Our innovative system allows organizational managers 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 includes the Comprehensive Student Threat Assessment Guidelines (CSTAG), Columbia Suicide-Severity Rating Scale, and CLPS Bullying Assessment and Violence Prevention Questionnaires. 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.
