The magnitude of crime, violence, victimization, and associated disruption in the urban schools of the United States severely impairs the educational process and the normal psychological development of many students. The problems of urban schools result from the problems of the larger community, but the community also holds the solutions to violence and traumatic stress. Increased cooperation between the school and the community can be implemented through a variety of channels. Community and parent involvement in various forms is critical to violence prevention. Professional development for teachers can prepare them to address violence and the consequences of urban stress with their students while creating an educational environment that fosters conflict resolution. Any approach to the complex phenomenon of urban violence, victimization, and traumatic stress must be systemic. Enhancing psychological services, ensuring adequate nutrition, and providing a safe and caring environment will contribute to closing the achievement gap and relieving the effects of urban problems.
