Quick answer

A standardised score is a converted 11+ result, not the number of questions answered correctly. It may account for the test cohort, the child's age, paper difficulty or subject weighting. The safe reading is route by route: what does this score allow the named school to do?

  • Raw marks and standardised scores are different numbers.
  • Age standardisation can adjust results so younger children in the school year are not unfairly compared with older children.
  • A standardised score still needs the school policy beside it before it can inform CAF decisions.

Raw Mark, Standardised Score, Qualifying Score

These terms are often mixed together in conversation, but they do different jobs.

Raw mark

Meaning
The mark earned on the paper before conversion.
Parent reading
Rarely enough on its own, because routes normally report a converted score or outcome.

Standardised score

Meaning
A converted score placed on the route's scoring scale.
Parent reading
Read it with the route explanation, not as a percentage.

Age-standardised score

Meaning
A score adjusted to account for age differences within the test cohort.
Parent reading
Common in 11+ routes where children sit the test at different ages.

Qualifying score

Meaning
The score or standard needed to be considered selective or eligible.
Parent reading
It may open consideration without deciding the actual school offer.

Rank

Meaning
The child's position in an ordered group.
Parent reading
Some schools use rank heavily; others do not use score as the main allocation rule.

The short parent answer is already covered in what is a standardised score. This guide gives the fuller version for results season.

Why The Same Number Can Mean Different Things

A score of 121 in Buckinghamshire, a Bexley age-standardised score and a Sutton SET outcome do not belong on one shared scale. Each route defines what its result means.

For example:

The route, not the number alone, gives the score meaning.

How Age Standardisation Fits In

Children in a school year can be almost a year apart in age. Age standardisation is designed to reduce unfair comparison caused by that age gap. It does not mean every route uses the same formula or publishes the same level of detail.

The main checks are:

  • Does the route say scores are age-standardised?

    Many 11+ routes do, but the official route page is the source to read.

  • Is the result a component score or total score?

    Kent, Bexley and other routes may report sections, totals or outcome categories differently.

  • Is there a qualifying threshold?

    Some routes publish a clear threshold. Others use school-level or staged wording.

  • Does the school use score after qualification?

    In some policies, higher score can matter. In others, catchment, distance or priority groups matter more.

Standardised Score And CAF Decisions

A result can change the school list, but it should not replace the school policy.

Before using a score to order the CAF, read:

Mistakes To Avoid

  • Do not convert the score into a percentage

    A standardised score is already a converted result.

  • Do not compare routes as if the scale is national

    Different routes use different tests, cohorts and policies.

  • Do not treat a high score as an offer

    Even a strong score needs the named school's allocation rules.

  • Do not ignore weak component scores

    Some routes require both a total threshold and minimum section scores.

Score Reading Workflow

  1. Read the route score explainer

    Open the score page for the actual route rather than relying on another area's threshold. Open score explainers.

  2. Separate pass mark from offer chance

    The qualifying line and the allocation rule are often different parts of the process. Read pass marks guidance.

  3. Open the school policy

    Check whether the named school uses score, rank, distance, catchment or priority groups after qualification. Read policy guidance.

  4. Build the CAF from real preference

    Use the score as evidence, then order schools by preference and realistic admissions rules. Read CAF strategy.
