit can change from one task to the next within the same test. I have seen one summary allow one word and the next allow two. Check it every single time, before you read the summary.

Read the summary first, then the passage

Skim the whole summary before you go to the passage. It is a compressed version of one section of the text, so it tells you the topic and the order of ideas. Underline the words around each gap, because those are your search keys.

For example, take this summary sentence:

Early settlers relied on the river mainly for ______ and for moving goods inland.

Your search keys are "settlers", "river" and "moving goods". You scan the passage for those ideas, not for the missing word itself, because you do not know it yet.

Find the paragraph, then the gap

In most summary tasks the gaps follow the order of the passage. Once you find where gap 1 is answered, gap 2 is almost always further down, never above it. This saves a great deal of time under a 60-minute limit for 40 questions.

Locate the right paragraph using the keywords, then read that paragraph slowly. The passage will usually paraphrase the summary rather than repeat it:

Early settlers depended on the river chiefly for fishing, and it also served as the route along which cargo travelled to the interior.

Summary: "for moving goods inland" has become "the route along which cargo travelled to the interior". The answer, "fishing", sits right beside the paraphrase. Learn to hear the paraphrase and the answer appears next to it.

Let grammar tell you what the gap needs

Before you look for the word, decide what kind of word the gap needs. In the example above, "relied on the river mainly for ______ and for moving goods" needs a noun or a gerund, because it follows "for" and is joined by "and" to "moving goods". A verb or an adjective cannot fit.

This does two jobs. It stops you picking a nearby word that has the wrong form, and it helps you choose between two candidates in the same sentence. If the gap needs a plural noun, "settlements" is possible but "settlement" is not.

Copy the word exactly

The answer must come from the passage, in the form it appears there. Do not change "farmers" to "farming" to make the sentence fit. If the summary needs a different form, you have probably found the wrong word, so go back to the passage.

Spelling counts as well. In Reading there is no extra time to copy answers over, so you write each answer directly on the answer sheet while you work, and a misspelt word is marked wrong. Copy the spelling letter by letter from the passage. Check capital letters and plurals too.

Numbers and hyphens

When the instruction says "AND/OR A NUMBER", a figure is a legal answer, and you can write it as digits or as words, whichever the passage uses. Copy the form you see.

Hyphenated words are a common source of doubt. In the answer keys of Cambridge practice tests that I have checked, a hyphenated word such as "long-term" counts as one word. Do not rely on this alone: if a limit of one word is set and your answer is hyphenated, look again at whether a single word fits better.

When there is a box of words

Some summary tasks give you a list of words (A to I, for example) and ask you to choose the letter. These are different. Here you write a letter, not a word, so the word limit and the spelling rules do not apply.

The box usually has more words than gaps, and the extras are chosen to look attractive. The grammar check from above is your best filter: first decide the part of speech of the gap, then cross out every box word of another type. Then match the meaning to the paraphrase in the passage.

A routine for the 60 minutes

This is the order I follow for each summary task:

1. Read the instruction line and note the word limit.
2. Skim the whole summary and underline the words around each gap.
3. Find the passage paragraph that matches the first gap.
4. Decide what part of speech the gap needs, then find the paraphrase and the answer next to it.
5. Copy the answer exactly, count the words, and check the spelling.

Give each summary task a fixed budget. If one gap does not appear after a minute or so, write a guess and move on, because the other gaps in the same task may point you to it.

Practising it

Practise on whole tests under timing, then review each wrong answer and ask which of the five steps you skipped. I am not an IELTS teacher, so I always check the official wording of task instructions on the British Council, IDP and Cambridge sites.

On Toey, Cambridge 14 to 16 Reading and Listening tests are free, and scoring is instant. It is web only for now, with no mobile app yet, and it does not explain a wrong summary answer paragraph by paragraph, so keep your own error log of which step failed.
