What CVI practitioners do—and how to get started.

A field introduction for aspiring and new outreach workers, violence interrupters, intervention specialists, and case managers. See how the roles fit together, explore five practice pathways, and learn what support to expect from an employer.

← All rolesOutreach workers · violence interrupters · intervention specialists · community violence intervention (CVI) teams

Start with the field

CVI is relationship work with a team behind it.

Community violence intervention (CVI) works with people and places facing a high risk of violence. Trained workers build trust, help interrupt immediate harm, and connect people to support such as housing, employment, health care, and counseling. Programs also need local knowledge, reliable partners, supervision, and a way to learn from the work. The approach and job titles vary by program.

A credible messenger has lived experience and community ties that can make a relationship possible. Credibility is a strength, but it does not replace training, sound judgment, or organizational responsibility.

Street outreach worker

Builds relationships with people and neighborhoods affected by violence, stays in contact, and helps connect people to support they can use.

Violence interrupter

Works within a trained team to recognize escalating conflict and help prevent retaliation. This is a defined role in some outreach models, not a solo assignment to enter dangerous situations.

Hospital-based intervention specialist

Meets people after a violent injury when a hospital program offers the service. With the person's agreement, helps carry support from the bedside into life after discharge.

Case manager or navigator

Works with a participant on goals, service access, and follow-through. The role may sit within an outreach or hospital-based team.

These are examples of roles, not a single national job description. A program may combine duties or use different titles. Read the CVI field guide for the approaches and terms behind them.

Considering the career

A practical route into the work.

Find the work where you live.

Look for local community-based outreach teams, hospital-based violence intervention programs, and youth-serving organizations. Read their actual job descriptions: the population, hours, setting, travel, documentation, and on-call expectations can differ. Ask to learn about the program through a public event or informational conversation before applying; do not seek access to participants or sensitive cases.

Bring strengths; expect training.

Listening, local relationships, consistency, boundaries, teamwork, and the ability to navigate services all count. Ask an employer how new staff learn de-escalation, confidentiality, trauma-informed practice, local referral options, safety procedures, documentation, and when to call a supervisor or a qualified specialist. Requirements differ by role and employer.

Interview the organization, too.

Ask who supervises field decisions, how workers get backup after hours, which partners actually accept referrals, how the team responds after a traumatic event, and whether pay and scheduling match the work. A worker should not have to carry every crisis or compensate for missing services alone.

Understand credentials.

There is no single credential described here as a prerequisite for every CVI job. The HAVI offers a specific Violence Prevention Professional certification for frontline staff already working in an active hospital-based program for at least six months. Check the current HAVI requirements and the employer's listing before paying for training.

Use what comes next

The chapter guides below expand the five Action Pathways. Choose a practice area, then bring one question or situation to supervision. Your team should make clear which decisions belong to you and which require backup.

Read the chapter guides

Action pathway 01

Supporting Behavior Change

Chapters II–IV

Meet a person where they are, understand what is getting in the way, and support a next step they choose.

Chapter II

Trauma-Informed Practices

Repeated violence and loss can change how safe a conversation feels and how much trust someone places in a new worker. Behavior that looks like resistance may be a response to past harm or an immediate need. You cannot infer a diagnosis from it.

Put it into practice

  • Offer choices about where, when, and how to talk. Explain your role and what happens next.
  • Keep promises small enough to keep, and make access steps such as calls and forms manageable.
  • Notice progress without demanding that the person disclose trauma to earn support.

What this can look like: Instead of insisting on an office meeting, ask whether the person would rather talk briefly in a place they choose or schedule another time. Then follow through on the choice.

Chapter III

Empowering Positive Behavior Change

A goal becomes usable when it fits the person's readiness and immediate conditions. A job referral may go nowhere if housing, transportation, or safety is unstable. Assessment is an ongoing conversation, not a one-time form.

Put it into practice

  • Ask about five areas: readiness, urgent needs, risk and protection, trusted relationships, and the future the person wants.
  • Agree on one participant-led step and identify the support needed to complete it.
  • Revisit what changed at the next contact and adjust the plan instead of calling a missed step failure.

Using Assessments to Prioritize Resources & Support

Use what the person tells you, what the team observes, and what changed since the last contact to decide where help is most urgent. The assessment should direct support, not merely fill a file.

Key Assessment Areas

Readiness, immediate needs, conditions that increase danger or help keep someone safe (risk and protective factors), trust, and future goals each tell you something different. Do not reduce a person to one risk label.

