Duolingo English Test Structure 2025
The test is divided into three key sections. Here’s how it flows:

1. Introduction & Tech Setup (5–10 minutes)
Before the actual test starts, you’ll go through:

On-screen instructions and test rules

System compatibility checks (camera, microphone, internet)

Identity verification

Room scan to ensure exam integrity

2. Adaptive Test Section (45 minutes)
This is the heart of the test. The questions change in difficulty depending on how well you’re doing. That means no two tests are exactly alike.

Types of Questions You’ll Face:
Read and Complete: Fill in the missing words to complete a given text passage.

Read Aloud: Read short sentences clearly into your microphone

Listen and Type: Listen to a sentence and type what you hear

Listen and Select: Pick correct English words from a list of spoken words

Read and Select: Choose the real English words from a text list

Write About the Photo: Write a few sentences describing an image

Speak About the Photo: Verbally explain what's happening in a photo

Speak the Sentence: Repeat a sentence after listening to it

Extended Speaking Prompt: Speak on a topic for up to 90 seconds

Note: Each task has its own time limit, and you can’t skip or revisit any questions.

3. Writing & Speaking Samples (10 minutes)
These are unscored responses, but they are sent to institutions along with your score. They offer a glimpse into how effectively you can communicate in English.
Writing Sample: You’ll have 3 to 5 minutes to complete a brief written task.

Speaking Sample: Record a short spoken answer in 1–3 minutes
