KS2 SATs scaled score converter

There's no fixed pass mark for KS2 SATs — a scaled score of 100 or more means the expected standard was met, but the raw mark needed for 100 changes every year.

Enter a raw mark for any year from 2016 to 2026 and see the exact scaled score, using the official DfE conversion tables.

In 2026, a raw score of 56 or more in Maths was needed to meet the expected standard (out of 110).

Why there's no fixed pass mark

KS2 SATs papers change every year, and no two years are exactly the same difficulty. If a fixed raw-mark pass mark were used, a slightly harder paper would fail more children through no fault of their own. Instead, the STA sets the raw-to-scaled conversion after marking is complete each year, calibrated so that a scaled score of 100 always represents the same expected standard — however that year's raw marks happened to fall.

That's why the raw score needed for 100 moves around from year to year — sometimes by several marks — even though what "100" means never changes.

Raw score thresholds by year

The raw mark needed to reach the expected standard (scaled score 100) and greater depth (scaled score 110), for every year and subject.

Frequently asked questions

What raw mark do I need for a scaled score of 100?
It changes every year, because the papers themselves vary slightly in difficulty — the STA recalculates the threshold annually. Select a year and subject above, or check the reference table below, to see the exact raw score needed for that year.
What is a good SATs score?
Any scaled score of 100 or above means a child met the expected standard for their age — that's the benchmark the test is built around, not a pass/fail line. A score of 110 or above is greater depth, meaning attainment beyond the expected standard. There's no such thing as a 'perfect' score children are expected to reach; 100+ is the target the vast majority of children are aiming for.
Is 99 a good SATs score?
A scaled score of 99 is one point below the expected standard (100), so it's recorded as 'working towards' rather than 'met' the expected standard. In practice it's very close — often just one or two raw marks short of 100 — and is not treated as a concerning result on its own. Schools use it to flag a specific area worth a bit more support, not as a marker of failure.
Why is there no fixed pass mark for SATs?
Because papers aren't identical from year to year, a fixed raw-mark pass mark would make some years' tests effectively harder or easier to pass. The scaled score system re-calibrates each year's raw marks so that 100 always represents the same expected standard, regardless of that year's exact paper difficulty.
Where do these conversion tables come from?
Directly from the official Standards and Testing Agency (STA) scaled score conversion tables published by the Department for Education after each year's tests.