What this can look like: If a participant wants work but has nowhere stable to sleep, work together on housing and transportation first. Keep the employment goal visible and return to it as conditions change.

Chapter IV

Motivational Interviewing (MI)

People are more likely to work toward a change they have named for themselves. Use open questions and reflective listening to understand what matters to them, including reasons they may not trust a program.

Put it into practice

  • Ask what the person wants to be different and reflect back what you heard before offering options.
  • Explore the gap between their own goal and current circumstances without arguing or pushing a plan.
  • Match support to readiness: build a relationship, weigh options, plan, act, and keep supporting progress as needed.

The Stages of Change Model

Readiness can shift across conversations and across different goals. Return to what this person is prepared to consider now, rather than treating a stage label as their identity.

What this can look like: If someone rejects job training because school went badly, ask what made that experience difficult and what kind of work would matter to them. Do not defend the program before understanding the concern.

Keep in mind: The stages of change can guide a conversation. They are not a diagnosis or a fixed route everyone follows.

Back to Action Pathways

Action pathway 02

Case Management that Actually Works

Chapter V · Chapter III assessment link

Turn a relationship and an assessment into a plan that reaches real services and survives the first barrier.

Chapter V

Effective Case Management & Systems Navigation

A plan should follow the participant's priorities. It connects a goal to specific steps, a person responsible for each connection, and a way to find out whether the support actually arrived.

Put it into practice

  • Start with urgent needs and the goal the participant names, then break the goal into steps they can use.
  • Check eligibility, wait times, cost, transportation, and consent before calling a referral available.
  • Follow up after a missed connection, learn what blocked it, and change the plan with the participant.

Case Study

Use the housing-and-work example to trace the whole chain: a goal, the barrier, a named partner, the participant's agreement, and a check on what happened. A referral is an attempt; access is the result to verify.

Making Effective Referrals

A warm referral means checking the service fit, connecting to a real contact with permission, handling practical obstacles, and following up. Maintain a current list of partners and bring repeated access failures back to the team.

What this can look like: Illustrative situation: Someone starts work but an unstable place to stay threatens the schedule. The worker and participant identify housing and transportation options, confirm a provider can help, and check whether the connection happened. The employment goal stays in view.

Keep in mind: For questions about which need to address first, return to the five assessment areas in Chapter III. Clinical and legal decisions belong with qualified partners.

Back to Action Pathways

Action pathway 03

Interrupting Violence in Real Time

Chapters VI–VIII · Bonus I

Prepare for high-risk moments, understand how conflict spreads, and work within a trained team's safety procedures.

Chapter VI

Crisis Management & Intervention Planning

A useful plan is made before a crisis. With the participant, identify situations that may escalate, a safe way to leave, trusted people they will contact, and support that can help after the immediate danger passes.

Put it into practice

  • Ask what tends to raise risk, including grief, money pressure, particular places, or particular people.
  • Name an exit option, a trusted contact, and the team's agreed response for urgent needs.
  • Check back after the moment and revise the plan based on what was actually usable.

Keep in mind: This is participant-owned preparation, not permission for a worker to improvise an emergency response. Use the program's trained escalation and emergency procedures when danger is immediate.

Chapter VII

Digital Conflict & Social Media Retaliation

A post can put an audience around a conflict and increase pressure to respond. The worker's job is to understand context without spreading the material or promising secrecy that the program cannot keep.

Put it into practice

  • If a participant raises a concerning post, listen privately and ask what is happening offline and how immediate the threat feels.
  • Use the team's privacy, safeguarding, and escalation rules; involve trusted support with consent when possible.
  • Avoid forwarding, reposting, or publicly challenging the content in ways that enlarge its audience.

What this can look like: A participant shows a screenshot of escalating threats. A trained worker checks context and immediacy with them, consults the team's response process, and helps identify a safer next contact without circulating the image.

Chapter VIII

Retaliation Prevention

After a shooting, grief, rumor, and pressure from others can pull people toward further harm. The people closest to the loss may need support early and again after the first wave of attention fades.

Put it into practice

  • Work through trusted relationships to learn who needs support and what pressure they are facing.
  • Offer a safe immediate step, connect grief or practical support, and coordinate with the team rather than acting alone.
  • Keep checking in after services and public attention move on, including after memorial events.

