PHE500: Principles of Public Health

A study guide to SNHU's PHE500, the required graduate foundation course on public health history, the system, essential services and professional portfolio.

Updated October 2026 · 5 min read

PHE500 is the required, foundational graduate course in SNHU's public health program.

The catalog says it introduces the history of public health, the structure of the public health system, the ten essential services and the core knowledge areas, so students can understand the complex factors that affect health behaviors in the community.

It also introduces the range of public health professions and the development of a professional portfolio.

At graduate level, an introductory topic is expected to be handled with more critical depth. Summaries are not enough; you need to analyze, compare and cite scholarly work.

Key Concepts Explained

Three Core Functions

Public health practice is often summarized as assessment, policy development and assurance. The essential services spell these out in more detail. Mapping a program to the core functions shows you understand the framework.

Determinants of Health

Health outcomes are shaped by biology, behavior, environment, and social and economic conditions. Graduate answers go beyond individual choices to name structural factors.

Invented illustration: A weak response says a community has high diabetes because people eat badly. A stronger one considers food access, income, neighborhood design and healthcare access, and proposes action at more than one level.

Building a Portfolio

A professional portfolio gathers work samples with short reflections on what each shows. Start saving your best pieces and notes from the first module.

Typical Assignments and How to Approach Them

Starting a Professional Portfolio

The catalog says PHE500 introduces the development of a professional portfolio. Treat it as a record of growth, not an afterthought. The table shows one way to organize it from the first module.

SectionWhat to includeWhy it matters
Career focusRoles that interest you and whyGuides which skills to highlight
Work samplesYour strongest papers or plansShows what you can do
ReflectionsA paragraph on what each sample demonstratesConnects work to competencies
Skills inventoryResearch, communication, analysis, leadershipHelps you see gaps to fill

Keep copies of feedback from instructors too. Looking back at comments across a program is one of the fastest ways to see which skills you have built and which still need attention.

When a PHE500 task asks you to explore a profession, use real job descriptions and professional association information. Describe the responsibilities and the knowledge areas the role draws on, and connect them to the core areas listed in the catalog.

Moving from Description to Analysis

Graduate rubrics reward analysis. When a task asks you to discuss the history or structure of public health, add a layer beyond description.

Each of these moves turns a summary into a judgment, and graders look for judgment at this level.
