🎯 How to Write a 16-Mark Cross-Period Essay
The 16-mark question (plus 4 SPaG marks) is the highest-value question on Paper 2 Section A. It always asks you to judge how far something changed across the full period c.1250 to the present. You must cover at least two periods and make a clear judgement. This is worth 20 marks in total — roughly a quarter of your Paper 2 score.
The Four-Paragraph Essay Structure
Worked Essay Plan: "How far did the role of government change in approaches to preventing disease, c.1250–present?"
This question appeared in the June 2023 AQA sitting. Use this plan as a model — adapt it for any government/public health question.
| Paragraph | Main Argument | Key Evidence to Use |
|---|---|---|
| Introduction | Government role changed enormously — from almost no involvement in the medieval period to taking full responsibility through the NHS by 1948. The most important turning point was the 1875 Public Health Act, which established the PRINCIPLE that government was responsible for public health. | Name the 1875 Act and the NHS (1948) immediately to signal your evidence base. |
| Medieval (c.1250–1500) | Government did almost nothing systematic to prevent disease. The prevailing belief was that disease came from God (as punishment) or from miasma — neither explanation demanded government action. The only notable interventions were reactive responses to plague. | Edward III ordered London streets cleaned during the Black Death (1348). Towns occasionally appointed plague inspectors. But these were emergency measures, not permanent public health systems. Most prevention was left to the Church or individuals. |
| Industrial (c.1800–1900) | Government began — reluctantly at first — to accept responsibility. Edwin Chadwick's 1842 Report on the Sanitary Condition showed that poverty and squalor caused disease. John Snow's 1854 cholera investigation proved contaminated water spread disease. Pasteur's germ theory (1861) gave a scientific basis for action. Parliament was forced to respond. | 1848 Public Health Act: voluntary — councils COULD improve water and sewers, but were not forced to. 1875 Public Health Act (Disraeli): compulsory — councils MUST provide clean water, sewers, and adequate housing. Death rates fell significantly in towns that implemented the Act. This Act is the turning point: it made public health a government duty, not a choice. |
| Modern (1900–present) | Government took full responsibility. The NHS (1948) went far beyond preventing disease — it provided free treatment for all, funded by taxation. Vaccination programmes (smallpox eradicated globally 1980), anti-smoking campaigns, and COVID-19 lockdowns all show the modern state treating public health as a core responsibility. | NHS (1948): treats over 1 million patients every 36 hours. Smallpox vaccination programme: disease eradicated worldwide by 1980 — impossible without coordinated government action. COVID-19 (2020): national lockdowns and mass vaccination of over 50 million people in the UK — the most intensive government public health intervention in history. |
| Conclusion | Overall, there was ENORMOUS change. The most significant turning point was the 1875 Public Health Act — not because it was the most dramatic intervention, but because it established the PRINCIPLE that government was responsible for public health. Without that principle, the NHS could never have been created. The medieval period showed almost zero government involvement; the modern period shows government as the primary provider of public health. This is a transformation, not just a change. | Counter-argument: some continuity exists — governments still rely on individuals (scientists, doctors) and technology (vaccines, clean water engineering) to actually deliver public health. The government provides the framework; others provide the solution. |
What Each Level Looks Like for This Question
| Level | Marks | What the Answer Does | Example Student Response |
|---|---|---|---|
| Level 1 | 1–4 | Lists facts from one or two periods with no explanation. No argument, no judgement, no connections between periods. | "In medieval times they used prayer to stop disease. Now we have the NHS and vaccines. So things have changed a lot." |
| Level 2 | 5–8 | Describes changes with some evidence. Covers more than one period. But explanations are basic — no analysis of WHY things changed or how significant the change was. | "The government started getting involved after Chadwick's report in 1842. He showed that dirt and poverty caused disease. The 1848 Public Health Act was passed but it was voluntary. Later the 1875 Act made councils improve sanitation. The NHS was set up in 1948." |
| Level 3 | 9–12 | Explains change AND continuity with specific evidence from multiple periods. Shows HOW things changed — cause and consequence. May identify a turning point but without full analysis of why that turning point matters more than others. | "Government involvement in preventing disease grew significantly in the 19th century. Before Chadwick's 1842 Report, central government took almost no action — disease was seen as God's punishment or caused by miasma. Chadwick's statistical evidence that poverty and dirt were linked to disease death rates shifted thinking. The 1875 Public Health Act (Disraeli) was compulsory — for the first time councils were legally required to provide clean water and sewers. This led directly to falling death rates in industrial towns, showing that government action was effective. By 1948, this principle had expanded to the NHS — free healthcare for all, funded by taxation, treating 1 million patients every 36 hours." |
