English proficiency tests are standardized exams that measure how well a person can read, write, listen to, and speak English. Universities, immigration authorities, employers, scholarship boards, and professional licensing bodies use these scores to confirm that a candidate can function in an English-speaking academic, workplace, or civic environment. The most widely recognized options are IELTS, TOEFL iBT, PTE Academic, the Duolingo English Test, Cambridge English Qualifications, TOEIC, EIKEN, CELPIP, and OET — each built for a slightly different purpose, audience, and country. This guide compares them all so you can pick the right one for your goals and prepare with confidence.
What Is an English Proficiency Test?
An English proficiency test is a standardized assessment that measures a non-native (and sometimes native) speaker’s practical command of English across four core skills: reading, writing, listening, and speaking. Scores are reported on a defined scale — bands, points, or grades — and are accepted by institutions as objective, comparable evidence of language ability.
Definition box
An English proficiency test evaluates real-world communication skills rather than grammar knowledge alone. Results are typically valid for one to two years (Cambridge exams are a lifetime-validity exception) and are sent directly to institutions or downloaded as official score reports.
Who accepts these scores?
- Universities and colleges, for admissions and program placement
- Immigration and visa authorities, for permanent residency, work visas, and citizenship
- Employers, particularly in aviation, healthcare, hospitality, and multinational corporations
- Professional licensing boards, such as nursing and medical councils
- Scholarship and exchange programs, which often set a minimum band or score
Scores matter because they replace subjective judgments about fluency with a standardized, internationally recognized benchmark that institutions can compare across thousands of applicants from different countries and educational backgrounds.
Why Are English Proficiency Tests Important?
English proficiency tests exist because institutions need a fair, consistent, and verifiable way to confirm language ability before granting admission, a visa, a license, or a job offer — replacing guesswork with a documented score that can be checked against a stated minimum requirement.
- Study abroad: Nearly all English-medium universities require a proficiency score for non-native applicants before issuing an offer letter.
- Immigration: Countries such as Canada, Australia, the UK, and New Zealand require an approved test (a Secure English Language Test, or SELT, in the UK’s case) for most skilled migration and permanent residency pathways.
- Employment: Multinational employers and specific industries — airlines, hospitals, call centers — often set proficiency thresholds during hiring.
- Professional licensing: Nursing, medical, and other regulated professions frequently require OET or an equivalent score before a license or registration is issued.
- University admissions: Both undergraduate and graduate programs set minimum band or point requirements that vary by faculty and by test.
- Scholarships: Many scholarship boards (Fulbright, Chevening, Erasmus Mundus, and others) require a proficiency score as part of a complete application.
Major English Proficiency Tests: Comparison Table
Nine tests dominate the global English-testing landscape, and each is built for a different mix of academic, immigration, business, or professional-licensing use cases — from IELTS and TOEFL’s broad academic acceptance to OET’s healthcare focus and EIKEN’s dominance inside Japan.

Fees, score requirements, and acceptance policies change frequently — always confirm current details directly with the official test provider before registering.
IELTS
IELTS (International English Language Testing System) is jointly managed by the British Council, IDP, and Cambridge Assessment English, and it remains the most widely recognized proficiency test worldwide, with two versions — Academic and General Training — serving different purposes and audiences.
Academic vs. General Training
- IELTS Academic is for university admission and professional registration.
- IELTS General Training is for immigration, work, and secondary education purposes, particularly for UK, Canada, and Australia visa pathways.
Format: Four sections — Listening, Reading, Writing, Speaking — taken either on paper or by computer. Speaking is conducted face-to-face with a certified examiner (a feature that distinguishes it from AI-scored tests like PTE).
Scoring: Each section is scored on a band scale of 0–9, and an Overall Band Score is calculated as the average, rounded to the nearest half band.
Best for: Applicants targeting UK, Australian, and Canadian universities or immigration pathways, and anyone who prefers a live speaking interview over a computer-recorded one.
Countries accepting IELTS: The UK, Australia, Canada, New Zealand, and the USA, along with thousands of institutions in over 140 countries.
Related resource: see our IELTS preparation guide for band-by-band strategies and our English grammar lessons to strengthen the Writing and Speaking sections.
TOEFL
TOEFL iBT (Test of English as a Foreign Language, internet-Based Test), administered by ETS, is the most established academic English test in the United States and remains strongly preferred by North American universities for admissions decisions.
iBT format: Fully computer-delivered, testing Reading, Listening, Speaking, and Writing in an academic-lecture-and-classroom-discussion style that closely simulates university coursework.
