The International Centre for Languages ​​(CIDL) adopts the Common European Framework of Reference for Languages ​​(CEFR). Designed by the Council of Europe, the CEFR has become a global reference due to its clarity, adaptability and usefulness in assessing and standardizing language skills. It is divided into six levels, from A1 (beginner) to C2 (proficiency), each specifying comprehension, oral expression and writing skills.

Here is an overview of the six CEFR levels and their main characteristics:

1. A1 (Beginner): Ability to understand and use basic everyday expressions and simple sentences to meet practical needs. The learner can introduce him/herself and ask simple personal questions.

2. A2 (Elementary): Ability to communicate in everyday and simple situations. The learner can discuss familiar topics and express basic needs.

3. B1 (Intermediate): Sufficient competence to understand the main points of familiar topics and manage everyday situations encountered in travel or work contexts.

4. B2 (Advanced Intermediate): Ability to understand the complex content of technical or specialized texts, and to interact with a certain degree of ease in spontaneous conversations.

5. C1 (Advanced): Competence to use the language effectively for complex professional, academic, or social needs. The learner can understand long texts and express his or her ideas in a fluent and structured manner.

6. C2 (Proficiency): Highest level, where the learner is able to effortlessly understand any type of text or conversation, even subtle ones, and to express his or her ideas accurately in complex situations.
