Scaled scores are the source of more parental confusion than any other part of the 11+. Practice papers come back with raw marks like 36/50; the live test reports a single number like 122; the qualifying score in your region might be 121, or 320 across three subjects, or "the top 25% of the cohort". This page explains, in plain language, how the system actually works.
What is a scaled score?
A scaled score is a child's raw score adjusted for two things. First, age — within a single school year, the oldest child can be eleven months older than the youngest, which at age ten is a meaningful gap. Age standardisation gives a small uplift to younger children to remove that advantage. Second, cohort difficulty — if a particular paper turns out to be slightly harder than expected, the conversion from raw to scaled is slightly more generous, and vice versa. The combination produces a number that can be compared fairly across children and across years.
The 69–141 scale
Most regions report 11+ scaled scores on a scale that runs from 69 (lowest) to 141 (highest), with 100 representing the average performance of the cohort. The qualifying score — the threshold for grammar school entry — varies by region but typically sits between 111 and 121. A score of 121 means the child performed roughly in the top 15% of their cohort; a score of 111 means roughly the top 30%. The scale is deliberately compressed at the top: the difference between scoring 130 and 141 is enormous in raw terms but appears small on the scale.
How regions combine subject scores
Some regions report a single combined scaled score; others report three subject scores and apply weighting. Kent, for example, has historically published three scores (English, Maths, Reasoning) with the qualifying threshold defined as a combined total. Buckinghamshire publishes a single overall standardised score. Birmingham's KEVI consortium publishes a single score derived from a CEM-style mixed test. Always check your specific region's published methodology — it changes occasionally.
Translating practice raw scores into expectations
The honest answer is: imperfectly. Practice papers do not have the same standardisation engine behind them, and a raw score of 38/50 on a practice paper does not map cleanly to a scaled score of 121 on the live test. As a working rule of thumb:
- Below 60% raw, the live scaled score is unlikely to qualify.
- 60–75% raw, the live scaled score will be in the qualifying band but the result will depend heavily on age and cohort difficulty.
- Above 80% raw, the live scaled score is very likely to qualify, with a comfortable margin.
These are bands, not promises. A child who consistently scores 85% across multiple papers and subjects is in a strong position; one who scores 85% on one paper and 50% on the next is not.
Age standardisation in practice
The age uplift is small but not negligible. A summer-born child (August) typically receives a several-point uplift over a September-born child of identical raw performance. This is fair — the alternative would systematically penalise a third of the cohort for being younger — and it should remove rather than create anxiety for parents of summer-born children.
What scaled scores don't measure
Scaled scores do not measure long-term academic potential. They measure performance on a particular morning, on a particular paper, in a particular subject mix. Many children who don't qualify go on to thrive in excellent comprehensive schools; many who do qualify find that grammar school is not the right fit for them. Hold the score lightly, in both directions.
Where to look for your region's qualifying score
Each local authority publishes its qualifying score in the autumn after the test is sat. The most reliable source is your local authority's school admissions page; the next most reliable is your target grammar school's own admissions PDF. Forum chatter is unreliable, especially in the days immediately after results are released.
