Short-term and long-term effects
The axis the question has forced outright
- 2023's question required ONE short-term and ONE long-term impact. Not suggested — required.
- So this axis is not optional preparation. A candidate whose two effects are both immediate has no answer to that version of the question.
- The other years left it open, which means a pair split on this axis works every year and a pair not split on it works in some.
- Prepare the split even if you hope for an open question. It costs nothing and it removes the one way this paper can catch you.
What counts as short-term and long-term
- There is no fixed number of years, and the standard gives none. Judge it against the event.
- Short-term effects are visible within roughly the first year or two, and are usually direct: people displaced, jobs lost, an organisation formed, a decision taken, a response mounted.
- Long-term effects unfold over years or decades, usually through institutions: a law still operating, a body still meeting, a pattern of employment that never returned, a settlement that shaped the next generation.
- Say which you mean, with a period attached. In the eighteen months following and over the following three decades do the work. Vague timing is the commonest way a split pair collapses back into one.
- The two are often the same process at two speeds — which is a problem. If your long-term effect is just your short-term effect continuing, they are one effect. They must differ in what changed, not only in how long it lasted.
Immediate and delayed are not the same as short and long
- An effect can be delayed and short — nothing for three years, then a sharp change lasting a year.
- An effect can be immediate and long — a change that began at once and never reversed.
- Naming both the onset and the duration is more precise than naming either, and precision is what the Merit descriptor rewards as detailed.
- A useful phrasing: beginning within months and still in place four decades later. Two facts, one clause.
Long-term effects and the evidence problem
- The longer the period, the more rival explanations there are. An effect claimed across thirty years is competing with everything else that happened in those thirty years.
- Three ways to defend a long-term claim:
- Institutional continuity. The body founded then is the body operating now, and it can be traced. This is the strongest form, because the institution is the evidence.
- A documented chain. Later decisions that cite the event or the arrangement it created.
- Counterfactual anchoring. The pattern before the event, and the pattern after, with the change dated. Show the before, not only the after.
- What does not work is asserting that something "changed New Zealand forever". It is unfalsifiable, and the reports describe exactly this kind of claim as description rather than analysis.
Continuity and change, which lives on this axis
- 2025's Excellence descriptor names continuity and change as a historical fundamental the strongest candidates used.
- Continuity is the natural partner of a long-term claim. Saying what persisted alongside the change makes the change measurable and stops the essay overclaiming.
- Three kinds of continuity are worth naming:
- What did not change at all — a structure, a distribution, a practice that carried on.
- What changed and then reverted — a wartime measure that lapsed, a spike that returned to trend.
- What took much longer to change than expected — the effect had a boundary, and naming the boundary is a judgement.
- One clause is enough. While X changed within two years, Y did not move for another generation.
Worked Example
Worked example
The question is: How did ONE short-term and ONE long-term impact of a significant historical event affect New Zealand society?
A student has these two effects prepared. Are they a valid split, and how would you strengthen them?
- Effect A: Employment in an industry fell sharply in the eighteen months after the event.
- Effect B: Employment in that industry never returned to its former level.
Answer:
Step 1 — test whether these are two effects or one.
They are one. B is A continuing. The thing that changed is identical — employment in one industry — and the only difference is the length of the observation. A marker reading both paragraphs finds one change described twice, and discussed only one effect is on the Not Achieved list.
Step 2 — keep the stronger one and replace the other. Keep A: it is short-term, economic, quantifiable and directly linked to the event.
Step 3 — find a long-term effect that differs in what changed, not only in duration. Ask what the fall in employment set in motion that was not itself falling employment:
- Did people move? A change in the region's population is a different thing from a change in the industry's jobs.
- Did an institution appear? A retraining scheme, a relief body, a new department.
- Did ownership change? Firms failing and being bought is a structural change, not the same as an employment level.
- Did the industry's role in the economy change permanently — replaced in exports by something else?
Step 4 — pick and date it. Suppose the answer is that the region's population declined steadily for two decades and did not recover. That is a different variable, a different group affected, a different domain arguably, and it can be dated with census figures.
Step 5 — defend the long-term claim. Use two of the three defences:
- Show the "before" — the region's population trend in the two decades before the event, which was flat or rising.
- Anchor to an institution or a document — a later inquiry, a regional development scheme, or an official report that cites the decline and its origin.
Step 6 — add the continuity clause. While the region's population fell for twenty years, the pattern of land ownership around it was unchanged until the 1970s. The effect had a boundary, and naming it is a judgement rather than a claim.
