Science Senator Ina Czyborra (SPD) pointed out the rising cost of living and the shortage of teachers in Berlin. The result is a high number of student teachers who work in schools during their studies. The Flex-Master should take the needs of students into account. Education Senator Katharina Günther-Wünsch (CDU) said that the Flex-Master would make teacher training more modern and flexible - and therefore more attractive for many young people who decide to become teachers. At a time when many students are already teaching in schools during their studies, it is important to better dovetail studies and practice.
