Principles of Epidemiology is the MPH's deep graduate dive into the discipline the undergraduate Introduction to Epidemiology course only previewed — full methodological rigor for discerning disease patterns.
What D625 covers
The course offers in-depth exploration of foundational principles and methodologies crucial for discerning and interpreting health and disease patterns in populations. Learners engage with core epidemiological concepts: measures of disease frequency, study designs, and principles of causation.
Emphasizing practical application, the course equips learners with analytical skills and theoretical foundations for conducting epidemiological research and contributing to evidence-based public health practice.
The D625 performance assessment
Expect a performance assessment requiring you to apply epidemiological study design and causation principles to analyze a specific disease pattern or research question.
Key topics in D625
- Measures of disease frequency
- Epidemiological study designs
- Principles of causation
- Evidence-based public health research
Writing tips for D625
Follow the task instructions and rubric line by line
WGU performance assessments for D625 are graded against a fixed rubric — every rubric line has to be visibly addressed, usually with a labeled heading that mirrors the rubric language. Skipping a rubric point because it seems minor is the single most common reason a competent submission comes back "Not Yet Competent" for revision.
Ground public health analysis in a specific population or community, not generalities
WGU evaluators are trained to distinguish genuine public health analysis from a paraphrased textbook summary. Anchor your submission in the specific population, community, or health issue the task provides, and show data-driven reasoning connecting your recommendation to that real context.
Because WGU is self-paced, don't let "no deadline pressure" become no submission
There's no weekly due date forcing progress, which means procrastination costs more at WGU than at a traditional term-based school — a stalled task can quietly eat weeks of a term. Treat your own target date for each D625 assessment as a real deadline.

Why students seek help with D625
Students sometimes conflate correlation with causation in their analysis — the course specifically covers principles of causation, and the rubric typically checks that this distinction is respected.
