The research aims to identify the administrative transparency of school principals from the perspective of physical education teachers in Karbala Governorate. The experiment was conducted to apply the scale to a sample of (408) physical education teachers in middle, preparatory, and secondary schools for boys. The researchers used the descriptive approach with a survey method to suit the nature of the problem to be solved. The statistical package (SPSS) was used to extract the results of the arithmetic mean (Mean), standard deviation (Std-Deviation), and the statistical (t) test for two independent samples. The Spearman-Brown equation and the simple correlation coefficient (Pearson) were used. The result was the construction of a scale of administrative transparency among school principals in Karbala Governorate. The process of constructing the research scale is of great importance in revealing the administrative transparency of school principals, the motivation of physical education teachers, and the extent of their administrative interaction in managing the school and teaching sports in a proficient manner. The researchers recommend the necessity of formulating a future vision for the school based on administrative transparency practices to explore good opportunities and the reasons for the decline in students’ academic, athletic and psychological levels, which would enable it to support teachers’ motivation. The school administration must rely on the dimensions of administrative transparency (information, participation, accountability, work systems and procedures, communication, performance evaluation), to work on enhancing the school’s reputation, to contribute to shaping its future, conducting assessments of the risks surrounding it and monitoring the changes that affect its activities
