This study aimed to examine the methods and content factors of training that affect the perception of human rights of principals in human rights education training for principals. To this end, the data surveyed on 201 principals who have received human rights education training were statistically analyzed. The contents of the survey included their human rights education training experience and human rights perception. Subareas related to the training method and training contents were set as independent variables. The principal’s human rights perception was used as a dependent variable, and “recognition of human rights education training effect” and “judgment on student human rights” were set as the subareas. In addition, sex, school level where they work, and whether to work in the student human rights ordinance area were set as the control variables. The results are as follows. First, both the principal’s recognition of human rights education training effect and judgment on student human rights were higher at a statistically significant level than those of teachers. Second, the factor of the human rights education training method that affects the principal’s human rights perception was whether he received human rights education training in the previous year, that is, at the time of human rights education training. Considering this, it is necessary to determine ways to implement human rights education training for principals every year. Third, the content of human rights education training that affects the principal’s human rights perception was not “the general human rights and teaching methods for human rights education” but “the respect of human rights of students, the human rights of the socially disadvantaged.” Considering this, it is necessary to devise a plan to systematize the training contents with a focus on student human rights in the composition of human rights education contents for principals.
