During the war at least 11 students were killed by the Germans. When most of Poznań was seized by the Red Army yet with the German troops still holding out in the Citadel, some teachers approached the nascent Polish administration about re-opening of the school; few days later the Młyńska premises were almost entirely destroyed during the final phase of the battle. An attempt to seize a non-school building still standing on the former Luisenschule plot proved unsuccessful. Following a brief period when the school operated jointly with the Potocka College and once a formal decision to re-open the school had been adopted, recruitment took place in the former Chamber of Commerce building. In 1945-1948 Dąbrówka was hosted in premises of Państwowe Liceum Pedagogiczne, and the former Colegium Marianum. The school commenced the schooling year of 1948/49 at , in the premises taken over from another college, shut down as hotbed of reactionary education. At that time the heavily damaged building at Młyńska Street was refurbished and turned into a dormitory for non-resident girls of Poznań colleges.
