School personnel help youth cope with life and school stressors. However, help may depend on each person’s confidence or knowledge of such issues. In 2019 and 2020, more than 13,800 Texas educators participated in Emotional Backpack Project (EBP) training to support youth coping with behavioral and mental health issues. Post-intervention results revealed significant gains in self-perceived understanding of students’ behavioral and mental health issues, improved confidence in approaching students, parents, or other school staff to discuss students’ harmful behaviors, understanding of mindfulness activities, and increased knowledge of trauma informed schools and trauma informed educators. Teachers and other school personnel were less confident in approaching parents or guardians to discuss youth mental health issues than in approaching students, counselors, and other staff. School personnel’s knowledge, perceptions, and confidence to help students cope with behavioral and mental health issues was significantly better after EBP interventions. EBP training should be adopted widely and occur more than once annually.
