11+ standardised score calculator

Turn a practice paper score into an estimated 11+ standardised score, adjusted for your child's age, the same way we do in our parent reports.

Your child's score

We assume one mark per question.

How the calculator works

What is a standardised score?

11+ results aren't given as marks. They're turned into standardised scores, where 100 is average for children of the same age. Most children score between 85 and 115, and scores usually run from 69 to 141. This lets schools compare children fairly, even across different papers.

Why age matters

A child born in August can be nearly a year younger than a classmate born in September. Standardisation allows for this: we take about 10½ as the typical age for the 11+, and each month younger adds a little to the score (each month older takes a little off), up to 12 points either way.

Why a range?

One paper can't pin a score down exactly. The range is wider for short papers and when you're not sure how hard the paper was. Qualifying scores differ by school, so check the test your school uses.

Want a score you can track over time?

Try a free sample paper. When your child finishes a paper on Academy11+, you get their estimated standardised score automatically, and it gets more accurate as more children sit the same paper.

Questions parents ask

What is a standardised score in the 11+?

A standardised score puts every child on the same scale, whatever the paper. 100 is the average for children of the same age, and most children score between 85 and 115. Scores usually run from about 69 to 141. Grammar schools use these scores, not raw marks, to decide who qualifies.

Why does my child's age change the score?

Children in the same school year can be almost a year apart in age, and the oldest have had more time to learn. Standardisation evens this out: a younger child gets a few extra points for the same raw mark, and an older child a few less. This calculator uses about 10 years 6 months as the typical age for sitting the 11+.

How accurate is this calculator?

It is an estimate. Real standardised scores are worked out from how every child who sat the same paper did, which nobody outside the exam board knows in advance. We compare your child's mark with how children typically score on a paper of that difficulty, then show a range rather than a single number. Treat it as a guide to where your child is, not a prediction of their result.

What standardised score do you need to pass the 11+?

There is no single pass mark. Each grammar school or area sets its own qualifying score, and some schools then rank children by score when they have more applicants than places. Check the admissions information for the schools you are interested in; our grammar school pages show which test each school uses.

What if I don't know how hard the paper was?

Choose "Not sure". We then work out the score for an easy, a medium and a hard paper and show a range that covers all three, so the range is wider. If the paper came from a book or website that gives a difficulty level, choosing it will give a tighter estimate.
