A threat is an expression of intent to harm someone. Threats may be spoken, written, or expressed in some other way, such as through gestures. (Illegal possession of weapons are presumed to indicate a threat unless careful investigation reveals otherwise.) Threats may be direct or indirect and evaluated to be either transient or substantive.
Owen J. Roberts uses a defined model in all school buildings when responding to a Violent Threat. Each school has a team who is trained in prevention, conflict resolution, and evaluation. There are times when police may be called. The primary goal of threat assessment is to prevent violence including self harm and harm to others. In very serious substantive threat cases, a safety evaluation will be conducted and a safety plan will be developed, implemented and revised as needed. In some cases, a mental health assessment may be conducted.