Keep in mind: Risk does not follow a universal hour-by-hour schedule. Follow the local team's safety plan and do not approach an unsafe setting alone.

Bonus I

Crisis Management & De-escalation

In a tense conversation, a worker can lower pressure by slowing their pace, acknowledging emotion, giving space, and offering a way to step back without humiliation. Training and backup determine when and how to engage.

Put it into practice

  • Use a calm tone and questions instead of demands when a conversation is safe to have.
  • Offer a concrete exit or pause and bring in a trusted supporter through the team's process.
  • After the moment, connect grief and longer-term support; consider mediation only when trained staff judge it appropriate.

Keep in mind: This overview is not a crisis or mental-health protocol. For imminent danger, use trained emergency procedures and qualified responders.

Action pathway 04

Taking Care of You: Self-Care for CVI Workers

Chapters I and IX · Bonus II

Understand what the work brings up for you and what support your organization owes the people doing it.

Chapter I

Healing Yourself First

Lived experience may help build trust, but it can also bring a worker's own grief or trauma into the room. Recognizing that pull helps you keep the participant's needs separate from your own story.

Put it into practice

  • Notice when urgency becomes a feeling that you alone must save someone.
  • Review the moment with a trusted supervisor or peer and name what is yours to do and what needs a team or specialist.
  • Set boundaries that let you remain present without making promises you cannot carry.

What this can look like: After a difficult contact, a worker feels personally responsible for every missed appointment. Supervision helps separate the worker's commitment from barriers the organization and partners must address.

Chapter IX

Prioritizing Wellness

Wellness is part of program quality. Exposure to grief and violence affects judgment and retention. A team needs a routine for checking in, sharing the load, and getting support after difficult events.

Put it into practice

  • Make space for a post-incident check-in and useful supervision, not only a count of completed tasks.
  • Set predictable coverage, breaks, and after-hours expectations so support does not depend on one worker always being available.
  • Ask leadership how confidential support and time away are accessed when strain accumulates.

Keep in mind: An organization cannot assign all responsibility for worker wellness to individual resilience. Staffing, pay, backup, and access to support are leadership decisions.

Bonus II

Self-Care & Burnout Prevention

Persistent exhaustion, numbness, impatience, or withdrawal are reasons to check what support is missing. They are signals for a conversation, not a score or a diagnosis.

Put it into practice

  • Notice a change in how you feel, work, and connect with others; take a brief reset when possible.
  • Tell a supervisor what needs to change in workload, coverage, or support and agree on a follow-up date.
  • Use trusted personal and professional supports without replacing professional care when it is needed.
Back to Action Pathways

Action pathway 05

Building a Strong Network & Using Data With Purpose

Across Chapters III and V

Use what workers learn to make referrals dependable and change barriers the team cannot solve one person at a time.

From Chapter III

Use Assessment to Learn, Not Just Report

A series of conversations can show whether needs, readiness, and protection are changing. Notes have value when they help a team choose support and see barriers—not just satisfy a reporting requirement.

Put it into practice

  • Record the goal, agreed step, connection attempt, barrier, and follow-up within your program's privacy rules.
  • Review patterns across contacts: which needs recur, which steps become possible, and where support stalls.
  • Bring the pattern to supervision or a team review so someone can change the resource plan.

What this can look like: If housing instability repeatedly prevents participants from using job referrals, the team can strengthen its housing partnership instead of treating each missed appointment as a separate motivation problem.

From Chapter V

Build a Provider Network That Follows Through

A list of service names is not a network. Workers need real contacts, current eligibility and wait-time information, and a way to learn whether a participant reached the support offered.

Put it into practice

  • Keep provider contacts, eligibility, costs, wait times, and transportation requirements current.
  • With the participant's agreement, connect to a named person and check whether the service happened.
  • Take repeated ID, intake, or access barriers to the partner and program leaders so they can change the handoff.

Keep in mind: The toolkit treats this as work across assessment and case management, not as a separate data curriculum. Protect participant information and follow local consent and documentation rules.

Risk Factors That Can Contribute to Youth and Gun Violence

Risk and protective factors sit at several levels. A risk factor points to a condition to address; it does not predict a person’s future.

Try it: Name one condition your team can change and one strength it can build on.

Read the edited field notes
  • Look beyond individual behavior to family, community, and institutional conditions.
  • Do not use a risk factor as a label for a young person.
  • Pair every concern with a practical support or protective factor.

