Abstract: When reviewing the past post-disaster interventions, the researchers found that the role of teachers as a key factor in those interventions was not identified. Teachers as students' mentors and chaperons, they play a critical role in the reconstruction of post-disaster schools and the students' mental health. This research, therefore, situated in post-disaster schools in China, created a systematic post-disaster psychological intervention model for teacher training—a trauma intervention model of expert-coach- teacher collaboration. This model which integrated three factors of teacher as therapist (TAT), student assistance plan (SAP) and coaching as theoretical evidence to promote the teacher's ability of psychological counseling. It was proved that this model effectively promoted the long-term development of post-disaster psychological intervention and has been well applied in other post-disaster aid work, such as Yushu earthquake, Ya'an earthquake and Ludian earthquake. It is of great significance to the psychological health development of post-disaster teachers and students.
