How long is a long comparison?

Move a comparison’s end dates and the story can change. The span on the label matters less than how many of the years inside it belong together.

Explainer · By Andre Kaljevic · Published · Last reviewed

Covers: Eton’s 2015 list of where its leavers went and its later 2025 counts show what is counted changing under the same heading. A separate 2015–2025 A-level comparison shows the period checks the site already runs.

The answer

A decade sounds like a long time, but a long span of years and a long run of comparable figures are different animals. Nothing deserves the name of a lasting pattern until someone has checked which years the schools share, where the gaps fall, whether a definition changed and which runs of years were tested, and two end points that count different things, such as destinations one year and acceptances another, can’t make a trend at all. When a school is said to have risen or fallen over ten years, the first thing to ask is what the end points count.

These figures belong to the years and groups discussed in this article. Changing your shortlist leaves this example as it is.

Destinations in 2015, acceptances in 2025

Eton’s two Oxford and Cambridge figures, in the cards above, look made for each other until you read the labels. The earlier one counts destinations, where the leavers of 2015 went; the later one counts acceptances in the 2025 cycle, following applications from the school, and its card says firmly that it is “not substituted for the earlier destination measure”. A line drawn between them would begin by measuring one thing and end by measuring another, like a party counted first from the photographs and then from the guest list. Each can be read on its own terms; joining them would take figures counting the same outcome for compatible groups. (Nor would a rise in overseas destinations, on its own, explain a change in the domestic figures.)

The years that count

A comparison headed 2015–2025, like the Eton and Westminster one below, promises eleven years and may deliver far fewer, naming the years it uses and giving a reason for each one it drops. Results may be missing, count different qualifications or come from publications that disagree, and what survives, consecutive or not, are the years in which both schools have figures that can fairly be compared. A missing year can’t be mended by borrowing its neighbour, and a publication summarising several years belongs to the whole period, since slicing it into annual results would manufacture figures nobody published.

No moving the goalposts

The annual differences come first. Given enough comparable evidence, the comparison then checks the whole period, the latest three and five comparable years, and what happens when each year in turn is left out. It is a fixed list, so nobody can go trawling through every choice of dates for the flattering one; Test a claim explores the wider set of year ranges separately. When a definition changes, the years on either side are examined apart, because folding them into one middle difference, or median, would hide the change itself. And sometimes the most useful conclusion is also the least exciting, that there aren’t enough comparable years to answer the question.

Where a pattern leads

The most interesting patterns send you back for a second look. Does this one appear in the broader grade bands, and is the newest result provisional? Have application numbers changed, or the pupils included? Whichever of those matters to the comparison is the detail to follow, since a pattern can last for years and still keep its causes to itself.

Eton and Westminster: A-level grades at A*, 2015–2025

Share of published A-level entries awarded A* in the named examination year.

Eton’s recorded result was typically 8.7 percentage points lower than Westminster’s across 3 shared years (2017, 2019, 2025). “Typically” means the median of the annual differences.

Where these figures come from

Each record gives the full definition, the documents it came from and what we checked.

  1. Eton College: Leaver destinations, 2000–2015, 2015

    The earlier source uses a final leaver-destination basis.

    We have not yet identified this figure’s source well enough to check the original. The research references are available in Record details.

  2. Eton College: Oxbridge destination counts, later years, 2025

    The field’s published basis identifies apply-centre acceptances; not substituted for the earlier destination measure.

    We have not yet identified this figure’s source well enough to check the original. The research references are available in Record details.

  • The two examples count different outcomes, so we neither subtract one from the other nor join them into a single trend.
  • A lack of statistical significance is no proof of institutional resilience, and no regression results from the older dossier are imported here.
About this answer

Written by The Schools Record from the sources identified above. The earlier research listed below helped us find the questions and passages to examine. Figures in the article come from the current record, so an older research document cannot substitute an earlier number.