The Best Tool in Violence Intervention

Marcus asks workers to examine their empathy before they enter hard situations. That judgment must be backed by training and support.

Try it: In supervision, examine a moment when frustration or judgment changed how you listened.

Read the edited field notes
  • Marcus presents empathy as a practice of seeing people without reducing them to one act.
  • Knowing the field and the local setting matters alongside lived experience.
  • His call for training and resources points to an organizational duty, not just an individual trait.

How To FAIL in Violence Intervention!

Coming in to fix someone can shut down trust. Start with what the participant wants and what support they will accept.

Try it: Replace one ready-made solution with a question about the participant’s goal.

Read the edited field notes
  • A worker’s turning point cannot be imposed on someone else’s timeline.
  • Ask what has worked for the person before offering advice.
  • A small step chosen by the participant is more useful than a plan they do not own.

The Process Every CVI Worker Needs to Understand

Leaving a pattern of violence is a process that needs steady relationships and usable pathways to housing, work, health care, and support.

Try it: Identify the support that must still be there after the first decision to change.

Read the edited field notes
  • Desistance is a process, not a single decision or deadline.
  • Connect progress to material supports and continued relationships.
  • Name which partner owns a gap that one outreach worker cannot fill.

The Role of Family In Violence Intervention

Family can be a source of support, strain, or both. Engage relatives when the participant wants it and when doing so is safe.

Try it: Ask which trusted people the participant wants involved, and what those people need to support the plan.

Read the edited field notes
  • Do not assume every family member is ready or safe to involve.
  • Listen to the family’s own needs and limits when involvement is welcome.
  • Connect household barriers to a network of support rather than placing everything on the participant.

Ask ICM

On a team

Make the next move useful.

Keep learning from participants, experienced coworkers, and the barriers you encounter. These habits help you practice with care while your team backs the work.

  1. 01

    Ask, practice, keep learning

    Ask what the person wants, what has helped before, and what feels possible now. Listen without assuming your path fits theirs. Have an experienced coworker or partner explain a process you do not know; practice new skills and let feedback change your approach.

  2. 02

    Take care of yourself

    Notice when grief, urgency, or the wish to rescue pulls you past your role. Set boundaries on availability, take a pause after difficult contact, and ask for backup or confidential support. Your employer must make coverage and support real.

  3. 03

    Learn from what happens

    Within your program’s privacy rules, note the participant’s goal, what support was offered, whether access happened, and where a handoff stalled. Revisit the plan with the person and bring repeated gaps to a team review so someone can change the system.

Your first months on a team

Build skill with a team before carrying the work alone.

Use the first months to observe, rehearse, and practice alongside experienced coworkers. Ask your program to show how its approach, safety rules, service network, and feedback work in real situations.

Know your role
Shadow a contact. Learn who the program serves, how people enter it, what you may promise, and when a decision belongs to a trained colleague or specialist.
Practice listening
Rehearse open questions, reflective listening, and offering choices about when and how to talk. Ask what matters to the participant before proposing a solution; invite feedback on what you missed.
See the whole person
With an experienced worker, consider readiness, urgent needs, risks and strengths, trusted relationships, and the future the person wants. Revisit these areas as circumstances change instead of treating an intake form as a verdict.
Test a handoff
Trace one referral from the person’s agreement to a named contact. Check eligibility, wait time, cost, transport, and whether support arrived. If it stalls, learn why and revise the plan together.
Know your backup
Practice the team’s rules for safe contact, immediate danger, and after-hours coverage before you need them. Know whom to call, what to document, and when to stop and get help.

Your program should provide coached practice, clear boundaries, and reliable backup. Confidence grows through supported decisions, not by improvising a crisis response or carrying an unavailable service alone.

Growing in the career

There is more than one next role.

Experience in direct service can open different paths. Talk with your organization about the training, responsibilities, and support each path requires.

Specialize
Deepen practice in outreach, hospital-based intervention, youth work, or service navigation. Research and evaluation, community organizing, policy, and legislation are also pathways; seek the methods, partnerships, and training each requires.
Supervise
Learn how to coach decisions, set boundaries, give field backup, and respond to worker exposure without asking staff to carry system failures.
Build
Strengthen referral partnerships, documentation, and quality review. Program management adds responsibility for staffing, resources, delivery, and accountability.

Ask whether advancement keeps experienced practitioners connected to the field and pays them for the added responsibility.
