Universities in Germany show an increasing need for specific information on professional demands encountered and addressed by graduates training to become teachers. To provide information on demands and abilities in teaching graduates, a specialised teacher module was developed in the framework of the German Cooperation Project for Graduate Tracer Studies (KOAB, INCHER Kassel). The scale operationalises a model of teacher action based on guidelines published by the Standing Conference of the Ministers of Education (KMK 2004; 2000). To test validity of the 40-item-strong scale, a confirmatory factor analysis (CFA, AMOS) was conducted. Analyses are based on a sample of 937 teachers in training who graduated from the universities of Cologne and Münster, North Rhine-Westphalia, between 1 October 2007 and 30 September 2008. Overall, the results of the first analyses emphasise the scale's potential to provide insight into the demands for which students should be prepared by their teaching studies.
