Professional development in crisis intervention skills can help address the growing needs of schools to train faculty to respond to students in acute crisis. Unlike traditional methods of classroom management, crisis intervention training teaches specific strategies to de-escalate conflict while at the same time addressing the underlying developmental, emotional and social needs of youth. The purpose of this study was to evaluate the impact of crisis intervention training and implementation on the thoughts, emotions and behaviours of educators. Using both quantitative and qualitative data, results suggest that training and implementation decreases negative attributions directed at the family, decreases negative emotional reactions, increases the desire to help students in crisis, and decreases student referrals out of the classroom. Implications for continuing professional development are discussed. (Contains 4 tables.)
