This article describes the development, program evaluation, and future directions of the PREPaRE School Crisis Prevention and Intervention Training Curriculum (PREPaRE). Satisfaction ratings were analyzed for 1,073 participants who attended the Crisis Prevention and Preparedness workshop (Workshop 1) and 1,008 participants who attended the Crisis Intervention and Recovery workshop (Workshop 2). Results suggested high participant satisfaction. To assess the extent to which the curriculum achieved its objectives, analyses of pre- and posttest data were conducted for 1,212 Workshop 1 participants and 1,008 Workshop 2 participants. Results revealed significant improvements in crisis prevention and intervention attitudes and knowledge. A qualitative analysis of workshop evaluation comments indicated strengths regarding the content, workshop materials, and active learning components as well as areas to improve, such as reducing the quantity of information presented. Study limitations, as well as future directions for the PREPaRE curriculum's ongoing evaluation and development, are discussed. (Contains 5 tables.)
