The Duolingo Test –

Aspect	IELTS	Duolingo
Sections	Listening, Reading, Writing, Speaking	Adaptive test covering Reading, Writing, Listening, Speaking
Listening	This section involves listening to recordings of native English speakers and answering questions. There are 4 sections, each increasing in difficulty.	Listening skills are tested throughout the adaptive test with various question types, such as identifying spoken words or phrases.
Reading	Includes three long texts that range from descriptive and factual to discursive and analytical. Questions include multiple-choice, matching, and short-answer questions.	Reading comprehension is assessed through the adaptive test, which consists of tasks like reading and understanding short and long texts, identifying missing words, and interpreting meaning.
Writing	Consists of two tasks. Task 1 requires writing a short essay based on a graph, table, chart, or diagram. Task 2 requires writing a formal essay in response to a point of view, argument, or problem.	Writing is integrated into the test with tasks that may include writing brief responses to prompts, completing sentences, and writing a short essay.
Speaking	Conducted as a separate part of the test, either face-to-face or via video call with a trained examiner. It involves a structured interview, a short speech, and a discussion.	Speaking tasks are included in the adaptive test, which has a video interview format. Test-takers respond to prompts by speaking into the computer's microphone.

What is the curriculum or syllabus for the Duolingo and IELTS tests? 

Speaking, writing, listening, and reading are the four fundamental language skills tested on both tests; however, the methods used to evaluate these abilities vary.

• Listening: Duolingo encourages test-takers to recognize the correct spoken words and transcribe audio recordings, whereas IELTS requires them to complete assignments based on recorded conversations or monologues.
• Writing: In an essay, IELTS test takers summarize visual data and address a point of view. On the other hand, the Duolingo practice test requires students to write a 500-word essay and fill in the blanks.
• Reading: Duolingo assessments concentrate on completing logical sentences and filling in missing words, whereas IELTS incorporates lengthy passages from novels and magazines.
• Speaking: Duolingo needs spoken responses recorded on the test site, whereas IELTS uses an in-person interview.
