Has your child’s school mentioned an upcoming CAT4 test? If you’re a parent, particularly in the UK or at a British international school, you may be wondering exactly what this assessment involves.
This guide is designed to answer all your questions, explaining what the Cognitive Abilities Test (CAT4) measures, how to interpret the results, and how it helps create a supportive and personalised learning environment for your child.
Key Takeaways
- The CAT4 test measures a student’s reasoning ability and academic potential, not their knowledge of the curriculum.
- It assesses four distinct areas: Verbal, Quantitative, Non-Verbal, and Spatial reasoning to create a complete cognitive profile.
- There is no “pass” or “fail.” The results are used by schools to understand a student’s individual learning style and provide tailored support.
- The main score, the Standard Age Score (SAS), compares your child to the national average, with 100 being the mean.
What Is the CAT4 Test?


The Cognitive Abilities Test (CAT4), developed by GL Assessment, is a widely used assessment for children aged 6 to 17.
Unlike a typical maths or English exam, CAT4 doesn’t focus on what a child has memorised in class. Instead, it looks at how they naturally think, reason, and approach different types of problems.
In simple terms, it helps answer questions like:
- How does this child learn best?
- What are their natural strengths?
- Where might they benefit from extra support?
For teachers, CAT4 offers a clearer picture of each student’s potential and learning style. For parents, it provides helpful insights that go beyond day-to-day schoolwork.
Because of this, CAT4 can highlight strengths that might not always be obvious in the classroom, while also gently identifying areas where a child may need more support.
Overall, it plays an important role in helping schools create a more personalised and supportive learning experience for every child.
The Four Abilities Measured by the CAT4 Test


The CAT4 provides a holistic view of a student’s abilities by breaking down its assessment into four distinct batteries. Understanding what each one measures can help you appreciate your child’s unique cognitive strengths.
1. Verbal Reasoning
This battery assesses a student’s ability to reason with words. It is a strong indicator of potential in subjects that require strong language skills, such as English, History, and Humanities.
- Verbal Classification: Involves identifying the conceptual link between a set of words.
- Verbal Analogies: Requires understanding the relationship between a pair of words and applying that same relationship to a different pair.
2. Quantitative Reasoning
This section measures the ability to reason with numbers. It is not a test of mathematical calculation but rather a test of a student’s capacity to understand numerical relationships and solve problems. This is a key indicator for success in STEM subjects like Maths and the Sciences.
- Number Series: Asks students to identify the rule in a sequence of numbers.
- Number Analogies: Similar to verbal analogies but using numerical relationships.
3. Non-Verbal Reasoning
This battery uses shapes and patterns to assess problem-solving skills without relying on words. This makes it an excellent way to understand the potential of students with English as an Additional Language (EAL) or those with language-related learning difficulties. It highlights a student’s ability to think logically and see patterns.
- Figure Classification: Involves identifying a common feature among a group of shapes.
- Figure Matrices: Requires completing a grid of shapes based on a logical pattern.
4. Spatial Ability
Spatial Ability assesses a student’s capacity to visualise and mentally manipulate 2D and 3D shapes. This skill is vital for success in practical and technical fields like Engineering, Architecture, Design Technology, and many scientific disciplines.
- Figure Analysis: Tests the ability to visualise a folded and hole-punched piece of paper when it is unfolded.
- Figure Recognition: Involves finding a specific shape hidden within a complex pattern.
How to Understand Your Child’s CAT4 Scores


Your child’s CAT4 report will include several numbers and terms that create a detailed learning profile. Here’s a simple breakdown of the most common scores:
- Standard Age Score (SAS): This is the most important score. It compares your child’s performance to a large, nationally representative sample of students of the exact same age. The average SAS is 100. A score of 126 or above suggests a very high ability, while a score of 74 or below indicates that extra support may be needed.
- National Percentile Rank (NPR): This shows how your child performed as a percentage. For example, an NPR of 80 means your child scored higher than 80% of students in their age group.
- Stanines (ST): This simplifies the score onto a nine-point scale. Stanine 5 represents the average range, while 9 is the highest and 1 is the lowest.
The different test versions, known as CAT4 Levels (from Level X to Level G), are tailored to specific school year groups to ensure the questions are age-appropriate.
Why Do International Schools Use CAT4?


