Community health workers are frontline public health professionals who come from the communities they serve. The American Public Health Association defines them as trusted members of their communities who have an unusually close understanding of the people around them. That shared background is the defining feature of the role: unlike doctors or nurses, community health workers bridge the gap between healthcare systems and the neighborhoods, cultural groups, or populations that often struggle to access care. As of May 2023, roughly 58,550 people held this role in the United States, earning a median salary of $48,200 per year.
What Makes Them Different From Other Health Workers
The core distinction is trust. Community health workers live in or have deep ties to the populations they support. Many speak the same languages, share cultural backgrounds, and understand the daily realities that shape health decisions, from transportation barriers to food access to immigration concerns. This isn’t a clinical role in the traditional sense. Community health workers don’t diagnose or prescribe. Instead, they work alongside clinical teams to make sure people actually get the care, information, and resources they need.
Their value lies in reaching people that the formal healthcare system often misses. They meet people in homes, churches, community centers, and shelters. They translate not just languages but also the confusing logic of insurance systems, referral processes, and treatment plans into something a person can actually act on.
What Community Health Workers Actually Do
The National Council on CHW Core Consensus has identified ten core roles, but in practice, the work clusters around a few major functions. Cultural mediation is central: community health workers help individuals understand how health and social service systems operate while also educating those systems about the cultural norms and perspectives of the communities they serve. They build health literacy and facilitate cross-cultural communication in both directions.
Care coordination and system navigation make up another large share of the work. This means making referrals, following up to ensure people actually attended appointments, arranging transportation, tracking outcomes, and helping people overcome the practical barriers that prevent them from getting care. When someone is discharged from a hospital with a complicated follow-up plan, a community health worker may be the person who makes sure it actually happens.
They also provide direct services: basic screenings like blood pressure and weight checks, first aid, diabetic foot checks, and connecting people with food or other essential resources. Beyond hands-on services, they conduct outreach to identify people who need help, deliver health education in culturally appropriate ways, provide coaching and emotional support, and help build the capacity of individuals and entire communities to advocate for themselves.
Training and Certification
There is no single national certification for community health workers, and requirements vary widely by state. Approximately half of U.S. states have or are actively developing certification programs. Currently, 12 states run their own certification programs, including Arizona, California, Connecticut, Texas, and Massachusetts. Another five states have privately run credentialing boards, and six states manage certification through community health worker associations.
Most certification programs offer multiple pathways. One is typically rooted in completing a core competencies-based training program. The other recognizes practical work experience, usually requiring between 1,000 hours (about six months) and 4,000 hours (about two years) of documented work as a community health worker. Some states accept training completion alone, but most require a combination of formal training and hands-on experience. This flexibility is intentional: it allows people with years of grassroots community experience to enter the profession without starting from scratch in a classroom.
Impact on Chronic Disease
The strongest evidence for community health worker effectiveness comes from chronic disease management. A study using electronic health records at two federally qualified health centers found statistically significant improvements in several key indicators after patients worked with community health workers. At one center, average blood sugar levels dropped measurably, BMI decreased, and total cholesterol fell by nearly 12 milligrams per deciliter. At the second center, blood sugar levels showed an even larger improvement, and triglyceride levels dropped by over 22 milligrams per deciliter.
These changes may sound modest in isolation, but for populations managing diabetes, high blood pressure, or heart disease risk, consistent small improvements across an entire patient group translate into fewer complications, fewer emergency visits, and better long-term health. The improvements held up across different analysis methods, reinforcing that the effect was real rather than a statistical fluke.
The Financial Case for CHWs
Community health workers don’t just improve health outcomes. They save money. A Health Affairs study of a Medicaid-focused program found that every dollar invested in community health worker services returned $2.47 to the Medicaid payer within a single fiscal year. The team of community health workers in that study saved Medicaid over $1.4 million against program costs of roughly $568,000. Sensitivity analyses placed the return somewhere between $1.84 and $3.09 per dollar, depending on assumptions.
The savings came largely from reduced hospitalizations. Patients who worked with community health workers had a 30 percent lower rate of hospital admissions compared to a control group, and total inpatient charges were 39 percent lower at the one-year mark. These reductions make financial sense: community health workers address the social factors, like unstable housing, lack of transportation, or inability to afford medications, that drive expensive emergency and inpatient care.
At least 21 states now provide Medicaid payment for certain community health worker services, either through their state plans or managed care arrangements. This reimbursement infrastructure is still growing, but the economic evidence is accelerating its expansion.
Why Shared Identity Matters
The workforce is notably diverse and multilingual. Many community health workers speak English as a second language, which is a strength rather than a limitation when serving immigrant communities or non-English-speaking populations. States like Wisconsin and New York have been recognized for promoting a shared professional identity among their diverse community health worker workforces and for involving workers directly in shaping training and research efforts.
This shared identity, whether it’s based on language, ethnicity, neighborhood, or lived experience with poverty or chronic illness, is what allows community health workers to do something that clinicians often cannot: have honest, trusted conversations about the real barriers people face. A community health worker who has navigated the same social service systems, lived in the same housing conditions, or managed the same health challenges brings a credibility that no amount of clinical training can replicate. That trust is the foundation everything else is built on.
