The Certified in Public Health (CPH) is a professional credential administered by the National Board of Public Health Examiners (NBPHE), an organization created to credential the public health workforce. NBPHE describes the CPH as the only credential of its kind for public health professionals, demonstrating both knowledge of key public health sciences and a commitment to continuing education focused on emerging and established public health issues. It is aimed at people working across the public health field - practitioners in health departments, researchers, analysts, faculty and students - who want to distinguish themselves and signal competence to employers and communities. According to NBPHE, professionals, leaders, alumni and faculty from more than 95 countries have sat for the CPH credential, and active certificants have reported over 500,000 education hours while staying current in the field. Certification is not one-and-done: NBPHE frames the CPH as a life-long learning credential, with recertification activity required to maintain it. NBPHE publishes a content outline, candidate handbook, study resources, and information on fees, discounts, and accommodations to support preparation. Topics on this exam: Public Health Sciences and Public Health Practice and Policy. The CPH study guide has 2 sections and about 691 words.

01

Public Health Sciences: Core Concepts and Question Traps

Public health sciences integrate epidemiology, biostatistics, environmental health, and behavioral/social sciences. A CPH candidate must move fluidly between these lenses rather than treating them as isolated subjects. Know measures of frequency (incidence vs. prevalence), measures of association (risk ratio, rate ratio, odds ratio), and the distinction between association and causation.

Public Health Practice and Policy: Turning Science into Action

Public health practice and policy covers assessment, assurance, and policy development-the core functions-and the ten essential public health services that operationalize them. Candidates should understand how needs assessment, program planning, implementation, and evaluation form a continuous cycle. Assessment and planning. Know the difference between community health assessment and community health improvement planning.

  • Practice questionsWhich measure of disease frequency is defined as the number of new cases occurring in a population at risk during a specified time period divided by the person-time at risk?
  • FlashcardsIncidence rate. Number of new cases of a disease occurring in a population during a specified period divided by the person-time at risk; measures the speed of new disease occurrence.
  • Cheat sheetIncidence rate = new cases / person-time at risk; cumulative incidence = new cases / persons at risk at start.
  • Key termsEpidemiology. The study of how health-related states and events are distributed in populations and the factors that influence that distribution, used to control health problems.
  • Study planDefine the core epidemiologic measures (incidence, prevalence, attack rate, case fatality) and compute each from a worked dataset.
  • Common mistakesBoth are described as 'how common a disease is', so candidates pattern-match on the word 'common' instead of on whether the question involves new events (incidence) or existing cases at a point in time (prevalence).
