The school year ends and the closest horizon for students is the summer holidays, but a little further ahead, as the calendar progresses, there is the start of a new school year in September and meeting up with friends again. Taking a step forward and, in some cases, changing stages. But there are a few students for whom these holidays will only be the prelude to Groundhog Day, as they finish the school year knowing that the next one they will return to the same classroom, the same subjects, the same teachers, but with different classmates. While, years ago, it was a reality that was rarely questioned, now many variables are considered before making a student repeat a year. In fact, in Catalonia, it is only applied in studied and exceptional cases and when it has been proven to be the most beneficial option for the student.
