16Word: the free English level test — A1 to B2 in about 8 minutes, no account needed

What IELTS measures

IELTS is delivered by the British Council and IDP. It has one part for each skill: reading, listening, writing and speaking. Because all four count, a strong reader with hesitant speech cannot hide the gap. The test types are described one by one on the official site, so check which type your university or authority names before you book.

How the band works

Your result is a band from 0 to 9. There is no general pass mark to aim at: the number that matters is the one written in the requirements of the place you are applying to. Find that number first. It decides how long you need to prepare, and it may differ between a course, a job and a visa.

Write your target band at the top of your study plan, with the name of the institution that asked for it. If the requirement mentions a minimum per skill, write that down too.

Test centre or at home

The official site offers IELTS at a test centre and at home. Before you choose the home option, confirm that the organisation receiving your result accepts it. You can look for a centre on the official test centre page.

How long a result counts

IELTS gives two years as the recommended limit for using a result. If you plan to apply later than that, take the test closer to your application. An institution may also set its own rule, so read its page rather than assuming.

A preparation plan that fits real life

  1. Take a free English level test to see where you stand between A1 and B2.
  2. Decide your target band and read the requirement of the institution that set it.
  3. Build vocabulary every day: 16 words in about five minutes, with spaced repetition so that they stay.
  4. Move from words to whole sentences and dialogues, where grammar and word order show up.
  5. Work through the official sample questions and time yourself.
  6. Book the test only when your timed practice is close to the band you need.

What to practise for each skill

  • Reading: read a little every day and note the words that stop you. Those are your next vocabulary set.
  • Listening: listen to the same short recording twice, the second time checking every word you missed.
  • Writing: write full answers by hand or on screen, whichever you will use on the day.
  • Speaking: say your answers aloud. Being able to recognise a word and being able to produce it are different skills.

Start with your own path

Tell us your goal and your level. 16Word builds a personal plan that points you to words, sentences and dialogues at the right level.

16Word's paths go up to B2, and we do not offer IELTS mock tests. Use the app for vocabulary and active recall, and the official samples for the exam format.

Comparing exams before you commit? Read IELTS, TOEFL, PTE or Cambridge, and check how long language certificates stay valid. If you are preparing to study abroad, see language exams for studying abroad.
