Public health is dedicated to promoting and improving the health of people and their communities. Public health specialists work to research diseases, respond to epidemics, develop health programs, increase access to health services, and educate populations on proper health care. Public health may involve protecting individuals, communities, organizations, and entire populations. There are certain, core functions that are fundamental to achieving the goals of public health. These are referred to as the essential public health functions (EPHF), and dictate the work of public health professionals everywhere. The core functions of public health include:

Assessment

Policy Development

Assurance

Together, these functions work together to restore, improve, promote, and protect the health of the greater good, through collective action. The goals of public health, according to experts, are to: Below, we delve into the three core functions of public health and what they mean – for the public and specifically for future public health professionals.

The Three Functions of Public Health, Explained

1) Assessment

Assessment involves the collection and analysis of information regarding health problems. This means that public health professionals work to research health conditions, potential risks, and resources for communities related to health care and prevention. Assessment enables public health professionals to identify trends in disease, injury, and death, as well as the factors that cause these events. As cited by the Centers for Disease Control and Prevention (CDC), the essential services of this function are to:

Monitor environmental and health status, to further identify and resolve health problems

Identify and investigate environmental health problems and health hazards in communities

2) Policy Development

With the information gathered by those assessing public health, policy development can begin. Policy development involves the process of information sharing, consulting, and citizen participation to decide on public health measures. Stakeholders in public health weigh the available information regarding health problems, programs, and threats – and further decide which interventions or policy decisions are appropriate to serve the public interest. As explained by the CDC, the essential functions of public health policy developers are to:

Inform, educate, and further empower people about environmental health issues

Mobilize community partnerships and actions to identify and solve health problems

Develop policies that support individual and community environmental health efforts

3) Assurance

The third core function of public health is assurance, which involves active pushes to ensure communities are healthy and protected. Those in public health assurance work to make health services available to people and their communities. They also make sure these health services are of high quality and easily accessible for community members. Additionally, assurance involves the promotion and protection of public health through dedicated programs, events, campaigns, and other strategies to safeguard health and wellness across populations. The CDC clarifies that these services are meant to:

Enforce policies that protect environmental health and ensure safety
