HS 326 study guide
HS 326 · Work through your exam, one topic at a time.
HS 326, Health Science Reasoning and Evidence-Based Practice, is a multiple-choice assessment of whether a candidate can move from a clinical or public-health question to a defensible answer: framing the question, judging study design, reading results critically, and deciding whether and how the evidence should change practice. It suits students and early-career practitioners in nursing, allied health, public health, medicine, and health administration, plus anyone whose role involves appraising literature, interpreting population data, or sitting on guideline, quality-improvement, or journal-club committees. The HS 326 study guide has 7 sections and about 3,126 words.
01Scientific Inquiry and Research Design
The Scientific Inquiry and Research Design domain asks you to translate a clinical or population problem into an answerable question and then choose a design that can actually answer it. HS 326 tests the whole chain: paradigm, question type, design, sampling, control of bias, and the limits each design places on inference.
452 words, about 2 min02Evidence Appraisal and Critical Reading of the Literature
The Evidence Appraisal domain tests whether you can judge a paper's trustworthiness rather than merely summarize it. Expect questions on evidence hierarchies, risk-of-bias instruments, synthesis methods, and the gap between statistical significance and clinical usefulness.
438 words, about 2 min03Biostatistics and Quantitative Reasoning
Biostatistics and Quantitative Reasoning tests whether you can choose the right test, read an estimate correctly, and avoid the classic misinterpretations. HS 326 emphasizes interpretation over computation: you will rarely derive a formula, but you will be asked what a p value, a confidence interval, or a likelihood ratio actually licenses you to say.
445 words, about 2 min04Epidemiology and Population Health
Epidemiology and Population Health tests your command of disease frequency, association, causation, and bias at the population level, plus the policy-facing tools: screening criteria, surveillance logic, and health equity measurement. Expect computations in a two-by-two table and conceptual questions about what a measure can and cannot support.
443 words, about 2 min05Clinical Decision-Making and Evidence-Based Practice
This domain tests whether you can carry evidence into an actual decision for a specific patient, team, or service. HS 326 wants the five-step process applied rather than recited: ask, acquire, appraise, apply, and audit the result.
463 words, about 2 min06Ethics, Integrity, and Regulatory Considerations
This domain covers the rules governing research and the use of evidence: ethical principles, consent, oversight bodies, regulatory frameworks, and research integrity. HS 326 tests applied judgement, so you must recognise which principle is at stake, which regulation applies, and what must happen before a study starts or a paper is published.
436 words, about 2 min07Communication and Interprofessional Application of Evidence
HS 326 tests communication as a skill with measurable elements: how risks are framed, how evidence is translated for patients and colleagues, and how teams share decisions. Questions ask you to choose the framing or format that preserves understanding, and to identify the team behaviours that make evidence stick.
