What Is the CAT4 Test? A Complete Guide for Parents
The CAT4 — short for the Cognitive Abilities Test, 4th Edition — is a standardised assessment developed and published by GL Assessment, one of the leading providers of educational assessments in the world. Used by thousands of schools across the United Kingdom, the Middle East, Asia, and beyond, the CAT4 test is designed to evaluate a student's cognitive abilities and learning potential rather than their knowledge of any particular subject.
Unlike academic examinations such as SATs, GCSEs, or end-of-term tests, the CAT4 assessment does not test what a child has already learned. Instead, it measures how a child thinks — how they process information, solve problems, and reason through unfamiliar challenges. This makes it an especially valuable tool for schools that follow the British curriculum or the International Baccalaureate (IB) framework, as it provides a fair and objective snapshot of a student's underlying abilities, independent of their educational background or native language.
For parents, understanding the CAT4 test is essential. Whether your child is applying to a selective school, transitioning between year groups, or simply being assessed as part of their current school's evaluation process, knowing what the test involves — and how to help your child feel prepared — can make a real difference to their confidence and performance.
What Does the CAT4 Test Measure?
At its core, the CAT4 assessment measures reasoning and thinking skills across four distinct cognitive domains, known as batteries. Each battery targets a different aspect of how a student processes information. Together, the four batteries provide a comprehensive profile of a child's cognitive strengths and areas for development.
Because the CAT4 focuses on reasoning ability rather than curriculum content, it is often described as a test of potential rather than achievement. A student who performs well on the CAT4 may not necessarily have the highest grades in class — but their results suggest they have strong underlying cognitive abilities that, with the right support, could translate into excellent academic performance.
This distinction is particularly important for schools. The results help teachers understand whether a student is performing in line with their potential, or whether there may be barriers — such as language difficulties, learning differences, or lack of engagement — that are preventing them from reaching their full capability.
The Four CAT4 Batteries
The CAT4 test is divided into four separate batteries. Each battery contains two or three subtests, and together they provide a well-rounded picture of a student's cognitive profile. Here is a closer look at each one.
Verbal Reasoning
The Verbal Reasoning battery assesses a student's ability to express ideas in words, understand relationships between verbal concepts, and think through problems presented in language. Subtests in this battery include Verbal Classification, Verbal Analogies, and Verbal Similarities. Students are presented with groups of words and must identify underlying patterns, relationships, or the odd one out.
Strong verbal reasoning skills are closely linked to performance in language-heavy subjects such as English, history, geography, and modern foreign languages. A student who scores well in this battery tends to be an effective communicator who can absorb, process, and articulate complex ideas. However, it is worth noting that students for whom English is an additional language may initially score lower in this battery — not because of lower cognitive ability, but simply due to the language demands of the questions.
For parents, the Verbal Reasoning score provides insight into how comfortably your child works with language and concepts expressed in words. If your child scores well here, they are likely to thrive in discussion-based classroom environments and essay-based assessments.
Quantitative Reasoning
The Quantitative Reasoning battery evaluates a student's ability to work with numbers, identify numerical patterns, and solve problems that involve quantitative relationships. The subtests — Number Analogies and Number Series — present students with sequences and relationships between numbers that they must analyse and extend.
This battery does not require advanced mathematical knowledge. Students are not being tested on their ability to perform long division or solve algebraic equations. Instead, the focus is on numerical reasoning: the ability to see patterns, make logical deductions, and apply rules to unfamiliar number-based problems. Think of it as testing mathematical thinking rather than mathematical skill.
A strong Quantitative Reasoning score is a good indicator of potential in mathematics, science, and technology-related subjects. For parents wondering whether their child has a natural aptitude for STEM subjects, this battery is one of the most informative measures available.
Non-Verbal Reasoning
The Non-Verbal Reasoning battery is often considered the most culture-fair section of the CAT4 test. It uses shapes, patterns, and figures rather than words or numbers, which means it is less influenced by a student's language background or prior education. Subtests include Figure Classification and Figure Matrices, where students must identify rules governing sequences or groups of abstract shapes and apply those rules to select the correct answer.
