What is the Highest 11 Plus Score?

If your child is preparing for the 11 plus, you are probably wondering what the scores mean, what counts as a good result, and how high your child needs to aim.

The highest 11 plus score a child can achieve is a standardised age score (SAS) of 142. This places them in the top 1% of all children taking the test. The average score is 100, and most grammar schools use a qualifying score of around 121 as their pass mark. A score of 120 or above is generally considered a strong result, putting your child in the top 10% of their year group. 

What is the highest 11 plus score?

The highest score your child can achieve in the 11 plus is a standardised age score (SAS) of 142. This is the top of the scale used by the major exam providers, including GL Assessment, and it represents the very top 1% of all children who sit the test.

At the other end of the scale, the lowest possible SAS is around 60. The average, the score that represents the middle of the year group, is 100. Here is how the full scale breaks down:

How is the 11 plus score calculated?

This is one of the most common questions parents ask, and it is a fair one, because the scoring system is not as straightforward as it might first seem.

Your child's final 11 plus score is not simply the number of questions they got right. It goes through two stages before becoming the number you see on the results letter.

Step 1: Raw score

When your child sits the exam, their papers are marked, and they receive a raw score, the total number of marks they earned across all sections. Different papers have different total marks, so the raw scores from each subject are combined and weighted to ensure every subject contributes equally to the final result.

Step 2: Standardised age score (SAS)

The raw score is then converted into a standardised age score using a standardisation table. This is the crucial step, and it is the reason the 11 plus is considered fairer than a simple marked exam.

Here is why standardisation matters. Children in the same school year can be almost 12 months apart in age. A child born in September will have had nearly a full extra year of learning compared to a child born in August. Without standardisation, older children would have a significant built-in advantage.

To make things fair, the exam board uses your child's exact age in years and months on the day of the exam. Younger children receive a small boost to their raw score as part of the standardisation. The result is a score that reflects your child's ability relative to their age, not just an absolute mark.

What is a good 11 plus score?

The honest answer is: it depends on which school you are applying to. But here are the benchmarks that most families use to gauge where their child stands.

A score of 120 or above is generally considered a strong result. It places your child in the top 10% of all children in their year group, and it meets or exceeds the qualifying mark at the majority of grammar schools across England.

For the most competitive grammar schools, including those in highly selective areas like Sutton, Reading, or Birmingham, you may need 130 or higher to be confident of securing a place, especially if demand for spaces significantly outstrips supply.

As a general rule:

• 115 or above - a solid score that meets the threshold at many grammar schools.

• 120 or above - a strong score that puts your child in the top 10% and is competitive at most schools.

• 125 or above - a very strong score, competitive at the majority of selective schools.

• 130 or above - an excellent score, needed for the most selective grammar schools and for highly competitive areas.

What is the 11 plus pass mark?

There is no single national pass mark for the 11 plus. Each grammar school or consortium sets its own qualifying score, and it can change from year to year depending on how the cohort performs.

Most schools use one of two approaches:

• A fixed qualifying score - the school sets a standardised score (e.g., 121) that a child must reach to be considered. If more children than there are places meet this threshold, the school uses admissions criteria (such as distance from the school) to allocate places.

• A ranked system - the school ranks all applicants from highest to lowest score and offers places to the top-scoring children until all spaces are filled. This means the effective pass mark changes each year depending on how all the children in that intake performed.

The commonly cited pass mark of 121 is a useful general target, but please do not treat it as a fixed rule. A child who scores 121 might comfortably get into a grammar school in one area but not make the cut in another, more competitive region.

What percentage of pupils pass the 11 plus?

Nationally, around 30% of pupils who sit the 11 plus achieve a qualifying score. But this figure varies widely by region and by the number of grammar school places available locally.

Around 100,000 pupils sit the 11 plus in England each year. There are 163 grammar schools across 35 local authorities. In the 11 local authorities classed as "highly selective", where more than 25% of children attend grammar schools, the pass rate is much higher simply because there are more places to fill. These areas include Kent, Buckinghamshire, Lincolnshire, Trafford and Wirral, among others.

In contrast, in London boroughs where grammar school places are scarce, the competition is fierce. In some parts of London, more than 30 children are competing for every single place at a grammar school.

How to help your child score higher in the 11 plus

Understanding the scoring system is one thing, but what actually makes the difference to your child's result? Here are the most effective steps you can take.

1. Start early, build steadily

Begin preparing in Year 5, around 12 to 18 months before the exam. Short daily sessions of 20 to 30 minutes are far more effective than cramming. Our 11 plus tuition is built around this gradual, confidence-first approach.

2. Know your target school's mark

Before setting a score target, research the qualifying score for your specific target school. A score that earns a place in one area may not be enough in another. Aim for at least 5-10 points above the qualifying mark to give yourself a buffer.

3. Practise with realistic mock tests

Timed practice builds exam technique and shows your child exactly what the real test feels like. Our 11 plus mock exams use the same format as the real exam, giving your child genuine, measurable feedback on where they stand.

4. Track progress through standardised scores

When your child takes practice papers, look at the standardised score, not just the raw mark. The SAS is the number that matters in the real exam and it gives you a true picture of progress over time.

5. Work with a specialist tutor

A tutor who knows the 11 plus format can identify exactly where your child is losing marks and fix those gaps quickly. Our 11 plus tutors provide personalised, targeted support that general revision simply cannot replicate.

6. Boost with intensive preparation

If the exam is approaching and your child needs to close a gap, our 11 plus intensive courses provide a structured, focused push in the final weeks, covering every subject area tested and building real exam confidence.

Final thoughts

The highest 11 plus score is 142, but chasing the maximum is not the point. What matters is understanding what score your child needs for their specific target school and then preparing consistently and smartly to achieve it.