| Level 4 | 13–16 | Analyses change AND continuity across the FULL period (c.1250–present). Makes a clear JUDGEMENT about the extent and nature of change. Identifies the most important turning point with reasoning. Acknowledges counter-arguments. Shows how periods connect. | "The role of government changed enormously across this period — but this change was not gradual or smooth; it accelerated dramatically at two key moments. In the medieval period, government played almost no role in preventing disease: without an understanding of disease causes (miasma and God's punishment were the dominant theories), there was no intellectual basis for systematic government action. The 1875 Public Health Act represents the most important turning point — not because it was the most dramatic intervention, but because it established a new PRINCIPLE: that government was legally responsible for public health. This principle, once established, could not be reversed. The NHS (1948) was its logical consequence. This represents not just greater government involvement but a transformation in what government is FOR — making the change across this period qualitative as well as quantitative." |

Factor Analysis Across All Four Periods — Synthesis Table
For the highest marks, you need to show how the same factors operated differently across all periods. Use this table to plan cross-period essays on ANY of the five key factors:
| Factor | Medieval (c.1250–1500) | Renaissance (c.1500–1700) | Industrial (c.1750–1900) | Modern (c.1900–present) |
|---|---|---|---|---|
| Individuals | Hippocrates, Galen (ancient authorities still dominant). No new individual thinkers challenging the system. | Vesalius (anatomy, 1543), Harvey (blood circulation, 1628). Individuals begin challenging Galen using observation. | Jenner (vaccination, 1796), Pasteur (germ theory, 1861), Koch (specific bacteria, 1870s–80s), Snow (cholera, 1854). | Fleming (penicillin, 1928), Florey and Chain (mass production, 1940s), Watson and Crick (DNA, 1953), Barnard (heart transplant, 1967). |
| Government | Almost no involvement. Reactive measures only (Edward III cleaning streets during Black Death, 1348). | Henry VIII dissolved monasteries (1530s) — removed Church hospitals. Government did not replace them. | 1848 Public Health Act (voluntary). 1875 Public Health Act (compulsory) — turning point. Local government must provide clean water and sewers. | NHS (1948) — free healthcare for all. National vaccination programmes. Public health campaigns (anti-smoking). COVID-19 lockdowns and mass vaccination (2020–21). |
| Technology | Very limited. Herbal remedies, basic surgery. No instruments to see inside the body. | Printing press (spreads medical knowledge across Europe). Early dissection instruments. Padua anatomy theatre. | Microscope (enables germ theory). Industrial-scale clean water infrastructure. Anaesthesia (1847) and antiseptics (1867) transform surgery. | X-rays (1895), CT/MRI scanners (1970s–80s), gene sequencing (1970s onwards), mRNA vaccine technology (2020s). Technology drives every major advance. |
| War | Crusades spread disease but also brought contact with Islamic medicine (Avicenna's Canon of Medicine). | Military surgeons (Paré) developed ligatures and egg-yolk wound treatments — rejecting cauterisation. | Crimean War (1853–56): Nightingale's statistical work on sanitation in hospitals directly influenced public health thinking. | WW1: blood transfusion developed (1916–18). WW2: penicillin mass-produced (1944) — saved the lives of soldiers who would otherwise have died from infected wounds. |
| Chance | Limited evidence. Most medicine followed traditional authorities closely. | Paré ran out of boiling oil (chance) — discovered that egg-yolk treatment worked better than cauterisation. | No major chance discoveries in this period — germ theory and public health were systematic, evidence-based processes. | Fleming left a petri dish uncovered (1928) — mould killed surrounding bacteria, leading to penicillin. Classic example: prepared mind + chance observation = discovery. |
Quick Check: Plan a 16-mark essay for this question: "How far did the role of individuals change as a factor in medical progress, c.1250–present?" Write your introduction and conclusion only.
Model Introduction: "The role of individuals in driving medical progress remained significant throughout the period c.1250 to the present — but the nature of that role changed dramatically. In the medieval period, individuals were constrained by Church authority and the dominance of Galen; by the 20th century, individuals worked within large institutional and governmental frameworks that both enabled and sometimes overshadowed individual genius. The most important shift occurred in the 19th century, when individuals began working scientifically and systematically rather than relying on traditional authority."
Model Conclusion: "Overall, the role of individuals changed significantly in HOW they worked — from lone scholars relying on ancient authorities (medieval) to scientific researchers working with institutions, governments, and international teams (modern) — but remained consistently important throughout. The most significant turning point was Pasteur and Koch's work in the 1860s–1880s, because they established a scientific method for identifying specific disease causes that transformed individual discovery from scholarly opinion into verifiable fact. However, there is strong continuity: individuals in every period — Vesalius, Harvey, Jenner, Pasteur, Fleming, Watson and Crick — made the breakthroughs that advanced medicine. What changed was not the importance of individuals, but the tools, frameworks, and scale within which they worked."