Sections: Reading (academic passages), Listening (lectures and conversations), Speaking (independent and integrated tasks), Writing (integrated and independent essays).
Scores: Total score ranges from 0 to 120, combining four section scores of up to 30 points each.
Universities accepting TOEFL: Thousands of institutions across the USA, Canada, and beyond; it remains the safest default for applicants targeting US graduate and undergraduate programs.
Related resource: our TOEFL preparation resources break down each section with timing strategies and sample integrated-writing responses.
PTE Academic
PTE Academic (Pearson Test of English Academic) is a fully computer-delivered test that uses AI-based scoring across all four skills, which appeals to candidates who want fast, algorithmically consistent results without a live examiner.
AI scoring: Speaking and Writing responses are scored by automated systems, removing human-examiner variability and, according to Pearson, improving scoring consistency.
Fast results: Typically delivered within a few business days, faster than the average turnaround for IELTS or TOEFL.
Accepted countries: Strong recognition in Australia, the UK, and New Zealand for both study and immigration purposes, with growing acceptance in the United States.
Advantages: Single-sitting, single-format test (no paper option), quick results, and a test format many candidates find more predictable because of its automated scoring.
Related resource: our PTE Academic guide walks through the AI-scoring pattern recognition strategies that help with Speaking and Writing tasks.
Duolingo English Test
The Duolingo English Test (DET) is a fully online, adaptive proficiency test taken from home, and it has grown rapidly since 2019 to become one of the most affordable and widely accepted alternatives to traditional in-person testing.
Online format: An adaptive 45-minute core section (questions adjust in difficulty based on responses), followed by an unscored video interview and writing sample that are sent to institutions alongside the score.
Cost: Substantially lower than IELTS, TOEFL, or PTE, making it one of the most budget-friendly options among major proficiency tests.
Acceptance: Recognized by thousands of universities and programs across dozens of countries, though acceptance still varies significantly by institution and by visa or immigration authority.
Pros: Fast results (often within 48 hours), take it from home, lower cost, retake flexibility.
Limitations: Not accepted by every immigration authority or university (particularly some highly selective or government-run programs), and it carries less brand recognition among older or more traditional institutions than IELTS or TOEFL.
Always verify with your specific university or visa authority whether the Duolingo English Test is accepted before registering — acceptance policies vary and change over time.
Cambridge English Qualifications
Cambridge English Qualifications are exams developed by Cambridge Assessment English, distinguished by a unique feature among major proficiency tests: the certificates do not expire, offering a permanent, one-time credential rather than a score that must be periodically renewed.
B2 First (FCE): Certifies the B2 CEFR level — independent, everyday English for work, study, and travel. The most widely taken Cambridge exam.
C1 Advanced (CAE): Certifies the C1 level, commonly required by UK universities and employers for postgraduate study and professional roles.
C2 Proficiency (CPE): The highest Cambridge qualification, certifying near-native mastery of English.
Lifetime validity: Unlike IELTS, TOEFL, PTE, or Duolingo (all valid for two years), Cambridge certificates remain valid indefinitely once earned, though institutions may still ask for a recent score if language use has lapsed.
Related resource: browse our Cambridge English exam resources for level-specific study plans.
TOEIC
TOEIC (Test of English for International Communication), also from ETS, focuses on workplace and business English rather than academic contexts, and it is widely used by employers — especially across Asia — to benchmark staff and job-candidate communication skills.
Business English: Listening and Reading sections test workplace scenarios such as meetings, emails, and travel; optional Speaking and Writing modules assess professional communication tasks.
Jobs in Asia: TOEIC is especially common as a hiring and promotion benchmark in Japan, South Korea, and other Asian markets.
Companies accepting TOEIC: Many multinational corporations use TOEIC scores internally for hiring, promotion, or training-placement decisions rather than for university admissions.
EIKEN
EIKEN (jitsuyō eigo ginō kentei, “Test in Practical English Proficiency”) is Japan’s most established English test, administered domestically and used heavily for school, university, and employment purposes within Japan.
Popularity in Japan: EIKEN is deeply embedded in the Japanese education system, with many schools and universities referencing specific EIKEN grades in admissions and curriculum planning.
Different grades: The test uses a graded system from Grade 5 (beginner) through Grade 1 (advanced), with Pre-1 and Pre-2 intermediate steps, rather than a single continuous numeric scale.
