An applicant scores 7.0 overall on IELTS, half a band above the university's requirement, yet receives only a conditional offer. The programme requires at least 6.5 in each skill, and her Writing score is 6.0. She now has five weeks before the offer deadline to resit, and every test date in her city is fully booked.
Language tests are the most measurable part of an application, and also the part many people plan last. This guide helps you choose the right test, read requirements accurately and practise where it counts.
Reading the requirement: the overall score is only half of it
A programme's language requirement usually has three layers:
- A minimum overall score.
- Minimum scores for each skill: listening, speaking, reading, writing. Many social science and law programmes set a higher bar for writing.
- A list of accepted tests, with rules about format: test centre, computer-delivered or at home.
One detail often missed: the requirement for your visa may differ from the university's. In some countries the test used for immigration purposes must be a specific approved version. Read both pages before you book.
Comparing the common tests
| Test | Format | Strengths | Watch out for |
|---|---|---|---|
| IELTS Academic | Paper or computer; face-to-face speaking | Very widely accepted, especially in the UK, Australia and Canada | Writing criteria are clear but the score is slow to move |
| TOEFL iBT | Fully computer-based | Common in the US and across North America | Format and scoring have changed recently; read the latest guidance |
| PTE Academic | Computer-based, automated scoring | Fast results; accepted by many Australian and UK universities | Integrated tasks mix skills; practise with the interface |
| Duolingo English Test | At home, adaptive | Flexible scheduling, short duration | Not accepted everywhere; rarely valid for visas |
| Cambridge C1 Advanced / C2 Proficiency | Paper or computer | The certificate itself does not expire | Many universities still only accept recent results |
Universities commonly treat scores as valid for about two years from the test date, though each sets its own rule. Test too early and your certificate may expire before you enrol.
Choosing a test: four questions
- Do all the universities on your list accept it? Pick the test that covers the most of them.
- Is it valid for the visa you will need?
- Do you prefer paper or screen? Slow typists often struggle with computer-based writing.
- Do you speak better to a person or to a microphone? IELTS speaking is with an examiner; TOEFL and PTE are recorded.
Schedule backwards from your deadline
A safe rule: have a qualifying score at least two months before your earliest application deadline. To get there:
- Sit your first attempt four to five months before the deadline, leaving room for one resit.
- Check how long results take and how they reach universities; some are sent electronically, others need an institution code.
- Book early in peak season; in large cities, autumn test dates fill up quickly.
Some testing systems let you resit a single skill. If yours does, confirm that your target universities accept that kind of result before relying on it.
Train your weakest skill
A common mistake is to practise all four skills equally when only one is below the threshold. Take a full mock test under real conditions, identify the lowest skill, and give it about 60 per cent of your remaining time.
Writing
This is where many test takers lose the most marks. Learn the published marking criteria and assess yourself against each one: task response, coherence, vocabulary and grammar. Write one timed essay a day, and have someone experienced mark at least one a week. Writing a lot without feedback mostly rehearses your existing errors.
Speaking
Record your answers, play them back and transcribe them. On paper you will see abandoned sentences, repeated words and long pauses. Practise on familiar academic topics, such as your subject or a project, where your vocabulary is richest.
Listening and reading
These improve fastest with systematic practice and error analysis. Was a mistake caused by unknown vocabulary, a paraphrase trap, or running out of time? Log the type of error, not just the number of wrong answers.
Try this: an eight-week plan for a skill half a band short
| Week | Main task |
|---|---|
| 1 | Full mock test; read the marking criteria; list your three most frequent errors |
| 2–3 | Target each error separately with a short daily exercise |
| 4 | Mock test on the weak skill; get it marked and compare with week 1 |
| 5–6 | Timed practice under real conditions; one task a week to maintain the other skills |
| 7 | Second full mock test |
| 8 | Ease off, review criteria, and rest before test day |
When you may not need a test at all
Some universities waive the requirement if you completed a full degree taught in English, or come from a majority English-speaking country. Whether an English-taught programme in a non-English-speaking country qualifies varies widely; some universities ask for a medium-of-instruction letter from your previous institution. Ask the admissions office directly before assuming you are exempt.
A task for this week: open the language requirement pages of your three top-choice universities, copy the overall and per-skill minimums into a table, and take the highest of each as your target. Then sit a full mock test to see how far you are from that target in every skill.
Câu hỏi thường gặp
Should I take IELTS or TOEFL to study abroad?
Choose the test that every university on your list accepts and that works for your visa. IELTS is common for the UK, Australia and Canada, TOEFL for the US, but most universities accept both.
How long are IELTS results valid for university applications?
Many universities accept results for about two years from the test date, but the exact rule varies. Check each university's admissions page.
What if my overall score is fine but one section is too low?
If the programme sets per-skill minimums, you will usually not meet the requirement. You may receive a conditional offer and need to resit or complete a pre-sessional English course.
Is the Duolingo English Test accepted by universities?
Some universities accept it, particularly in the US, but not all, and it is rarely valid for student visas. Check the accepted tests list for every institution you apply to.
How early should I take an English test before applying?
Aim for a first attempt four to five months before your deadline, so you have a qualifying score at least two months ahead and time for a resit if needed.
