Skimming and scanning are two essential reading skills for the IELTS Reading test. They allow you to find information quickly without reading every word. Many candidates lose valuable time because they read the passage word for word — a habit that is difficult to break but essential to overcome.
In this guide, I will explain the difference between skimming and scanning and show you how to develop both skills.
What Is Skimming?
Skimming means reading quickly to get the general idea of a text. When you skim, you are not looking for specific details — you are trying to understand what the text is about, how it is organised, and what the main points are.
In the IELTS Reading test, you should skim each passage before you start answering questions. This takes about 2-3 minutes and gives you a mental map of the text. When you later need to find specific information, you will know roughly where to look.
How to Skim Effectively
Read the title and any subtitles. These tell you what the passage is about and how it is organised.
Read the first sentence of each paragraph. The first sentence usually contains the main idea of the paragraph. By reading just the first sentence of each paragraph, you can get a good overview of the entire passage.
Look at any diagrams, charts, or images. These often summarise the main points of the text.
Do not stop at words you do not know. When skimming, you are not trying to understand every word. If you encounter an unfamiliar word, keep going. You can come back to it later if necessary.
What Is Scanning?
Scanning means looking for specific information in a text. When you scan, you are not reading — you are searching for a particular word, name, date, or number. Your eyes move quickly over the text until you find what you are looking for.
In the IELTS Reading test, you scan when you need to find the answer to a specific question. For example, if the question asks “According to the passage, what percentage of the population lives in urban areas?”, you would scan the passage for the word “percentage” or “urban” and then read the surrounding sentences carefully.
How to Scan Effectively
Identify keywords in the question. Before you scan, decide what you are looking for. Underline the keywords in the question and think about synonyms or related words that might appear in the passage.
Move your eyes quickly over the text. Do not read word by word. Instead, let your eyes move rapidly over the text, looking for your keywords. When you find a potential match, stop and read the surrounding sentences carefully.
Look for distinctive features. Names, dates, numbers, and capitalised words are easy to spot when scanning. If the question mentions a specific name or date, look for that first.
Skimming and Scanning in the IELTS Reading Test
Here is how to use skimming and scanning together in the Reading test:
Step 1: Read the questions first. Before you read the passage, read all the questions for that passage. Underline the keywords in each question.
Step 2: Skim the passage. Read the title, the first sentence of each paragraph, and any diagrams or charts. This takes 2-3 minutes and gives you a general understanding of the text.
Step 3: Scan for answers. For each question, scan the passage for the keywords or their synonyms. When you find a potential answer, read the surrounding sentences carefully to confirm.
Step 4: Read carefully. Once you have located the relevant section, read it carefully. The answer is usually in one or two sentences. Do not read the entire passage again — just the section you need.
Common Mistakes
Reading the passage before the questions. This wastes time. Always read the questions first so you know what to look for.
Reading every word. You do not have time to read every word. Use skimming and scanning to find the information you need.
Not using keywords. Always identify the keywords in the question before you scan. Without keywords, you are just reading randomly.
Panicking when you do not know a word. You will encounter unfamiliar words in the Reading test. Do not let them stop you. Use the context to guess the meaning, or simply skip the word and keep going.
Practice Tips
Practise with newspaper articles. Newspaper articles are perfect for practising skimming and scanning. Read the headline and the first sentence of each article to get the main idea. Then scan for specific information — names, dates, numbers.
Time yourself. Give yourself 2-3 minutes to skim a passage and answer general questions about it. Then give yourself 15 minutes to answer detailed questions using scanning.
Read widely. The more you read in English, the better your skimming and scanning skills will become. Read newspapers, magazines, and online articles regularly.
Skimming and scanning are skills that improve with practice. The more you use them, the more natural they will feel. With these techniques, you can save valuable time in the IELTS Reading test and focus your energy on finding the right answers. Good luck!