University recognition: Many Japanese universities accept specific EIKEN grades as part of admissions or as an English-requirement waiver, though international recognition outside Japan is far more limited than IELTS or TOEFL.
CELPIP
CELPIP (Canadian English Language Proficiency Index Program) is a Canada-specific test used almost exclusively for Canadian immigration, citizenship, and some provincial licensing purposes, scored on a scale that aligns directly with Canadian Language Benchmarks (CLB).
It is only offered in Canada-relevant contexts (not typically used for university admissions outside Canada), and its close CLB alignment makes it a common choice for Express Entry and citizenship applicants who want their score to map directly onto Immigration, Refugees and Citizenship Canada’s requirements.
OET
OET (Occupational English Test) is designed specifically for healthcare professionals — including nurses, doctors, dentists, and other allied health workers — and uses profession-specific tasks (such as writing a referral letter) rather than generic academic content.
It is recognized by healthcare regulators in Australia, the UK, Ireland, New Zealand, and other countries, and it is often the preferred or required test for professional registration in these fields because its content mirrors real clinical communication tasks rather than general academic topics.
Which English Test Should You Choose?
The right English proficiency test depends less on which one is “hardest” or “easiest” and more on who is asking for your score — a university, an immigration authority, an employer, or a licensing board — since each of these audiences tends to prefer specific tests.
| Candidate Type | Recommended Test(s) | Why |
|---|---|---|
| International students (general) | IELTS Academic or TOEFL iBT | Broadest university acceptance worldwide |
| Budget-conscious students | Duolingo English Test | Lower cost, fast results, home-based |
| US/Canada graduate applicants | TOEFL iBT | Strong historical preference at North American universities |
| UK/Australia/NZ applicants | IELTS or PTE Academic | Strong regional recognition, SELT-approved (IELTS) |
| Workers (general corporate roles) | TOEIC | Business-English focus, common HR benchmark |
| Immigrants to Canada | CELPIP or IELTS General Training | Direct CLB alignment (CELPIP) or broad SELT acceptance (IELTS) |
| Nurses and healthcare professionals | OET | Profession-specific tasks accepted by health regulators |
| Engineers and technical professionals | IELTS, TOEFL, or PTE | Depends on target country’s licensing/immigration body |
| Teachers seeking certification abroad | IELTS or Cambridge C1 Advanced | Widely required for teaching visas and certification |
| Pilots and aviation professionals | Test aligned with ICAO English Language Proficiency requirements (verify with civil aviation authority) | Aviation-specific regulatory requirement, distinct from academic tests |
| University applicants wanting a permanent credential | Cambridge B2 First / C1 Advanced / C2 Proficiency | Lifetime validity, no retesting needed |
Always check the exact test and minimum score required by your target institution, employer, or immigration authority — requirements differ even between departments at the same university.
English Proficiency Levels (CEFR)
The Common European Framework of Reference for Languages (CEFR) is the internationally recognized six-level scale — A1 through C2 — used to describe language ability, and most major English proficiency tests report an equivalent CEFR level alongside their own numeric score so results can be compared across different exams.
- A1 (Beginner): Can understand and use very basic phrases.
- A2 (Elementary): Can communicate in simple, routine situations.
- B1 (Intermediate): Can handle everyday matters and describe experiences.
- B2 (Upper Intermediate): Can interact fluently with native speakers on a wide range of topics.
- C1 (Advanced): Can use English flexibly for academic and professional purposes.
- C2 (Proficient): Near-native mastery across all contexts.
Approximate score equivalencies (always confirm current official mappings with each provider):
| CEFR Level | IELTS | TOEFL iBT | PTE Academic | Duolingo | Cambridge Exam | TOEIC (L&R) |
|---|---|---|---|---|---|---|
| A2 | 3.0–3.5 | — | 30–35 | 55–65 | A2 Key | 225–545 |
| B1 | 4.0–5.0 | 42–71 | 36–49 | 70–90 | B1 Preliminary | 550–780 |
| B2 | 5.5–6.5 | 72–94 | 50–64 | 95–120 | B2 First | 785–940 |
| C1 | 7.0–8.0 | 95–120 | 65–83 | 125–145 | C1 Advanced | 945–990 |
| C2 | 8.5–9.0 | (near max) | 84–90 | 150–160 | C2 Proficiency | (near max) |
These bands are commonly cited approximations, not official conversion charts from the test providers. Score equivalencies can shift as scoring systems are updated (as happened with Duolingo’s 2024 rescale), so verify current mappings on each provider’s official website before relying on them for an application.
