About us

The CLS was founded in 1960 by Dr. Ivan Illich+ as a part of the “Centro Intercultural de Documentación”, better known as CIDOC. The school is one of Mexico’s oldest and most respected language institutes. Our teaching method facilitates rapid improvement in Spanish language skills regardless of the student’s current ability. Our approach is through total immersion and personalized attention.


Every member of the instructional staff is a native Spanish speaker who has received rigorous training in the teaching of Spanish as a foreign language from certified professionals. A number of staff members have been associated with the school since its inception. They have taught thousands of students.


The CLS is for all persons considering Spanish as a tool for studies, professional activities, and travel. We welcome students from all walks of life. Anyone with a desire to develop fluency in Spanish can do so in a surprisingly short period of time!
