In this study, it was aimed to determine the views of the education inspectors about the in-service training (IST) they attended and the problems they experience during IST. Quantitative and qualitative design were used together in the study. The data were collected through the In-Service Training Assessment Scale (ISTA) and an open-ended questionnaire. The data obtained from 300 education inspectors who filled in the scale (working at 10 cities) and from 100 education inspectors among them who answered open-ended questions were evaluated. According to the results of the research, while the inspectors stated at "A Little" level, their IST needs have been determined, IST has been planned, the activities of IST have been evaluated and their IST needs have been met, they agreed "Moderately" that running process of IST is effective. The views of the education inspector differed in terms of age and graduation variables. Findings from qualitative research parallel with findings from quantitative data. Educational inspectors pointed out problems about the suitability of the course centers, utility of IST activities, the activities of the Ministry of National Education (MNE), the teaching staff in these activities and the number of IST. According to the results of the research, it could be said that the IST studies on education inspectors were not sufficient. [Paper presented at EYFOR (7th).]
