This study was designed to identify high school administrators' level of using scientific problem-solving techniques in organisational problems based on inspectors' views. The population of the study was the inspectors working in the city of Kirklareli in 2014-2015 school year. No sampling method was used since the whole population was reached within the study. Survey model was adopted, and the "Scale of School Administrators' Level of Using Scientific Problem-Solving Processes and Techniques in Organisational Problems" developed by Sagir and Göksoy (2011: 1-11) in 5-point Likert type was used as the data-gathering instrument. The scale was adapted to the Kirklareli sample and the Cronbach's Alpha coefficient was 0,95. According to the findings, the inspectors stated that school administrators differed in their level of using scientific problem solving techniques in terms of various variables. In overall, the inspectors indicated that school administrators properly defined the organisational problems they encountered, but did not apply the solutions developed to solve these problems. The study suggests that in-service training should be organised to enable administrators to use the necessary techniques to solve organisational problems, and policies including requiring them to do a master's degree in areas that focus on these issues should be developed to enhance administrator effectiveness.
