After completing secondary school,she transferred to the Evangelisches Gymnasium Hermannswerder near Potsdam,where she earned her Abitur (university entrance qualification) in 1978. However,this qualification was not recognized in the GDR as sufficient for general university studies. In 1981,she successfully took another Abitur examination at the Volkshochschule Berlin Mitte. Nevertheless,she was still not granted admission to a university. Beginning in 1982,she became active in the independent peace movement in the GDR,participating,among other groups,in Frauen für den Frieden.
Kibelka taught herself Polish and Lithuanian,traveled through Eastern Bloc countries,and worked in the administration department of the Aufbau-Verlag publishing house in Berlin. Between 1987 and 1990,she worked as a freelance translator and interpreter for Lithuanian and Polish.
