What Are the CEFR Levels?

The CEFR categorizes language proficiency into six levels, each indicating a different degree of fluency and skill:

· A1 (Beginner): At this level, learners can understand and use basic expressions in everyday situations, introduce themselves, and ask and answer simple questions.

· A2 (Elementary): Learners can handle routine tasks and communicate about familiar topics, such as personal interests, daily routines, and travel.

· B1 (Intermediate): At this level, learners can discuss a wider range of topics, such as work, studies, and hobbies, and express ideas clearly in both spoken and written form.

· B2 (Upper-Intermediate): Learners can engage in more complex conversations, both socially and professionally, and produce well-organized texts on a variety of subjects.

· C1 (Advanced): At this level, learners can understand demanding texts, express themselves fluently and spontaneously, and use English effectively in academic, professional, and social contexts.

· C2 (Proficient): Learners at this level can understand almost everything heard or read, summarize information from different sources, and express themselves precisely and fluently.

How Do DET Scores Relate to CEFR Levels?

The Duolingo English Test is scored on a scale from 10 to 160, which corresponds to the CEFR levels as follows:

These score bands allow institutions to assess a test-taker’s proficiency and determine whether they meet the language requirements for various academic programs. For example, most undergraduate programs require a minimum of B2, while graduate-level programs often expect a C1 or higher.

How to Improve Your DET Score and Reach Higher CEFR Levels

Practice with Official Duolingo Resources: Make use of DET's official practice materials, which include sample questions and full-length practice tests that mirror the actual exam. This will familiarize you with the test format and help identify areas for improvement.

Target Weak Areas: Pay attention to which skills—whether it’s reading, writing, speaking, or listening—are holding you back, and dedicate more time to improving those specific areas.

Immerse Yourself in English: Enhance your language skills by engaging with English regularly. Watch English-language movies and TV shows, listen to podcasts, read books, and practice speaking with native speakers or language partners.

Set Realistic Goals: As you prepare for the test, set gradual milestones to help you progress through the CEFR levels. Start by aiming for a B1 score, then move toward B2, and continue working your way up.

The Duolingo English Test’s correlation with CEFR levels offers a clear and accessible way to gauge your English proficiency. Understanding these levels helps you track your progress, set achievable goals, and determine whether you’re ready for academic or professional opportunities. With consistent practice and the right resources, advancing from A1 to C2 is a reachable goal for any dedicated English learner.
