Quick Answer: A community health worker (CHW) is a frontline public health professional who serves as a trusted bridge between communities and the healthcare system, providing health education, care navigation, and social services support, often within the community they themselves come from.

If you’ve ever wondered, ‘What is a community health worker?’, ‘What does CHW stand for?’ and ‘What do they do?’, you’re in the right place. 

Community health workers (CHWs) work where the need is greatest: in under-resourced neighborhoods, rural clinics, homeless shelters, schools, and people’s homes. They speak the language, literally and culturally, of the communities they serve. And they do work that clinical providers often cannot, building relationships over time, navigating complex systems, and addressing the social determinants of health that drive most chronic disease.

This guide is for anyone considering becoming a CHW, or who is early in the role and wants to understand it fully, including the rewards, pathways, and the real emotional weight of the work.

What is a community health worker?

The World Health Organization defines community health workers as members of the communities where they work, selected by the community, answerable to the community, and supported by the health system. The emphasis on community membership is not incidental. It’s the source of a CHW’s power.

What unites every CHW, even if the term is used loosely in place of many different titles, is their position at the intersection of health and community. They are not doctors or nurses, but they can work alongside clinical teams to ensure that patients, especially those who are marginalized, uninsured, or distrustful of healthcare systems, actually receive and act on care. They also work in community-based settings, connecting community members to resources and programs, such as the Supplemental Nutrition Assistance Program (SNAP) benefit or transportation services, that enable health.

The CHW model has roots in the 1960s and 1970s, emerging from civil rights-era health movements and rural health programs that recognized the value of relationships with trusted community members in helping people access the health and social services they need to thrive.

Today, CHWs are recognized by the Bureau of Labor Statistics as an official occupation (SOC code 21-1094), and all 50 states have some form of CHW program or policy framework.

Who employs community health workers?

CHWs work across a wide range of organizations. Common employers include:

• Nonprofits and social service organizations, such as housing, substance use recovery, domestic violence, and re-entry programs.
• Schools and community-based organizations, particularly in maternal/child health and chronic disease management.
• Federally Qualified Health Centers (FQHCs) or community health centers that serve low-income and uninsured populations.
• Hospital community benefit programs within health systems are required to demonstrate community investment.
• Medicaid managed care organizations are increasingly hiring CHWs as Medicaid reimbursement for CHW services expands.
• County and state health departments and other public health agencies that are running disease prevention and outreach programs.

The expansion of Medicaid reimbursement for CHW services, now active in nearly half of states, is one of the most significant drivers of CHW hiring and of recent national recognition of CHW services. When CHW can receive reimbursement for client or patient encounters, the business case for hiring or scaling becomes much stronger.

What Does a Community Health Worker Do?

The question of what a community health worker does doesn’t have a single answer. The role is broad. CHWs are generalists by design, filling gaps between formal medical services and real-world community needs.

Core Responsibilities

• Health education and outreach, which includes explaining conditions, medications, and preventive behaviors in plain, culturally appropriate language
• Care coordination and navigation, helping clients schedule appointments, follow up on referrals, and understand discharge instructions
• Social determinants of health screening, supporting clients by identifying and addressing food insecurity, housing instability, and transportation barriers
• Home visits, including meeting clients where they live to assess needs and deliver services
• Case management, such as maintaining records, coordinating with care teams, and tracking client progress
• Crisis intervention, including responding to mental health crises, domestic violence, and substance use emergencies
• Community mobilization by building trust, raising awareness, and connecting community members to resources

Specialized Focus Areas

Many CHWs specialize in a specific population or health domain, such as maternal and child health, chronic disease management (diabetes, hypertension, asthma), behavioral health and substance use, HIV/AIDS and sexual health, homelessness and housing, aging and disability, and re-entry support for individuals released from incarceration. Again, this is because they have lived experience and have walked a journey that they then guide clients through. 

What is it like being a CHW?

CHW career guides often describe this work in aspirational terms, describing the long-term outcomes for clients who have reached resolution in their journey. It is aspirational, but it is also hard. CHWs routinely encounter homelessness and extreme poverty, active substance use, child abuse as mandatory reporters, domestic violence, and mental health crises, and often without immediate backup. Client deaths to overdose, violence, or disease are a real part of the work.

“You become very attached to your clients. When you lose someone, it stays with you. This job changes you and you have to be intentional about how you carry it.” — CHW and recovery counselor, recovery center

Vicarious trauma occurs when repeated exposure to others’ suffering begins to change the way a helper sees the world. Compassion fatigue is closely related and describes the gradual erosion of empathy and capacity for care as a result of chronic stress exposure. Both are real occupational hazards for CHWs.

Protective factors include peer support groups, access to mental health services, clear role definition, intentional community with colleagues, and self-care. When evaluating employers, ask directly: What does your organization do to support CHW wellness? 

CHWs in many states are mandated reporters for child abuse and neglect, creating real ethical complexity when a client has shared information in trust. Good training programs prepare CHWs for this terrain, not just the technical skills, but the emotional dimensions of navigating difficult obligations.

How does someone become a community health worker?

The CHW role is a starting point for many community or public health careers, and a destination in itself for others.

There is no universal educational requirement. Entry-level positions often require only a high school diploma or GED, particularly for outreach roles. Many employers prefer or require an associate’s or bachelor’s degree in public health, social work, or human services, or other CHW education.

One of the most distinctive features of CHW hiring is the explicit value placed on lived experience. An applicant who has personally navigated homelessness, substance use recovery, or chronic illness, or who has navigated the immigration process, often brings irreplaceable credibility and cultural competency. Many programs actively recruit from within communities, including peer recovery specialist programs.

Do CHWs need to be certified?

While most states do not require community health workers to be certified, education in community health work verifies existing competency in health education, care coordination, cultural responsiveness, documentation, and ethics.

As of 2025, more than 20 states have CHW certification programs, either state-sponsored, private, or run through associations, including Texas, Massachusetts, Ohio, Oregon, and Minnesota. These programs typically include a certain number of documented work hours, a written competency exam, a background check, and continuing education for renewal.

For CHWs who enter the role through lived experience, it provides a meaningful pathway into professional healthcare or social services careers. Building documentation, supervision experience, and a record of measurable client outcomes creates a strong foundation for advancement.

Is being a CHW right for you?

The people who thrive as community health workers are genuinely curious about other people’s lives. They are comfortable with ambiguity and complexity. They can be present with suffering without needing to immediately fix it. They have patience with systems that move slowly and clients navigating recurring crises. They find meaning in small victories, such as a client who finally connected with a doctor, a family that secured housing, or a child who is safer than they were last month.

If you recognize yourself in that description, community health work may be one of the most meaningful careers you can choose. The pay is not lavish, but it is growing. The work is hard, but it is important.
