Resumen:
Knowing a foreign language is important in life, because through it, the individual becomes part of a globalized world and interacts effectively with the rest of the world, as well as accessing a culture and new knowledge. For this reason, learning a language has become a challenge in the lives of each person.
The Common European Framework of Reference is a way of describing the level of proficiency in a foreign language, hence it is not specifically linked to any specific language test, it is a collection of competency statements that lists the functions you will be able to perform a student, using a foreign language at a given proficiency level.
A foreign language teacher, whatever the language, can use these competency statements to assess and design lessons that address the student's unfamiliarity. This has replaced many of the levels used to validate students' language skills. That is why most of the educational systems, both in Europe and in Latin America, gradually advance towards the development of their objectives of commanding a foreign language based on the CEFR.