English Proficiency Test Scores
Most proficiency tests share a similar logic: a “good” score sits around the upper-intermediate to advanced range, minimum requirements are set individually by each institution, and scores typically remain valid for two years — except Cambridge, which never expires.
- Good scores: For most competitive university programs, a “good” score is roughly equivalent to IELTS 6.5–7.0, TOEFL 90–100, PTE 65–75, or Duolingo 120–130.
- Minimum scores: Vary widely — undergraduate programs often set lower minimums than graduate or professional programs, and some departments (law, medicine, journalism) require higher scores than the university-wide baseline.
- Validity period: IELTS, TOEFL, PTE, Duolingo, TOEIC, CELPIP, and OET are generally valid for two years from the test date. Cambridge English Qualifications do not expire.
- Score reports: Most providers allow official score reports to be sent electronically to a limited number of institutions for free, with additional reports available for a fee.
How to Prepare for an English Proficiency Test
Reading: Practice skimming for gist and scanning for specific details; time yourself against real test-length passages.
Listening: Expose yourself daily to varied English accents (British, American, Australian) through podcasts, news broadcasts, and academic lectures.
Speaking: Record yourself answering timed prompts, then review for fluency, pronunciation, and coherence rather than just grammar.
Writing: Learn the specific essay or task structures each test rewards — TOEFL and IELTS integrated tasks differ meaningfully from PTE’s summarize-text or Duolingo’s open-ended prompts.
Vocabulary: Build topic-specific vocabulary (academic, workplace, everyday) rather than memorizing random word lists.
Grammar: Focus on the errors that most commonly appear in your own writing and speaking, not on exhaustive rule memorization.
Mock tests: Take full-length timed practice tests under real conditions at least two to three times before test day.
Time management: Practice pacing for each section individually — running out of time on Reading or Listening is one of the most common avoidable score losses.

Sample English Proficiency Test Questions
Reading (sample)
Passage excerpt: A short paragraph about renewable energy adoption in urban areas. Question: According to the passage, what is the main reason cities have been slow to adopt solar infrastructure? A) High installation costs B) Lack of public interest C) Zoning and regulatory barriers D) Limited sunlight in urban areas
Answer: C. The passage identifies regulatory and zoning obstacles as the central barrier, not cost or interest, which are mentioned only briefly as secondary factors.
Listening (sample)
Audio scenario: A university lecture on climate patterns. Question: What does the speaker say happens to ocean currents when polar ice melts? A) They speed up B) They stop completely C) They become less predictable D) They reverse direction
Answer: C. The lecturer explains that melting ice introduces freshwater that disrupts current salinity, making patterns less predictable — not reversed or halted.
Grammar (sample)
Question: Choose the correct sentence. A) “She have been working here since 2020.” B) “She has been working here since 2020.” C) “She has being working here since 2020.” D) “She had been work here since 2020.”
Answer: B. Present perfect continuous requires “has/have been” + verb-ing; “she” (third-person singular) takes “has,” ruling out A and D, while C misuses “being” instead of “been.”
Vocabulary (sample)
Question: Choose the word closest in meaning to “meticulous.” A) Careless B) Thorough C) Hurried D) Confused
Answer: B. “Meticulous” means showing great attention to detail — closest to “thorough.”
Writing (sample prompt)
“Some people believe technology has made communication less personal. To what extent do you agree or disagree?”
Approach: State a clear position in the introduction, support it with two developed reasons and specific examples, address a counterargument briefly, and conclude by restating your view — aim for a structured five-paragraph response within the test’s time limit.
Speaking (sample prompt)
“Describe a skill you would like to learn. You should say: what it is, why you want to learn it, how you would learn it, and explain why this skill is important to you.”
Approach: Structure your answer chronologically or by category, use specific personal details rather than generalities, and practice speaking for the full allotted time (typically 1–2 minutes) without long pauses.

Common Mistakes Candidates Make
- Registering for a test without confirming the exact test and score their target institution requires
- Underestimating time management, especially in Reading and Listening sections
- Practicing only with unofficial materials that don’t reflect real test format or difficulty
- Ignoring speaking practice because it feels less “study-able” than grammar or vocabulary
- Waiting too long to register, resulting in a rushed preparation timeline or missed application deadlines
- Not checking score validity periods before submitting an application
- Assuming all tests are accepted everywhere without verifying with the specific university, employer, or immigration authority
