Duolingo English Test (DET): The Modern Path to Global Education

The Duolingo English Test (DET) is a modern, digital-first English proficiency assessment designed for today’s international students and institutions. Recognized by over 5,000 programs worldwide—including top universities in the USA, Canada, UK, and Australia—the DET offers a fast, affordable, and convenient alternative to traditional exams. At E-Planet, we provide the specialized technical and linguistic training required to excel in this unique AI-adaptive testing environment.

What is the Duolingo English Test?

The DET is a computer-adaptive test that can be taken online, on-demand, from your own home. It measures your English proficiency in four subscores: Literacy, Conversation, Comprehension, and Production. The test is unique because the difficulty of the questions adjusts in real-time based on your performance.

Why Choose E-Planet for Duolingo Prep?

While the DET is convenient, its fast-paced and adaptive nature requires a specific set of strategies. Our program includes:

• Adaptive Mock Exams: We provide access to practice platforms that mimic the Duolingo algorithm, helping you get used to the increasing difficulty of the questions.
• Production & Conversation Labs: The DET heavily weights your ability to speak and write at length. We provide templates and drills for “Write about the Photo” and “Speaking Sample” tasks.
• Typing & Technical Speed: Since the test is fast, we help students improve their typing speed and computer literacy to ensure no time is wasted.
• Video Interview Coaching: We prepare you for the ungraded video interview portion, which is sent to universities alongside your score to showcase your personality.
• Result Analysis: Our trainers review your practice subscores to identify exactly which area (e.g., “Production”) is pulling your overall score down.

DET Test Format & Key Features

The test takes approximately 1 hour and consists of three main parts:

Section	Task Description	Duration
