In 2019, the United States Secret Service released an analysis of targeted school violence, concluding the best practice for prevention was forming a "multidisciplinary threat assessment team, in conjunction with the appropriate policies, tools, and training". An earlier report published in 2018 concluded there was no single profile of a student attacker, and emphasized the importance of the threat assessment process instead. The threat assessment process described includes gathering information about student behaviors, negative or stressful events, and what resources are available for the student to overcome those challenges.