Proactive and supportive schools use CAT4 results not to label students, but to unlock their potential. The data provides a roadmap for teachers to optimise their instructional strategies for every child.
At leading international schools like The ABC International School (ABCIS), the CAT4 is a cornerstone of a holistic educational approach. Our academic teams use the insights to:
- Personalise the Learning Experience: If a student’s profile shows a strong spatial ability but a weaker verbal one, teachers can use more visual aids and diagrams to explain complex concepts, making learning more accessible and effective.
- Identify Gifted Students and Support Needs: The test helps identify students who would benefit from gifted and talented programmes, as well as those who might have underlying learning challenges that aren’t immediately obvious in class.
- Guide Future Academic Pathways: For older students, the CAT4 profile is an invaluable tool in conversations about IGCSE and A-Level subject selections, helping them choose subjects that align with their natural aptitudes and future university ambitions.
- Build Student Confidence: By understanding and celebrating a child’s cognitive strengths, we empower them to succeed in areas where they are naturally gifted, fostering a positive and confident approach to their education.
How to Help Your Child Prepare for the CAT4 Test
The most important thing for parents to know is that the CAT4 is designed to be “tutor-proof.” Intensive revision or cramming is ineffective because it assesses reasoning skills, not learned facts. The best preparation is to foster a stimulating environment that encourages these skills naturally.
- Encourage Reading for Pleasure: This builds vocabulary and verbal reasoning skills.
- Play Logic and Strategy Games: Board games, puzzles, Sudoku, and building with LEGO all help develop non-verbal reasoning and spatial ability.
- Discuss Everyday Maths: Involve your child in real-world problem-solving, such as calculating discounts, measuring ingredients, or managing pocket money.
- Focus on Well-being: Ensure your child has a good night’s sleep before the test and a healthy breakfast. A calm, positive mindset is far more beneficial than last-minute practice.
- Reassure Your Child: Remind them that this is not a test with a “pass” or “fail” grade. It’s simply a tool for the school to learn how to help them best.
Supporting Your Child’s Potential with Confidence


The CAT4 test offers valuable insights into how students think, learn, and grow. For parents, it provides reassurance that schools are looking beyond exam results to understand each child more fully.
At The ABC International School (ABCIS), this approach helps create a supportive environment where every student is encouraged to develop with confidence and curiosity.
If you are considering an international education for your child, understanding assessments like CAT4 is a helpful step towards making an informed decision.

Frequently Asked Questions (FAQ)
There is no such thing as a “good” or “bad” score. The average Standard Age Score (SAS) is 100. A score above this indicates above-average reasoning ability in a particular area, and a score below suggests the student may need more support. The value lies in the overall profile of strengths and weaknesses, not a single number.
While some selective secondary schools use the CAT4 as part of their 11+ admissions process, its primary purpose within most schools is to understand an enrolled student’s learning profile. At The ABC International School (ABCIS), for instance, it is used to support and challenge students already in our community.
No. The test is designed to assess innate ability, and the questions are unfamiliar. While some familiarity with question styles can reduce anxiety, the best preparation is to develop underlying cognitive skills through puzzles, reading, and problem-solving activities.
While the CAT4 measures cognitive abilities similar to traditional IQ tests, its focus is educational. The goal is not to produce a single IQ number but to provide a detailed profile of a student’s learning preferences to inform teaching strategies.
The full test consists of several short, timed subsections. The total testing time is approximately 72 minutes, usually split into two or three sessions to ensure students can maintain focus.
CAT4 results do not directly influence grades. Instead, they provide context. For example, if a student with a high Quantitative Reasoning score is underperforming in Maths, it prompts the teacher to investigate whether the teaching method or another factor is creating a barrier to learning, rather than assuming the student lacks ability.
