Duolingo English Test Score Chart: DET vs IELTS vs TOEFL

The Duolingo English Test (DET) has become a mainstream option for students who need an English proficiency score for university admissions. At the same time, IELTS and TOEFL remain the most widely recognized “traditional” tests around the world. Because these exams use different formats and scoring scales, one of the most common questions is simple: How does a DET score compare to IELTS or TOEFL?

This guide explains how the three scoring systems work, provides a practical comparison chart (DET vs IELTS vs TOEFL), and shows how to interpret scores for typical university requirements. You’ll also learn why score comparisons are never perfectly “exact,” and how to use a chart correctly when you choose a test or set a target score.

Quick Overview: DET vs IELTS vs TOEFL (What’s Different?)

Before looking at numbers, it helps to understand why the scales differ. Each exam measures similar skills (reading, listening, speaking, writing), but they do it in different ways.

• DET (Duolingo English Test): Online, computer-adaptive, shorter test time, scored on a 10–160 scale. It also reports subscores (Literacy, Comprehension, Conversation, Production).
• IELTS Academic: Test-center based (with some official options varying by region), scored on a 0–9 band scale in 0.5 increments. Speaking is typically a live interview.
• TOEFL iBT: Computer-based, scored 0–120 (four sections usually 0–30 each). Focuses strongly on academic English tasks.

Because the formats and scoring models differ, any comparison chart should be treated as a practical equivalency for admissions planning, not a scientific conversion formula.

How DET Scoring Works (10–160) in Plain English

The DET score ranges from 10 to 160. The exam uses adaptive testing, meaning the difficulty of questions can change based on how you perform. The goal is to estimate your English proficiency efficiently.

In addition to the overall score, DET provides four subscores:

• Literacy: Reading + writing ability (understanding and producing written English)
• Comprehension: Listening + reading understanding
• Conversation: Speaking + listening for interaction
• Production: Speaking + writing output

Many universities focus primarily on the overall score, but some programs also check subscores (for example, a program may want strong Production for writing-heavy majors).

How IELTS Scoring Works (0–9 Band)

IELTS reports four section band scores (Listening, Reading, Writing, Speaking) and an overall band score. The overall band is calculated from the average of the four section scores and rounded to the nearest 0.5 band.

Examples:

• 6.0–6.5: Common minimum range for many undergraduate programs
• 7.0–7.5: Often required for more competitive universities or graduate programs
• 8.0+: Very strong proficiency, sometimes required for top programs

IELTS requirements vary by country, university, and major. Some schools also set minimum section scores (for example, “Overall 7.0 with no band less than 6.5”).

How TOEFL iBT Scoring Works (0–120)

TOEFL iBT scores are typically the sum of four sections (Reading, Listening, Speaking, Writing), each usually scored 0–30 for a total of 0–120.

Examples:

• 60–79: Basic to mid-level university entry in some contexts
• 80–99: Common minimum for many universities
• 100–110+: Competitive programs and top universities

Like IELTS, some universities require minimum section scores (for example, “Writing 22+”).

DET vs IELTS vs TOEFL Score Chart (Practical Comparison)

Below is a widely used comparison chart that students use to estimate equivalency across exams. Treat this as a planning tool for applications, not a guarantee. Individual universities may publish their own equivalency tables or accept one test but not another.

How to use this chart: Start with the score requirement listed by your university (often IELTS or TOEFL), then look across to estimate what DET score would be “in the same neighborhood.” If your school lists DET requirements directly, follow the official requirement instead of relying on any chart.

Common University Requirements (What Scores to Aim For)

Universities vary widely, but the patterns below are common for many English-taught programs. Always verify your target school’s official policy, especially if your department has stricter requirements than the university’s general admissions office.

• Many undergraduate programs: IELTS 6.0–6.5 / TOEFL 70–85 / DET 100–115
• Many graduate programs: IELTS 6.5–7.0 / TOEFL 85–100 / DET 115–125
• Highly competitive universities or programs: IELTS 7.0–7.5+ / TOEFL 100–110+ / DET 125–140+

Important: programs like nursing, education, law, medicine, and teacher training can require higher speaking/writing performance. In those cases, the overall score might not be enough; they may ask for minimum section scores (IELTS) or subscores (DET).

