What this dot point is asking
WACE wants you to assess the reliability of health information and explain how health literacy protects consumers. A strong answer applies clear criteria to judge a source or product in the stimulus, identifies marketing influences, and links health literacy to better decisions. Marks reward applied evaluation, not a generic list of tips.
Criteria for evaluating health information
Reliable information can be judged against several criteria. Source asks who produced it and whether they have relevant expertise, such as a government health body or a peer-reviewed study. Purpose asks why it was produced, because information designed to sell a product is less trustworthy than information designed to inform. Evidence asks whether claims are supported by research rather than testimonials or opinion. Currency asks whether the information is up to date. Bias asks whether the producer has a commercial or other interest that could distort the message. Applying these criteria to a specific source is what the exam rewards.
Evaluating products and services
The same critical approach applies to products and services. For products such as supplements, devices or fad diets, consumers should check whether claims are backed by evidence, whether the product is approved or regulated, and whether the seller stands to profit from exaggerated benefits. For services such as clinics, practitioners or online programs, consumers should check qualifications, registration, accreditation and whether the service is appropriate to their needs. Cost, accessibility and the consumer's rights and avenues for complaint also matter.
How marketing and media influence consumers
Marketing and the media shape consumer decisions, often in ways that work against health. Techniques include emotional appeals, celebrity and influencer endorsement, selective use of statistics, and framing wants as needs. Globalised advertising of unhealthy products is especially powerful. Recognising these techniques is part of health literacy: a critical consumer can see when persuasion is replacing evidence and adjust their decision accordingly.
How health literacy supports decisions
Health literacy ties the topic together. A health-literate consumer can locate trustworthy sources, apply evaluation criteria, see through marketing, understand the information, and act on it safely. Because health literacy is unevenly distributed, improving it is also an equity issue: supporting people with lower literacy through plain-language information and trusted advice reduces a real barrier to good health.
How this maps to the exam
Expect a stimulus presenting a health claim, advertisement, product or service. You may be asked to evaluate its reliability, identify the marketing techniques used, or explain how health literacy would lead to a safer decision. Apply the evaluation criteria directly to the stimulus and name the specific features that make it trustworthy or not.
Exam-style practice questions
Practice questions written in the style of SCSA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
WACE 20226 marksAn advertisement claims a supplement 'detoxes your body and boosts immunity, as used by top athletes'. Evaluate the reliability of this claim and explain how health literacy would support a safer consumer decision.Show worked answer →
A 6 mark response needs criteria applied to the claim, then the health literacy link.
- Apply the criteria
- Source: an advertiser selling the product, so not independent. Purpose: to sell, not inform, which lowers trust. Evidence: a celebrity-athlete endorsement is a testimonial, not research; "detox" and "boosts immunity" are vague, unmeasurable claims. Bias: clear commercial interest.
- Reach a judgement
- The claim is unreliable: persuasion is replacing evidence, so a consumer should not act on it without independent, peer-reviewed support or regulatory approval.
- Health literacy link
- A health-literate consumer recognises the marketing techniques (endorsement, vague claims), seeks a trustworthy independent source (a government health body or pharmacist), and so avoids wasting money or risking harm.
Markers reward criteria applied to this specific claim, a justified judgement, and a clear health literacy connection.
WACE 20234 marksIdentify two criteria a consumer should use to evaluate the reliability of online health information, and explain why each matters.Show worked answer →
A 4 mark response needs two criteria, each explained.
Source and expertise. Who produced it and are they qualified (for example a government health body or peer-reviewed study)? It matters because an expert, independent source is more likely to be accurate than an anonymous or commercial one.
Purpose and bias. Why was it produced and does the producer profit? It matters because information designed to sell is more likely to exaggerate benefits and omit risks than information designed to inform.
Markers reward two genuine criteria with a clear reason each affects reliability.
