The present research concentrates on written text competence of Russian-speaking adults between 24 and 33 years of age who come from Russia or the Ukraine. A text competence is defined here as an ability to write cohesive and coherent texts which are marked by an extensive and differentiated vocabulary. The work can be subdivided into three segments: report of the research state, reporting a theoretical part and the empirical research. In the research state, some studies are first introduced to the text competence in German as a second language as well as through some analysis of writing processes by German learning adults. Next segment presents a theoretical base that creates a scientific frame for the studies.In the final empiric part, the text competence of Russian-speaking adults is analyzed in German as a second language with the help of macrostructural and microstructural analysis of their texts and with the help of the indicators and is evaluated. First, text extent, text arrangement, subject development and text coherence of every single text are analyzed; in the second step, cohesion means, syntax complexity, linguistic correctness and variation are examined. Besides, it is recognized that written text competence of Russian-speaking adults can be trained in a different way. With the attempt to determine the influence of four factors mentioned above, the text competence is proved to be related to the duration of stay as well as professional education, and it has positive effect on the text quality in Austria and concerted German acquisition in the homeland. Also it is known that the text competence is directly connected to the vocabulary extent and to the influence of German Grammar. By the detailed macroanalyses and microstructural text analyses, the present investigation comes to the result that Russian-speaking adults, under certain conditions, are able to reach a high text competence level in German as a second language.
