In an effort to promote the social and cognitive competence of youth, school psychologists must be prepared to address a multitude of contextual factors and life events that impact children's performance and adjustment in school and subsequent developmental trajectories. The domain of crisis preparedness and intervention has received increased attention during the past decade (as evidenced by a growing school crisis intervention literature) and is currently a training standard for school psychologists in some parts of the world. Crisis situations may emerge following natural disasters such as floods, fires, tornadoes or earthquakes and also from human generated situations such as bombings and school shootings. Each of these events is likely to affect the children and families in schools and communities by presenting them with problems that will be challenging to cope with. There are a variety of crisis preparedness and intervention models and strategies available to address crisis situations. Without a shared foundation for crisis intervention, responding to crisis situations may be further complicated, especially in situations where international colleagues are collaborating. Therefore, a shared foundation that includes both preparedness and intervention while emphasizing both developmental and school considerations will be invaluable in our efforts to facilitate collaboration among diverse colleagues across multiple contexts. The purpose of this article is to incorporate several models and frameworks in order to provide a shared foundation for school psychologists and other educational and mental health professionals regarding crisis preparedness and intervention. To establish a shared foundation for international crisis collaboration, it is also necessary to review the original works discussed in this brief overview and participate in relevant workshops.
