Our innovative system allows school administrators and authorized system admins to conduct threat assessments on subjects-of-concern, such as students, employees, and other individuals exhibiting threatening behaviors. The proprietary system uses a quantitative algorithm and analyzes qualitative data to determine apparent threat-level of the subject-of-concern. The system is based on violence prevention research related to the Comprehensive School Threat Assessment Guidelines (CSTAG), Columbia Suicide-Severity Rating Scale, FBI and U.S. Secret Service. School-based teams have access to the TAP App Assessment tools that address Bullying, Harassment, Self-Harm, Abuse, Targeted Violence, Insider Threats, Outsider Threats, and Title IX Incidents. Comprehensive reports are securely archived but can be accessed by authorized managers for revisions and updates. The system allows for data analytics and the ability to develop customized individual threat management plans.