This battery measures problem-solving ability in its purest form. It assesses how well a student can identify patterns, think logically, and work through unfamiliar visual problems without relying on language or numerical skills. Because of its culture-fair nature, the Non-Verbal Reasoning battery is sometimes given extra weighting by international schools when assessing students from diverse linguistic backgrounds.
For parents, a strong Non-Verbal Reasoning score indicates that your child is an effective problem-solver who can think independently and adapt to new challenges — skills that are valuable across every area of the curriculum and beyond.
Spatial Ability
The Spatial Ability battery measures a student's capacity to mentally manipulate two-dimensional and three-dimensional shapes. Subtests include Figure Analysis — where students must determine how a folded and hole-punched piece of paper will look when unfolded — and Figure Recognition, where students identify a target shape hidden within a complex design.
Spatial reasoning is a skill that underpins success in a wide range of disciplines, particularly those involving design, engineering, architecture, computer science, and the physical sciences. Students with strong spatial abilities tend to excel at visualising concepts, understanding diagrams, and working with models — whether physical or digital.
Of the four batteries, Spatial Ability is the one that many students find the most unfamiliar, simply because spatial reasoning tasks are less commonly encountered in everyday schoolwork. This makes it a particularly valuable area to practise before taking the CAT4 assessment, as familiarisation can lead to meaningful score improvements.
CAT4 Test Levels
The CAT4 is not a single, one-size-fits-all test. It is available in multiple levels, each designed for a specific age range. This ensures that the difficulty and content of the questions are appropriate for the developmental stage of the student being assessed. The following table shows the nine CAT4 levels, along with the corresponding age ranges and year groups.
| Level | Age Range | Year Group |
|---|---|---|
| X | 6–7 | Year 2 |
| Y | 7–8 | Year 3 |
| A | 8–9 | Year 4 |
| B | 9–10 | Year 5 |
| C | 10–11 | Year 6 |
| D | 11–12 | Year 7 |
| E | 12–13 | Year 8 |
| F | 14–15 | Years 9–10 |
| G | 16–17+ | Years 11–13 |
Most international schools administer the CAT4 at Levels A through F, which cover the primary and secondary school years. The level your child sits will depend on their age at the time of the test, not their year group — although these usually align closely.
An important feature of the CAT4 is that it is age-normed. This means that a student's raw score is compared against a large reference group of students of the same age, ensuring that the final scores reflect ability relative to peers. A 9-year-old and a 12-year-old would never be compared directly, as they sit different levels with different difficulty settings and different norm tables.
How Is the CAT4 Scored?
Understanding CAT4 scores can feel confusing at first, as the results use several different scales. The two most important measures are the Standard Age Score (SAS) and the Stanine.
Standard Age Score (SAS)
The Standard Age Score is the primary metric reported for each of the four batteries and for the overall CAT4 result. It has a mean of 100 and a standard deviation of 15, which means the vast majority of students (roughly 68%) will score between 85 and 115. Scores can range from approximately 60 at the lower end to 140 or above at the upper end. An SAS of 100 indicates that a student is performing exactly at the average level for their age group.
Stanine Scale
The Stanine (short for "standard nine") is a simpler, compressed scoring scale that ranges from 1 to 9, with a mean of 5 and a standard deviation of 2. Stanines provide a quick way to categorise a student's performance into broad bands. The following table shows how stanines relate to SAS scores and percentile ranks.
| Stanine | SAS Range | Percentile | Description |
|---|---|---|---|
| 1 | Below 74 | 1–4% | Very low |
| 2 | 74–81 | 4–11% | Below average |
| 3 | 82–88 | 11–23% | Below average |
| 4 | 89–96 | 23–40% | Average |
| 5 | 97–103 | 40–60% | Average |
| 6 | 104–111 | 60–77% | Above average |
| 7 | 112–118 | 77–89% | Above average |
| 8 | 119–126 | 89–96% | Well above average |
| 9 | 127+ | 96–99% | Very high |
Many selective schools look for an overall SAS of 110 or above (stanine 6–7) as a minimum threshold, while highly competitive schools may expect scores of 120 or higher (stanine 8–9).

