In this research, it is aimed to examine the studies that deal with the problems encountered in course inspections in schools in Turkey with the method of meta-synthesis. This method provides the researcher with the opportunity to evaluate and synthesize the findings of the studies conducted with the qualitative method on the research subject. In meta-synthesis, the findings of the studies produced on a specific subject are brought together and analyzed in depth, synthesized and interpreted. The studies included in the research were reached by scanning the YÖK National Thesis Center, Dergipark, Google Scholar databases. As a result of the screening, 36 qualitative studies suitable for the research purpose and inclusion criteria were accepted as data sources. The research was carried out by following the meta-synthesis steps developed by Walsh and Downe (2005). As a result of the in-depth analysis and reinterpretation of the data obtained, the main themes related to the problems identified in the research were determined as the problems encountered before the course supervision, the problems encountered during the course supervision, the problems encountered after the course supervision, the problems experienced about the effectiveness of the supervision, and the problems originating from the individual and the organization. The problems encountered before the course supervision were divided into three sub-themes: lack of information and guidance, not meeting with the teacher, and planning problems. The problems encountered after the lesson supervision are in two sub-themes, the negative effects of supervision on teachers and the violation of confidentiality, the problems experienced in the effectiveness of supervision are in two sub-themes, the lack of effective supervision and the uncertainty of the purpose, function and standards of the supervision, and the individual and organizational problems originate from the supervisor. The problems were discussed in three sub-themes: problems arising from teachers and organizational problems. At the end of the research, solution suggestions were made for these problems.
