This study details a program evaluation of the "PREPaRE School Crisis Prevention and Intervention Training Curriculum" ("PREPaRE"), conducted in the United States and Canada between 2009 and 2011. Significant improvements in crisis prevention and intervention attitudes and knowledge were shown among 875 "Crisis Prevention and Preparedness" workshop (Workshop 1) participants and 1,422 "Crisis Intervention and Recovery" workshop (Workshop 2) participants on matched pre-tests and post-tests. Results indicated high participant satisfaction for both Workshop 1 and Workshop 2. A qualitative analysis of workshop evaluation comments indicated strengths regarding workshop aims, materials, and activities, as well as suggestions for improvement, such as utilizing more active learning components. The use of these findings in the "PREPaRE" curriculum revision is discussed.
