Many IELTS Reading candidates attempt to read every word of every passage — a strategy that inevitably leads to time pressure and poor performance. Effective IELTS readers use two selective reading techniques: skimming (reading for general meaning) and scanning (searching for specific information). Knowing when to use each technique and how to execute both efficiently is one of the highest-value reading skills you can develop.
1Skimming: Reading for the Main Idea
Skimming means reading quickly to understand the overall structure and main ideas of a passage without processing every detail. How to skim: read the title and all subheadings (1–2 seconds each), read the first sentence of every paragraph (where topic sentences are typically located in academic texts), and read the first and last sentences of the introduction and conclusion. This takes approximately 60–90 seconds for a 900-word passage. Use skimming at the start of each passage to build a 'mental map' of where different types of information are located. This makes subsequent scanning dramatically faster.
2Scanning: Locating Specific Information
Scanning means moving your eyes quickly over the text looking for a specific word, phrase, number, or concept — without reading anything else. When to scan: for question types that require specific facts (sentence completion, note completion, short answer questions, T/F/NG). How to scan effectively: identify the keyword from the question (usually a noun, name, or number), move your eyes rapidly down the text looking only for that specific item, and stop only when you see it. Scanning speed improves with practice — beginners scan at about 300 words per minute, experienced scanners at 600–800 words per minute.
3When to Use Skimming vs Scanning
Use skimming: at the beginning of each passage (before answering any questions), when answering matching headings (you need the main idea of each paragraph), when answering global questions about the purpose or organisation of the text. Use scanning: for sentence and note completion (looking for a specific fact), for T/F/NG (locating the relevant passage section), for short answer questions (finding a specific name, date, or definition). For MCQ and matching information, use a combination: scan to locate the relevant section, then read carefully to identify the precise answer. Neither technique is sufficient alone — fluent reading in IELTS combines both.
4Developing Speed: Practical Drills
Drill 1 — Paragraph summary sprint: Read a paragraph and write a 5-word summary in 60 seconds. This builds the main-idea extraction speed that skimming requires. Drill 2 — Keyword scan: Give yourself a word and scan a 500-word text for it as fast as possible. Use a timer. Target: under 15 seconds. Drill 3 — First-sentence skimming: Skim a news article reading only first sentences, then summarise the article. Check your accuracy. Drill 4 — Timed practice passages: Complete a full IELTS reading passage in 17 minutes (under the 20-minute target for a real section). Gradually reduce to 15 minutes. The discomfort of working below your comfortable pace is the training.
🎯 Key Takeaway
Skimming and scanning are learnable skills that develop with deliberate practice. Most candidates improve measurably within two weeks of daily drills. The goal is not to skip information — it is to access information in the right order at the right speed for each question type.
