It's July, but classes haven't ended for everyone. There are 143 secondary school students from Barcelona (and their teachers) who, defying the temperatures, have extended the school year for three extra weeks to do an intensive Catalan course. After last year's pilot program, this summer the Barcelona Education Consortium has expanded the initiative with seven groups of about twenty students between 12 and 16 years old, most of whom need to consolidate their B1 Catalan level. They are all young people who have arrived in the city in the last year, mostly from Latin America but also from Morocco, China, Pakistan, or Ukraine. During the school year, they have attended one of the ten accelerated welcome classrooms (AAA) in Barcelona's high schools. Unlike the 238 ordinary welcome classrooms in public and private schools, the AAAs are designed for newly arrived secondary students to have an intensive immersion in Catalan for four months before joining their assigned educational center.
