The Cognitive Abilities Test (CAT4) measures students’ reasoning abilities. Understanding these scores helps parents and educators identify academic strengths, pinpoint areas for support, and guide learning pathways.
I’m Liron Katz, an assessment development specialist, and I designed this guide to help you clearly interpret these results and understand what they mean for your child's cognitive profile and potential.
Understanding your child's CAT4 results starts with knowing what each part of the report shows. The sample report below uses fictional data and follows the layout of the individual report that teachers receive. Each part is explained in the order it appears.
The top of the report records the student's year group, test level and exact age on the day of the test. Age matters because every score is calculated by comparing your child with students of the same age in years and months, not with everyone in the year group.
"Students tested" shows how many students sat the test in the same group. This number is needed to understand the group rank.
Each row shows one of the four CAT4 batteries, followed by the mean of all four. The columns are:
Together, these columns show both how your child compares nationally and where they sit within their own school group.
The dot on each line marks the SAS, and the line around it shows the 90% confidence band. No single test sitting is perfectly precise, so the band shows the range in which your child's true score is very likely to fall. In this example, the mean SAS is 109, but the student's true ability is most likely somewhere between about 104 and 114.
The yellow area marks the average range. A dot to the right of the yellow area indicates above-average performance in that battery, and a dot to the left indicates below-average performance. When the bands of two batteries overlap heavily, the difference between those scores may not be meaningful.
The profile compares the verbal and spatial stanines to show whether your child may learn more easily through words or through visual and spatial methods. Profiles are described as a mild, moderate or extreme bias towards verbal or spatial learning, or as an even profile when the two scores are similar.
Here, the spatial stanine (7) is higher than the verbal stanine (5), so the profile shows a mild spatial bias. This suggests the student may find visual explanations, diagrams and hands-on tasks easier than purely verbal instruction. A profile describes a tendency rather than a fixed limit, and teachers use it alongside classroom observation.
Read together, the scores describe a student who is:
With a mean SAS of 109, the student sits towards the top of the average range. The three unanswered verbal questions may be worth discussing with the school.
Not necessarily. The report sent to parents is usually simpler. It shows each battery as below average, average or above average, with a written explanation of the profile and suggestions for support at home. Group rank normally appears only in teacher reports, which may also include indicators of likely future attainment at KS2, GCSE and A level. If you would like to see the detailed scores, you can ask your child's school.
What counts as a good CAT4 score depends on how the result will be used, but every score is measured on the same scale. The chart below shows how Standard Age Scores (SAS) are spread across all children of the same age.
The average CAT4 score is an SAS of 100, which represents typical performance for a child of that exact age. Because every score is adjusted for age, 100 means the same thing in every year group. Just over half of all children (54%) score between 89 and 111, the average range shown in yellow.
Scores become less common the further they are from 100. The stanine bands give a simple guide:
A below-average score does not mean a child lacks intelligence. It can help schools and parents identify where extra support may be useful.
There is no national pass mark for CAT4. Each school sets its own requirements, and some focus on the mean SAS while others look closely at particular batteries, such as verbal or quantitative reasoning. To understand what a school's threshold means, it helps to know how each score compares nationally:
If a school looks for an SAS of 115, for example, your child would need to score higher than roughly 84% of children of the same age. Admissions teams usually consider CAT4 results alongside school reports and interviews, so it is always worth asking the school directly how it uses the scores.
There is no single national threshold for gifted and talented programmes, and schools set their own criteria. The following ranges are often used as a guide:
Because a high score in a single battery can be enough for a child to be identified, it is worth looking at each battery, not just the mean SAS.

A good CAT4 score is the same in every year group. An SAS of 100 is average whether your child is in Year 5, 6 or 7, and the same bands apply at every age: 112 and above is above average, 89 to 111 is average, and 88 and below is below average. A Year 5 child with an SAS of 110 has performed just as well, compared with children of the same age, as a Year 7 child with the same score.
The Standard Age Score (SAS) is the most important score in a CAT4 report because it allows children of different ages to be compared fairly.
A child's raw score is adjusted according to their exact age in years and months on the day of the test. This means a younger child is not compared directly with older classmates who may have had more time to develop their reasoning skills.
For example, if two children are in the same class but one was born in September and the other in August, CAT4 takes this age difference into account when calculating their SAS. Each child is compared with other children of the same age rather than with everyone in their year group.
This age adjustment helps ensure that CAT4 results give an accurate picture of a child's reasoning ability, regardless of when they were born.
Each year group sits a level with questions suited to its age:
The questions become harder at each level, but the scores are standardised in the same way. A score of 100 on Level B therefore means the same as a score of 100 on Level D.
