Threat Assessment: Predicting and Preventing School Violence

Preventing school violence is a top priority for school and public safety officials today. Efforts include creating more positive school environments, establishing crisis response teams, increasing security measures, and improving school/community collaboration. Considerable energy also has been devoted to developing a process to identify students at-risk of becoming violent before they cause harm. Unfortunately there is no easy formula or "profile" of risk factors that accurately determines the "next school shooter." Most students who display multiple risk factors will never become violent offenders and some who pose a real threat will not demonstrate a prescribed level of risk. The use of profiling (i.e., ranking a student's behaviors and risk factors against a set of criteria) strongly increases the likelihood of misidentifying youngsters. Moreover, the process focuses solely on identification, not intervention, and fails to provide the necessary help to potential offenders.

A more viable approach is that of threat assessment, which uses a set of strategies or pathways to determine the credibility and seriousness of a threat and the likelihood that it will be carried out. Effective threat assessment must be conducted by a team of trained professionals as part of a comprehensive school safety program and with the support of all members of the school community (students, staff, parents, public safety). This process considers the full range of relevant factors and provides appropriate interventions for the potential offender(s).

Although there is no official model for threat assessment, experts in school crisis management, mental health, and public safety have identified common basic components of effective threat assessment procedures. The U.S. Secret Service and Federal Bureau of Investigation (FBI) have taken a leadership role in collecting data and developing recommended procedures and protocols. (Access full reports at and The following information can help schools establish a threat assessment process, but school officials also should review comprehensive recommendations and arrange for formal training of staff.

Understand the facts about school violence and potentially violent offenders.

It is important to avoid misperceptions about the prevalence and causes of school violence. Perhaps most critical to keep in mind is that no single factor leads to violence; multiple factors cause a person to become violent. All approaches to prevention and intervention, including threat assessment, should be based on what we actually know about the phenomenon. Secret Service and FBI findings include:

Establish a clear district-wide policy.

It is important to have specific, well-articulated procedures for exploring allegations of actual or potential violence. These matters require prompt, discrete, and responsible action on the part of school officials. The policy should include protocols for:

Build an interdisciplinary, trained threat assessment team.

Effective threat assessment is based on the combined efforts of a threat assessment team, usually composed of trained school-based personnel and select members of the broader school community such as law enforcement, faith leaders, and representatives of social service agencies. School personnel should include top administrators, mental health professionals, and security staff. The interdisciplinary team approach improves the efficiency and scope of the assessment process, (which can be time-consuming), provides diverse professional input, and minimizes the risk of observer bias. Specific training for all members of the team is essential! The Secret Service now offers training on preventing incidents of targeted violence, responding to threatening situations, and creating safe school climates.

Create a climate of trust between students and adults.

Students often know of potential problems well in advance of adults. They need to feel comfortable telling a trusted adult about concerns they have regarding threats of violence of any kind. Parents and community leaders should be incorporated as part of the supportive and trusted school/community environment. Students, staff, and parents should understand the following:

Assess the threat's type and level of risk.

"All threats are not created equal." A threat is an expression of intent to do harm or act out violently against someone or something. It can be spoken, written or symbolic. But many students who make a threat will never carry it out and, conversely, others who pose a real threat never make one first. There are a number of different types of threats and levels of risk. According the FBI, these include:

1. Types of Threats

2. Levels of Risk

Low Level of Threat

Medium Level of Threat

High Level of Threat

Consider all factors shaping the student's decision-making and behavior.

Threat assessment done correctly entails a deliberate and focused process for examining all relevant information, such as the student's personal history, relationships at home and school, recent life events, resiliency and coping style, etc. It is important to remember that you probably know less about the potential offender than you think and to try to view information through the student's eyes. The FBI has proposed a Four-Pronged Assessment Model that examines:

1. Personality of the Student

2. School Dynamics

3. Social Dynamics

4. Family Dynamics

Determine and implement interventions in a timely manner.

Specific procedures should be established in advance. Once the initial assessment has taken place, the team must decide the appropriate next steps. Interventions may need to be staged (e.g., immediately bringing the student in question under adult supervision versus recommending mental health counseling). Considerations should include whether or not the student can stay in school, what alternatives may be needed, when and how to notify parents, when and if to contact law enforcement, and what mental health, social service, and school-based interventions are needed to reduce/eliminate the student's risk of becoming violent.

Provide supportive interventions to potential offenders.

The goal of threat assessment is not only to keep schools safe, but also to help potential offenders overcome the underlying sources of their anger or hopelessness. Effective threat assessment provides adults useful information about a student's risks and personal resources. In most cases students will not carry out their threat, but may still be crying out for help. The assessment process should incorporate referral to appropriate mental health and social services, as well as a system for following up on the effectiveness of interventions. Among the other potential risks that can be identified and prevented are suicide, alcohol and drug use, physical abuse, dropping out, and criminal activity.

Although there is no way to guarantee eliminating school violence, a comprehensive interventions-based approach can greatly minimize the risk to both the potential victims and perpetrators. Threat assessment must be an integral part of a system that fosters a positive school environment; trust between students and adults; respect for others; intolerance for violence of any kind; collaboration between home, school, and community; and the belief that everyone can build toward their strengths given the appropriate support.
