The general purpose of this study is to identify the target policies for in-service education in Turkey's main policy papers and documents of teacher training and development institutions, and to investigate reflections of these policies on practice. The study was based on historical research, which is one of the qualitative methods. The data were collected through document analysis and analyzed with content analysis. Regarding the research results, it was determined that target policies for in-service training activities in the field of teacher training in Turkey were offered within two main frameworks. When the reflections of these policies on practice were evaluated accordingly, it was revealed that putting policy theories into practice was generally achieved; however, some policies were offered as specific to several cities without being reflected across Turkey.