Although the scoring is the same, the purpose of the test often differs by stage:
Because schools use results differently, it is worth asking your child's school why the test is being taken and how the scores will be used.
Your child's Standard Age Score (SAS) compares their performance with a nationally representative sample of children of exactly the same age. A score of 100 is the national average, and an SAS means the same thing in every school.
Group Rank (GR) compares your child only with the other students who sat CAT4 in the same group, usually their year group at the same school. A GR of 14 out of 148 means your child placed 14th in that group. It says nothing about how the group performs nationally.
This is why the same SAS can produce very different group ranks. A child with an SAS of 115 might rank near the top of one school's cohort and around the middle of a highly selective one.
Schools use CAT4 scores for several major educational decisions, and each relies on a different score:
Policies vary between schools, so it is always worth asking which score your child's school uses and why.
There is no national pass mark for CAT4. Each school sets its own requirements, and some focus on the mean SAS while others look closely at particular batteries, such as verbal or quantitative reasoning. To understand what a school's threshold means, it helps to know how each score compares nationally:
If a school looks for an SAS of 115, for example, your child would need to score higher than roughly 84% of children of the same age.
International schools, particularly those following a British curriculum, often use CAT4 as part of their admissions process. Because it measures reasoning rather than knowledge of a particular curriculum, it allows schools to compare applicants from different education systems. The non-verbal and spatial batteries also rely less on English, which can help schools assess children who speak English as an additional language. Children usually sit the level that matches their age or year group.
Private and international schools usually consider CAT4 results alongside previous school reports and interviews, so it is always worth asking the school directly how it uses the scores.
Getting ready for the CAT4?
Help your child practise with realistic CAT4 tests and detailed explanations, available for every level.
As well as individual scores, every CAT4 report includes a learning profile. It shows whether your child may find it easier to learn through words or through visual and spatial thinking, and it helps teachers understand how best to support them in class.
CAT4 is made up of four batteries, each measuring a different type of reasoning:
Each battery receives its own SAS, NPR and stanine, so you can see where your child's strengths lie.
The profile compares your child's verbal reasoning and spatial ability results. These two batteries sit at opposite ends of a continuum, with quantitative and non-verbal reasoning combining the two in differing degrees. The profile uses the stanine scores for the two batteries and also takes into account the overall level of ability shown.
Every student's profile falls into one of seven categories:
"Mild", "moderate" and "extreme" describe how large the gap is between the two scores.
A mild spatial bias means your child's spatial ability score is somewhat higher than their verbal reasoning score. They may find it easier to learn from diagrams, models, demonstrations and hands-on tasks than from purely written or spoken explanations.
A mild verbal bias is the reverse. Your child may learn more easily through reading, discussion and written explanation, and may find tasks that rely on visualising shapes or space more challenging.
A mild bias is the smallest category of difference, and many children with a mild bias learn well through both approaches.
A low CAT4 score does not mean a child lacks intelligence. It acts as an early warning system to help schools and parents step in with the right support.
A score can be lower than expected for reasons that have little to do with ability. Common factors include:
If one of these may have affected your child's result, it is worth raising it with the school.
Schools use a low score as a starting point for support rather than a final judgement. Typical steps include:
Asking the school which of these steps it plans to take can help you support the same goals at home.
CAT4 is significantly different from the regular school curriculum, so familiarising your child with the question types before the test is important. To help you prepare, TestPrep-Online offers CAT4 PrepPacks for Levels X-Y (years 2-3), Levels A-B (years 4-5), Levels C-D (years 6-7), Levels E-F (years 8-9) and Level G (16+), each containing sample questions, practice tests and detailed explanations. You can also start with our free CAT4 sample questions.
Not always. Schools decide what to share, and the report for parents is optional. When it is provided, it is simpler than the teacher's report. It shows each battery as below average, average or above average, with an explanation of your child's learning profile and suggestions for support at home. You can ask the school if you would like to see the detailed scores.
Online CAT4 tests are scored automatically, so schools can access the results immediately. Paper tests are sent to GL Assessment for scoring, and the reports are returned to the school within 15 working days. Schools then decide when, and how much, to share with parents.
No. CAT4 has no pass or fail mark. An SAS of 100 is the national average for your child's age, and each school sets its own threshold when it uses CAT4 for admissions or gifted programmes. Some schools look at the mean SAS, while others focus on particular batteries, so it is worth asking how your child's school uses the scores.
The highest possible CAT4 SAS is 141, and the lowest is 69. Scores far from the average are rare: only about 4% of children score 127 or above, which places them in stanine 9. Because every score is adjusted for age, the same scale applies to every year group.
