Duolingo English Test (DET) Preparation, Practice, and Institutional Use Syllabus

What should you look for when reviewing your DET writing samples?

Spelling, punctuation, grammar, response length, relevance to the prompt, and clear organization.

Name a common proctoring rule violation that can invalidate a DET result.

Looking away from the screen, having another person or device present, speaking to someone, or leaving the camera frame.

Why must you keep your face and eyes on the screen during the DET?

AI proctoring flags looking away as a possible rule violation, which can cause your test to be rejected and not certified.

List three behaviors that trigger DET proctoring violations.

Using notes or another device, having background noise/voices, and moving out of the camera view or covering your face.

What is the consequence of a confirmed DET proctoring rule violation?

The test session can be rejected, leaving you without a valid score and requiring a retake.

What is the mistake of 'underusing preparation time on open tasks'?

Beginning to respond immediately without using the allotted planning/prep seconds to organize ideas, leading to disorganized or short answers.

How should you use the preparation time given before an open-ended DET task?

Quickly plan your main points and structure so your response is organized, on-topic, and uses the full response time.

Why do spelling and punctuation errors matter on DET dictation and writing tasks?

Accuracy is scored, so misspellings and missing punctuation directly lower your Literacy and Production-related subscores.

What is the DET dictation task and what must you produce accurately?

You listen to a spoken sentence (replayable a limited number of times) and type it exactly, with correct spelling, capitalization, and punctuation.

What is a key strategy to avoid dictation errors on the DET?

Use the limited replays to catch every word, then proofread for spelling, capitalization, and punctuation before submitting.

What is the danger of 'going silent or under-length' on DET speaking tasks?

Long pauses or responses that are too short give the scoring engine too little speech to evaluate, lowering your Speaking/Conversation and Production scores.

How long should you aim to speak on open DET speaking prompts?

Keep talking for the full available time, avoiding silence; provide enough developed content to demonstrate range and fluency.

What should you do if you run out of ideas mid-answer on a DET speaking task?

Keep speaking by adding examples, reasons, or restating points rather than going silent, since silence is penalized.

How do you find an institution's required minimum DET score?

Check the specific college/program's admissions or international applicant page, or Duolingo's institution directory, for its accepted minimum DET score.

Why can a single DET score be acceptable at one school but not another?

Each institution and program sets its own minimum required score, so the same score may meet one school's bar and fall short at another.

On the DET's 10-160 scale, what is a common general undergraduate admissions range?

Many universities require roughly 105-120, but you must confirm each institution's exact minimum since requirements vary.

What is the DET score scale range?

10 to 160, reported in 5-point increments.

How many institutions can you send your DET results to, and at what cost?

You can send your certified results to an unlimited number of institutions for free.

How does free unlimited DET score sending compare with traditional tests like TOEFL/IELTS?

DET lets you send results to as many institutions as you want at no extra cost, whereas TOEFL/IELTS often charge per additional score report.

After completing the DET, how are results delivered to institutions?

Once certified (within about 2 days), you select institutions from Duolingo's portal and your results are sent to them electronically for free.

Roughly how long after taking the DET are certified results available?

Typically within 2 days (48 hours) of completing the test.

Why is the DET score only one part of a US college application?

Admissions also weigh transcripts/GPA, essays, recommendations, standardized tests, and other requirements, so a passing DET score alone does not guarantee admission.

What should you combine with your DET score when applying to US colleges?

Meet all other application requirements—application form, transcripts, essays, recommendations, deadlines, and any required standardized tests—alongside the DET score.

Before relying on the DET for admission, what must you verify about a target school?

That the institution accepts the DET for English proficiency and what minimum score it requires for your program.

How should you set a DET target score for your applications?

Set it to meet or exceed the highest minimum among all schools you are applying to, then prepare to clear that bar.

What is an effective feedback loop for DET prep using practice tests?

Take a baseline practice test, identify the weakest subscore, practice that area, then retake a practice test to measure improvement before the real exam.

Why retake the official practice test during preparation, not just once?

Periodic practice tests track progress, confirm whether weak subscores are improving, and gauge readiness for your target score.

What environment preparation reduces proctoring-violation risk on test day?

A quiet, well-lit private room, clear desk with no notes or extra devices, working camera/mic, and no other people present.

Compared to taking the test cold, what does full-length simulation primarily build?

Test stamina and time-management instincts, so you can sustain focus and pacing across the entire ~1-hour adaptive exam.

What is the best practice for the writing tasks regarding length and time?

Use the full response time and meet/exceed expected length with relevant, well-organized, error-checked content rather than stopping early.
