Trends, forces, and the commonest mistake
Read the definition of a trend one clause at a time
- The standard's full definition: "a series of related events that has a range of causes and that illustrates significant social, political, cultural, environmental or economic changes and continuities over a period of time. Case studies should show a broad trend over time."
- "A series of related events" — plural, and connected. One event cannot be a trend, however important.
- "A range of causes" — a trend with a single cause is a consequence, not a trend.
- "Changes AND continuities" — both are named. A trend is not simply "things got better." It is what changed while other things stayed the same.
- "Over a period of time" — long enough that the change is visible as a direction, not as a jump.
- "A broad trend over time" — the standard's own instruction on scale.
Read the definition of a force the same way
- The standard's full definition: "an idea, concept, or condition which promotes social, political, cultural, environmental, or economic change or a combination of these."
- Three permitted kinds, and nothing else.
- An idea — a belief that spread and changed how people acted. Nationalism, evangelical religion, laissez-faire economics, ideas about racial hierarchy.
- A concept — an organising framework people used. Rights, citizenship, respectability, progress.
- A condition — a state of the world that pushed events one way. Industrialisation, land shortage, war, technological change, economic depression.
- What is NOT a force, and each of these is a common submission:
- A person. A leader may embody a force, but the force is the idea they carried.
- An event. A war is not a force; the conditions war created can be.
- An organisation. A political party is not a force; the ideology it promoted is.
- A piece of legislation. A law is an effect of forces, or an instrument of them.
- The test: can it be stated as a noun phrase without a proper name? Rising demand for land is a force. The New Zealand Company is not.
The commonest fatal error, named in both reports
- The 2025 report: "Trends centred on single events or individuals remained unsuitable for this standard."
- The 2024 report: "Some candidates are still choosing to write about events or individuals, making it difficult to achieve this standard."
- The word "remained" in 2025 matters — it means this was already the finding in 2024, and it did not improve.
- Why students do it. Every other History standard they have met — at Level 2 and at Level 3 — is built on an event. AS91439 is the only one that is not, and habit supplies an event when the box asks for a trend.
- The tell is the box on page 2. It is labelled Historical trend:, not Historical event:. If what you write there has a date, you have probably written an event.
The standard's own trend examples, and what they have in common
- The Explanatory Notes give four, each with the two questions to ask of it:
- Migration — British migration to New Zealand in the 19th century.
- Rebellion against autocracy — in Russia.
- Racism — anti-Chinese racism in New Zealand.
- The changing roles of women — in England, 1870 to 1930.
- Every one is a noun phrase describing a direction of change, not a thing that happened.
- Every one has a stated place and often a stated period. Migration alone is too broad to be a case study; British migration to New Zealand in the 19th century is a trend you can evidence.
- The 2024 report adds three that worked in practice: the changing role of women, changing attitudes to LGBTQ+ people, and New Zealand sovereignty.
- Notice the grammar of all of them: "changing X", "the rise of X", "the trend of X". If your box entry cannot be phrased that way, test it hard.
Worked Example
Worked example
A candidate is deciding what to write in the box on page 2. They have studied one body of material and have four candidate entries. Which is a trend, and why do the others fail?
- A: The passing of a landmark reform Act in a single year.
- B: The campaign leader who spent thirty years pressing for that reform.
- C: The reform organisation, founded 1885, disbanded 1920.
- D: Changing attitudes to [the issue] in New Zealand, 1880–1930.
Answer:
Step 1 — apply the first clause of the definition: "a series of related events."
A fails immediately. One Act is one event. It has a single date. This is an AS91438 subject, and a good one — but submitted to AS91439 it is the exact error both reports name.
Step 2 — apply the definition to the person and the organisation.
B fails. A career is a biography. It is a series of events, but they are related by belonging to one person rather than by illustrating a change in society. The 2025 report names trends centred on individuals as unsuitable.
C fails, and this one is subtler. An organisation's history looks like a trend — thirty-five years, many events, causes and effects. But the series is related by institutional membership, not by social change. Its "continuities" would be facts about the organisation, not about the society, and the standard asks for changes and continuities in social, political, cultural, environmental or economic life.
Step 3 — test D against every clause.
- A series of related events? Yes — the campaign, the debates, the legislative attempts, the shifts in press coverage, related by all bearing on the same attitude.
- A range of causes? Yes — several forces plausibly bear on it.
- Changes and continuities? This is where D earns its place. Attitudes changed on the issue while other attitudes — about who was entitled to speak publicly, or about the family — persisted. That contrast is the essay.
- Over a period of time? Fifty years, stated.
Step 4 — now name the forces D permits, and check each against the three kinds.
- The spread of ideas about individual rights — an idea. Valid.
- Urbanisation and the growth of paid work outside the home — a condition. Valid.
- The reform organisation founded in 1885 — not valid. It is an organisation. But the idea it promoted is, and rephrasing it that way converts an invalid force into a valid one at no cost.
Step 5 — note how A now becomes useful rather than wasted.
The Act in option A is evidence within the D essay — a datable point at which the trend became visible in law. The same material serves both externals: as the event in AS91438, and as evidence for the trend in AS91439.
