Brasília, capital city of Brazil has a group of public language centers called "Centros Interescolares de Línguas". They are 8 centers whose currriculum has only foreign languages - English, Spanish, French and Germany(in only one of them).
CIL schools offer 3 hour-classes each week to students of public schoos. They form groups of 25 students or less than that. Moreover, all the teaches have to pass a selection exam to teach in those schools.
Besides foreign languages, teachers are worried to follow the conccepts of global education and character education. Project Based learning is also one approach that is followed in those schools.