Why Score Comparisons Are Not Perfect (And What That Means)

It’s tempting to treat conversion charts like a calculator: “DET 120 equals IELTS 7.0.” In real life, comparisons are approximate because:

• Different test design: Adaptive tasks vs fixed sections can emphasize different strengths.
• Different speaking evaluation: IELTS uses a live examiner; TOEFL/DET record responses and score them with rubrics (and technology-assisted scoring in some cases).
• Different timing pressure: The style and speed of tasks can favor certain learners.
• Different scoring models: Band scores vs scaled scores vs proficiency estimates are not identical measurements.

So the best way to interpret equivalency is: “This score range is likely to meet a similar admissions threshold,” not “This is exactly the same proficiency.”

How to Choose the Right Test Using the Score Chart

Use the chart as part of a decision process:

1. Check acceptance first: Confirm your university (and department) accepts DET. Some schools accept DET for undergraduate but not graduate programs, or accept it only for certain intakes.
2. Check minimum scores: Look for overall score AND any section/subscore minimums.
3. Choose based on timeline: DET is popular for quick results; IELTS/TOEFL may take longer but are universally recognized.
4. Choose based on strengths: If you perform better in live speaking, IELTS might feel more natural. If you prefer computer-based tasks, TOEFL/DET may suit you.
5. Build a buffer: Aim above the minimum. If the minimum is DET 110, target 115–120 when possible.

A buffer matters because requirements can be strict and competitive. Also, some programs receive more applicants than spots, and they may prefer higher scores even when a minimum is published.

Example Conversions (Realistic Target Setting)

Here are practical examples of how students use a chart to plan:

• Case 1: A university asks for IELTS 6.5. Using the chart, you would typically target DET 110–115 or TOEFL 80–89. If the program is competitive, aim higher (DET 120).
• Case 2: A graduate program asks for TOEFL 100. The chart suggests DET around 120–130 or IELTS around 7.0–7.5. If the department is writing-heavy, you may want to push toward the upper end of that range.
• Case 3: You already have DET 105. That often aligns with IELTS around 6.0–6.5 or TOEFL around 75–79. Some universities will accept it, but many competitive programs may not.

The key is to match your score to your target school’s minimum, then add a margin if possible.

What About DET Subscores vs IELTS/TOEFL Section Scores?

This is where students often get confused. IELTS and TOEFL have clear sections. DET has subscores that combine skills. If a university states only an overall DET score requirement, you can focus primarily on the overall score. But if they mention subscores, you should plan accordingly.

Here is a simple way to think about it:

• If you need stronger writing: pay attention to Literacy and Production.
• If you need stronger speaking: pay attention to Conversation and Production.
• If you struggle with listening/reading comprehension: focus on Comprehension.

If your target program publishes IELTS requirements like “Writing 6.5+,” your DET plan should include improving the tasks that raise Production and Literacy, not just chasing the overall score.

Tips to Improve Your Score Efficiently (Based on the Chart)

If you’re using the chart to reach a target quickly, study strategy matters. Here are high-impact approaches:

• Practice timed responses: DET tasks often require quick speaking and writing. Train yourself to organize ideas fast.
• Build template language: For speaking prompts (opinion questions, describing images), prepare flexible phrases you can reuse naturally.
• Do dictation drills: Listening-and-typing style practice improves accuracy, spelling, and grammar at the same time.
• Fix “small mistakes” that cost points: Basic grammar errors, missing articles, verb tense problems, and unclear pronunciation can lower performance across tasks.
• Simulate test conditions: Quiet room, stable internet, clear microphone, and proper lighting reduce technical risk and stress.

Because admissions decisions can depend on crossing a minimum threshold, the most efficient preparation is often “targeted improvement.” Identify your weak area (speaking clarity, writing structure, listening accuracy) and train it daily.

Final Advice: Use the Chart, But Follow Your University’s Official Policy

A DET vs IELTS vs TOEFL score chart is extremely useful for planning and goal-setting, especially when you’re deciding which test to take or estimating whether your current score is competitive. But universities are the final authority. Always confirm:

• Which tests are accepted (DET / IELTS / TOEFL)
• Minimum overall score requirements
• Minimum section or subscore requirements (if any)
• Whether the requirement differs by program, campus, or intake

If your target school accepts DET and the requirement is within your reach, the Duolingo English Test can be a fast and cost-effective option. If your university requires IELTS or TOEFL specifically, the chart still helps you understand your current level and plan your next step. Either way, the smartest approach is to set a realistic target, add a buffer above the minimum, and prepare with the test format in mind.

