This study examines the impact of evacuation drill training in formal schools in Thailand. We conducted a two-day training session on December 24 and 25, 2023, for 15 participants, including university professors and students, local government officers, and schoolteachers. This training focused on planning evacuation drills in schools. We distributed a questionnaire to participants to determine their understanding of the training content and its effects. The results indicated that the participants had acquired considerable knowledge and skills through the training, particularly in understanding the significance of evacuation planning in schools and imparting knowledge to students before disasters occur, based on the Japanese experience. These findings highlight the importance of learning concrete examples of natural disasters.
