PHE 500 is SNHU’s Principles of Public Health course. It centers on principles of public health: its history and achievements, the core functions of assessment, policy development and assurance, the ten essential public health services, the federal, state and local public health system, stakeholders and partnerships, social determinants and equity, public health law and ethics, the health impact pyramid and the public health workforce. Every module below opens a full sample paper or takes a free request for one; searches like "phe 500 module 3", "PHE500 sample paper" and "PHE 500 milestone example" land on this page.
What PHE 500 is really about
PHE 500 opens SNHU's MPH and asks students to see a health problem the way a health department does, as a set of services, partners and decisions rather than a single disease. Strong work defines the issue with surveillance data, places it in history, names who in the system is responsible for what, uses the ten essential services as a working checklist rather than a list to recite, weighs ethics and law and recommends interventions with the broadest reach the evidence supports.
The samples are set in a composite county of about 90,000 people in central Pennsylvania, where a busy summer brought dozens of rabid animals to the state laboratory, two bat exposures at a children's camp and a sharp rise in people starting post-exposure vaccine. The county health department, animal control officers, veterinarians, hospitals and a federal wildlife program all play a part. The county, agencies and people are illustrative.
What PHE 500’s modules ask for
Across ten modules, PHE 500 typically asks for discussions on the meaning of public health, the system, ethics and the workforce, short papers on the essential services and on determinants and equity, three milestones covering an issue's history and scope, its stakeholders and system response and an intervention analysis, and a final public health issue analysis.
Where students lose points in PHE 500
The most common PHE 500 deduction is listing the ten essential services without showing how a real agency delivers them for the chosen issue. The second is describing a disease clinically while ignoring surveillance, the system and the people who carry out the work. Graders also mark down analyses that treat every agency as one undifferentiated government, skip ethics and law, or recommend education alone when changes in context would reach more people. The fix is to follow the issue through the system, service by service.
The PHE 500 drawers
PHE 500 Module 1 Discussion example
A discussion in which a composite MPH student defines public health through one night at a central Pennsylvania summer camp, when a bat found in a cabin of sleeping children set off calls between the camp, the county health department, the state laboratory, a hospital and parents, showing that public health is collective, preventive and largely invisible, drawing on the Institute of Medicine, Pieracci and colleagues and Tarantola's history of rabies.

PHE 500 Module 2 Essential Services Short Paper example
A short paper in which a composite MPH student maps a central Pennsylvania county's rabies work onto the three core functions and the ten essential public health services, from testing 412 animals and tracing exposures to pet vaccine clinics, ordinances, vaccine access for uninsured residents and staff training, with a table showing the service, the county's activity and the gap, drawing on the Institute of Medicine, Castrucci and Pieracci and colleagues. Full sample paper, read it free.
PHE 500 Module 3 Milestone One example
A first milestone in which a composite MPH student introduces rabies as the issue for a public health analysis: how the virus spreads and why it is nearly always fatal once symptoms begin, four thousand years of fear, Pasteur's vaccine and the end of dog rabies in the United States, the shift to bats and raccoons, national death and vaccine figures, three years of county data from central Pennsylvania and the costs that make rabies an access problem, drawing on Tarantola, Pieracci and colleagues, Christian and colleagues and Slate and colleagues. Full sample paper, read it free.
PHE 500 Module 4 Discussion example
A discussion in which a composite MPH student follows one rabid raccoon in central Pennsylvania through the public health system, from a township animal control officer and the county health department to the state laboratory, federal vaccine guidance and a federal wildlife baiting program, showing how federal, state, local and private partners divide the work and where the seams between them cause delays, drawing on the Institute of Medicine, Slate and colleagues and Rao and colleagues. Full sample paper, read it free.
PHE 500 Module 5 Milestone Two example
A second milestone in which a composite MPH student maps the stakeholders in a central Pennsylvania county's rabies problem by interest, influence and role, from residents, camps and farmers to hospitals, veterinarians, wildlife rehabilitators and state and federal agencies, then describes the system's current response under assessment, policy development and assurance, where interests conflict and which partnerships are missing, drawing on the Institute of Medicine, Castrucci, Christian and colleagues and Slate and colleagues. Full sample paper, read it free.
PHE 500 Module 6 Determinants Short Paper example
A short paper in which a composite MPH student applies the social determinants of health to rabies in a central Pennsylvania county, separating what shapes exposure, such as farm work, old housing, camps and unvaccinated barn cats, from what shapes access to post-exposure vaccine, such as insurance, language, fear of authorities, distance and time off work, with a table of determinants and three equity-focused changes including pre-exposure vaccine for high-risk workers, drawing on Braveman and Gottlieb, Pieracci and colleagues and Rao and colleagues. Full sample paper, read it free.
PHE 500 Module 7 Discussion example
A discussion in which a composite MPH student weighs a central Pennsylvania county's order that an unvaccinated family dog exposed to a rabid raccoon be either euthanized or held in a strict months-long quarantine at the owner's cost, testing it against the five conditions Childress and colleagues proposed for overriding personal interests and concluding that the order is justified but its cost to a low-income family is not, drawing on Childress and colleagues and Pieracci and colleagues. Full sample paper, read it free.
PHE 500 Module 8 Milestone Three example
A third milestone in which a composite MPH student sorts rabies interventions for a central Pennsylvania county onto Frieden's health impact pyramid, from insurance and paid leave at the base through free pet vaccine clinics, bat-proofing and wildlife baiting, pre-exposure vaccine for high-risk workers and a fund for post-exposure care to education at the top, compares them on reach, evidence, cost, equity and feasibility in a table and recommends a package tied to the ten essential services, drawing on Frieden, Slate and colleagues, Rao and colleagues, Pieracci and colleagues and Castrucci. Full sample paper, read it free.
PHE 500 Module 9 Discussion example
A discussion in which a composite MPH student counts the people behind one summer of rabies calls in a central Pennsylvania county, two nurses, one animal control officer for four townships, a part-time epidemiologist and a state laboratory, and connects their strain to national findings on an aging, underpaid and stretched public health workforce, then proposes cross-training, a shared regional on-call rota and student pipelines, drawing on Sellers and colleagues and the Institute of Medicine. Full sample paper, read it free.
PHE 500 Module 10 Final Project example
A final public health issue analysis in which a composite MPH student brings together a term's work on rabies in a central Pennsylvania county: the disease and its history, national and county magnitude, stakeholders and the system's response by core function, the determinants that stack exposure and barriers on farm workers and other residents, the ethics of quarantine orders, interventions sorted on the health impact pyramid and a recommended package with essential services, measures and a phased start, drawing on ten sources from Tarantola to Rao and colleagues.

Using a PHE 500 sample the right way
Read a PHE 500 sample by checking whether the issue is sized with surveillance data, whether each essential service is shown at work, whether agencies and stakeholders are named with their roles, whether ethics and law are weighed and whether interventions are judged by reach. For PHE 500, bring the prompt, your chosen issue and the rubric; a first custom sample is returned free in 24-48h.

What is the PHE 500 final project?
A public health issue analysis built over three milestones: the issue's history and size, its stakeholders and system response, and an intervention analysis.
How should the ten essential services be used in PHE 500?
As a working checklist showing how agencies assess, plan, act and assure services for your chosen issue, not as a list to recite.