FAQs (Frequently Asked Questions)

What is a good Duolingo English Test score for university admission?

A “good” Duolingo English Test (DET) score depends on the country, university, and program you are applying to. Many institutions set their minimum requirement somewhere around the 100–115 range, while competitive programs may expect 120–130 or higher. Some highly selective universities and graduate departments may look for scores in the 130–140+ range. Always prioritize the official requirement published by your target school, and aim a little above the minimum when possible. That extra buffer can help if a program is competitive or if certain departments have stricter language expectations than the general admissions office.

Is the DET score chart an official conversion from IELTS or TOEFL?

No. A DET vs IELTS vs TOEFL score chart is a practical comparison tool, not an official universal conversion. These exams use different formats, scoring models, and test tasks, so there is no perfect one-to-one conversion that applies to every situation. Some universities publish their own equivalency tables, and those should be treated as the most reliable reference for that specific institution. In general, use score charts for planning and goal-setting, then confirm requirements directly with your university or program.

Why do different websites show slightly different score comparison tables?

Small differences happen because comparisons are based on research, institutional policies, and real-world admissions use rather than a single standardized conversion formula. Universities may set their DET cutoffs based on their internal evaluation of applicants, and those cutoffs can change over time. In addition, some charts focus on minimum requirements, while others reflect “competitive” ranges. If you see minor variation between tables, focus on ranges instead of exact numbers, and rely on your target university’s official requirements whenever possible.

Do universities care about DET subscores or only the overall score?

Many universities focus mainly on the overall DET score, especially for general admissions screening. However, some programs may pay attention to subscores, particularly when communication skills are critical for academic success. For example, writing-intensive majors may care more about Literacy and Production, while programs that involve presentations or teamwork may care more about Conversation. If your target program lists subscore requirements (or expects strong performance in a specific skill), prepare with that in mind rather than only chasing a higher overall score.

Which test is easier: Duolingo English Test, IELTS, or TOEFL?

“Easier” depends on your strengths. The DET is shorter and can be taken at home, which many students find less stressful. IELTS includes a live speaking interview, which can feel easier for students who communicate well face-to-face, but harder for those who get nervous with an examiner. TOEFL is strongly academic and computer-based, which can suit students who are comfortable with university-style reading and listening tasks. The best choice is the test that is accepted by your target schools and matches your learning style and strengths.

How long are DET scores valid?

DET scores are generally valid for two years, similar to IELTS and TOEFL. Universities may require that your score is still valid at the time you apply, enroll, or submit final documents. Because policies can vary, it is smart to confirm the validity rules with your university, especially if you are applying to multiple intakes or planning a longer timeline before enrollment.

Can I use the DET for immigration or work visas?

In many cases, DET is primarily used for academic admissions rather than immigration. Some visa, licensing, and professional pathways require specific exams such as IELTS or TOEFL, and they may not accept DET. If your main purpose is immigration or a regulated profession, check the official requirements from the government or licensing authority. If your purpose is university admission, DET acceptance has expanded significantly, but you still need to confirm acceptance at your specific institution and program.

What if my target university accepts DET, but my department does not?

This situation can happen, especially for graduate programs or specialized departments. Universities sometimes have a general English proficiency policy, but individual faculties (such as business, education, nursing, or law) may set stricter rules. In that case, the department’s requirement usually takes priority for admission into that program. Always check both the university-level admissions page and the department or program page before choosing your test.

How can I raise my DET score quickly?

The fastest improvements usually come from targeted practice. If you struggle with listening accuracy, do daily dictation training and focus on spelling and grammar. If speaking is your weakness, practice timed responses and work on clarity, pace, and structure. For writing, focus on organizing ideas quickly and producing clean sentences under time pressure. Taking official practice tests and simulating test-day conditions can also help. Instead of studying everything equally, identify the skill area that holds your score back and work on it consistently.
