Course - The New Levels
The Common European Framework of Reference (CEFR, known as Marco Común in Spanish) establishes the following levels:
A2 corresponds to our Básico 1 y 2 (A2.1 and A2.2)
B1 corresponds to our Intermedio 1 y 2 (B1.1 and B1.2)
B2 corresponds to our Avanzado 1 y 2 (B2.1 and B2.2)
We hope to expand to C1 whenever it is possible
Here is the Global CEFR Scale sorted out by the different levels.
Here is a Self-Assessment Grid to give you an idea of what levels A1 to C2 are like in terms of the different skills.
Until we publish the guidelines for the new courses, you can check out:
