Homicide Risk Assessment Tool
A specialized homicide risk assessment tool for mental health professionals — evaluate lethal violence risk factors and connect directly to intervention with the HSRA and three-part platform.
What Is a Homicide Risk Assessment Tool?
A homicide risk assessment tool is a structured, evidence-based instrument used by mental health professionals and threat assessment teams to evaluate the likelihood that an individual may engage in lethal violence. Unlike general mental health screeners or broad violence risk instruments, a dedicated homicide risk assessment tool focuses specifically on the risk factors and warning signs associated with homicidal behavior — including homicidal ideation, means access, historical violence patterns, and contextual stressors.
The HSRA (Homicide Safety Risk Assessment) is Homicide Zero's specialized homicide risk assessment tool, developed by a multidisciplinary team of clinical psychologists, behavioral threat assessment specialists, and school safety experts. The HSRA is purpose-built for targeted lethal violence evaluation — not a repurposed general risk screener — and is grounded in peer-reviewed threat assessment research.
What sets the HSRA apart from other homicide risk assessment tools is that it does not stop at a risk score. Each assessment result connects directly to the Safety Steps intervention module, which translates risk findings into specific, resource-matched actions — referral pathways, safety planning guidance, and monitoring protocols — so that identification leads immediately to intervention.
Many clinicians use general risk instruments — such as the HCR-20 V3 for broad violence risk or the SAVRY for adolescent populations — because no purpose-built homicide risk assessment tool previously existed for school and community mental health settings. The HSRA fills that gap: a validated, CE-accredited homicide risk assessment tool deployable by school psychologists, community clinicians, and threat assessment teams without requiring a forensic or hospital setting.
Three-Step Homicide Risk Assessment Platform
Our homicide risk assessment tool combines screening, comprehensive assessment, and intervention guidance in one integrated, evidence-based system.
Step 1: HTS
Homicide Threat Screener
A rapid 5-minute frontline screener to identify individuals who may need a comprehensive homicide risk assessment. Requires 30 minutes of online training (0.5 CE credit).
Step 2: HSRA
Homicide Safety Risk Assessment
The core homicide risk assessment tool. A comprehensive 20–30 minute assessment for licensed mental health professionals that evaluates risk across multiple domains and produces a structured risk profile. Requires 1 hour of training (1.0 CE credit).
Step 3: Safety Steps
Structured Intervention Guidance
Translates HSRA results into specific, resource-matched intervention actions — referral pathways, safety planning support, monitoring protocols, and family engagement guidance.
HSRA: What the Tool Evaluates
The HSRA homicide risk assessment tool evaluates risk across eight evidence-based domains, ensuring a comprehensive picture of lethal violence risk factors and protective factors.
Lethal Violence Focus
Specifically designed to assess homicide risk factors using evidence-based research on lethal violence patterns — not a general-purpose violence screener.
Professional Expertise Required
Designed for licensed mental health professionals with specialized training in homicide risk assessment methodologies. CE-accredited training available on demand.
Prevention-Focused, Not Just Scoring
Identifies modifiable risk factors and provides specific intervention recommendations via Safety Steps — moving directly from assessment to action.
HSRA Risk Domains
- Historical violence and prior homicide threats
- Clinical risk factors and current mental health status
- Contextual stressors and precipitating events
- Access to weapons and means assessment
- Protective factors and social support
- Treatment engagement and compliance
- Safety planning and risk management indicators
- Ongoing monitoring and reassessment protocols
Who Uses the Homicide Risk Assessment Tool?
Designed for the professionals most likely to encounter individuals in crisis — before violence occurs.
School Counselors
Use the HTS screener to evaluate students who display warning signs, and escalate to the HSRA homicide risk assessment tool when a deeper evaluation is warranted. Integrates with existing threat assessment team protocols.
Mental Health Professionals
Licensed clinicians use the HSRA for comprehensive evaluation of clients presenting with homicidal ideation. The structured format supports documentation, clinical decision-making, and defensible intervention planning.
Threat Assessment Teams
Multidisciplinary teams use the full HTS → HSRA → Safety Steps workflow to standardize evaluation, reduce subjectivity, and ensure every case receives consistent, documented homicide risk assessment.
When to Use a Homicide Risk Assessment Tool
The HSRA is designed for situations where homicidal ideation or lethal violence risk is a specific concern — not as a universal intake screener.
Clinical Triggers for the HTS Screener
- Student or client expresses anger, grievance, or resentment toward a specific person or group
- Threats — direct, indirect, conditional, or veiled — are reported by peers, family, or staff
- Individual displays unusual interest in past mass violence events or perpetrators
- Significant loss event (relationship, employment, status) coincides with behavioral changes
- Access to weapons is present or suspected alongside elevated agitation
- A prior threat assessment identified elevated concern and follow-up monitoring is warranted
Escalation Triggers for the HSRA
- HTS screener identifies elevated or high risk, warranting licensed clinician evaluation
- Client presents with active homicidal ideation in a clinical or school setting
- Multidisciplinary threat assessment team requires a structured evaluation for case documentation
- Situation involves a specific target, plan, or timeline
- Prior HSRA assessment identified risk factors that require structured reassessment
- Duty to warn or protect obligations are triggered and defensible documentation is required
Why a Specialized Homicide Risk Assessment Tool Matters
General violence risk instruments are calibrated to predict a broad range of violent outcomes — including assault, property destruction, and self-harm. When the specific concern is lethal violence or homicide, a purpose-built homicide risk assessment tool provides better signal by focusing on the distinct risk factors, warning sign patterns, and intervention pathways relevant to that outcome.
The HSRA does not replace general violence screeners where those are appropriate. It is the right tool when the clinical question is specifically: how likely is this individual to harm or kill another person, and what do we do about it?
General Violence Screeners (HCR-20, SAVRY)
Broad violence outcomes — assault, property, self-harm
Workplace Risk Tools (WAVR-21, SARA)
Workplace or domestic violence contexts
