What are the three core public health functions?

• A. Surveillance, Intervention, and Evaluation
• B. Diagnosis, Treatment, and Prevention
• C. Assessment, Policy Development, and Assurance
• D. Monitoring, Enforcement, and Funding

Answer: (C)

Public health practice rests on three core functions: assessment, policy development, and assurance. Assessment involves gathering and analyzing information about the community’s health, monitoring health status, and investigating health problems to know what needs attention. Policy development uses the evidence from assessment to create and promote policies and programs that address those needs, guiding decisions and priorities at the population level. Assurance ensures that essential health services are available, that laws and regulations are enforced as needed, and that there is a competent public health workforce and organization to carry out the work. Other options mix clinical care or operational tasks that aren’t the defining trio for public health. Diagnosis and treatment focus on individuals rather than population-wide health, while components like surveillance or evaluation, though related, don’t by themselves define the three core functions. Monitoring, enforcement, and funding describe important mechanisms but don’t capture the integrated framework of assessment, policy development, and assurance.
