Purpose: The purpose of this study is to verify differences arising from different educational backgrounds and employment paths in order to maintain performance capability and establish an effective management system through personnel management of security police, which is one of the job stress factors of the police related to human disasters. Method: In this study, among police officers in the security department as of 2020 who had experience in work related North Korean defectors, 100 trainees in the Police Human Resources Development Institute were surveyed via self-administration method. Among the collected survey questionnaires, 91 were selected as valid samples, excluding those whose answers were incomplete or missing. Results: As a result of the study, differences arising from different educational backgrounds showed a significant difference with a significance level of 5% in Q-2 and Q-8. The difference in stress depending on the employment path was significant with a significance level of 5% in Q-1, Q-3, Q-4, Q-5, Q-6, Q-7, Q-10, and Q-11. Conclusion: When assigning works to individuals according to their educational background, the works assigned to those with a low level of education should not conflict with each other, and the work environment should be improved to relieve the burden of excessive responsibilities for those with a high level of education. In addition, the analysis on the differences arising from different employment paths suggests that the stress of conflicting works for security police officers who have been employed through special recruitment needs to be relieved, and improvements should be made to reduce the stress of high responsibility and excessive workload for those who became a security police officer as a cadet.
