Long before Columbine, many incidents of violence had made it clear that schools could benefit from improved assessment tools.
The development of MOSAIC for Threats by Students (MAST) included an exploration into the pre-incident indicators of explosive school violence. The process recognized established knowledge and research, and also advanced thinking in this area by drawing on more than two hundred experts and practitioners from the fields of education, counseling, psychology, parenting, threat assessment, law enforcement, and the judiciary. Even students participated in the development of MAST.
Most often, MAST is used by school administrators, counselors, and security/law enforcement officers.
