Denmark is one of the countries that, year after year, leads the rankings in student competency, with an education system that is characterized by being completely free from primary school to university, and which differs significantly from the teaching system in Catalonia. Carolina Diarte (46 years old, born in Castellar del Vallès), knows this well. She has lived in the Scandinavian country for 18 years, where she has worked as a secondary school teacher for 15 years. She didn't expect to end up teaching in a high school in Denmark, but after meeting her Danish partner in Japan, they decided to live together in Copenhagen. Carolina had studied translation and interpreting in Barcelona, ​​​​which helped her find work as a teacher.