Which Schools Use the CAT4?
The CAT4 is one of the most widely used cognitive ability assessments in the world, administered by over 6,000 schools globally. It is particularly prevalent in British curriculum and IB international schools, where it serves as a standardised, objective measure that complements academic records and teacher assessments.
Regions Where the CAT4 Is Most Common
In the United Kingdom, the CAT4 is used extensively in both state and independent schools. Many grammar schools and selective academies use CAT4 results as part of their admissions process, and it is frequently administered at the start of Year 7 to establish baseline ability data for incoming students.
Internationally, the CAT4 has become the assessment of choice for British curriculum schools in the Middle East, particularly in Dubai and Abu Dhabi. Major school groups such as GEMS Education and Taaleem use the CAT4 widely across their portfolios. In Singapore, leading international schools including UWCSEA and Tanglin Trust School incorporate the CAT4 into their admissions and placement processes. And in Hong Kong, the English Schools Foundation (ESF) network is among the prominent users.
How Schools Use CAT4 Results
Schools typically use the CAT4 assessment for one or more of the following purposes:
- Admissions screening — to identify students whose cognitive profile suggests they will thrive in the school's academic programme.
- Class placement and streaming — to group students by ability level in core subjects such as maths, English, and science.
- Identifying gifted and talented students — high CAT4 scores can flag students who may benefit from extension programmes or advanced learning opportunities.
- Learning support identification — a significant gap between CAT4 scores and academic performance can indicate underlying learning difficulties that warrant further investigation.

How to Prepare for the CAT4 Test
One of the most common questions parents ask is whether it is possible — or even advisable — to prepare for the CAT4. The short answer is yes. While the CAT4 is a cognitive abilities test rather than a knowledge-based exam, research and experience consistently show that familiarisation with the question formats can meaningfully improve a student's confidence and performance.
Think of it this way: if a student encounters Figure Matrices or Number Analogies for the very first time under timed exam conditions, they are at a disadvantage compared to a student who has practised similar questions beforehand. The underlying cognitive ability may be the same, but the prepared student can focus entirely on the reasoning task rather than trying to understand the question format at the same time.
Effective Preparation Strategies
Here are the most effective approaches to preparing for the CAT4 test:
- Familiarise your child with all four question types. Make sure they have seen and practised examples from each of the four batteries — Verbal Reasoning, Quantitative Reasoning, Non-Verbal Reasoning, and Spatial Ability — so nothing comes as a surprise on test day.
- Practise regularly with realistic questions. Short, consistent practice sessions (15–20 minutes, several times per week) are more effective than occasional marathon sessions. The key is building familiarity over time.
- Focus on weaker batteries. Most students have a natural cognitive profile — they may be stronger in verbal tasks and weaker in spatial reasoning, for example. Targeted practice in weaker areas can yield the largest score improvements.
- Introduce timed practice. The CAT4 is a timed test, and students who are comfortable working under time pressure perform better. Start with untimed practice to build understanding, then gradually introduce time limits as confidence grows.
- Build confidence, not anxiety. Frame preparation as an opportunity to explore interesting puzzles and challenges, not as high-pressure exam drilling. A positive mindset on test day can make a significant difference.

Frequently Asked Questions
Can you study for the CAT4?
Yes. While the CAT4 is a cognitive abilities test — not a knowledge-based exam — familiarisation with the question formats and regular practice can improve performance. The goal is not to memorise answers but to develop fluency with the types of reasoning tasks the test presents. A student who has practised Verbal Analogies or Figure Matrices will spend less time figuring out what the question is asking and more time actually solving it, which leads to better results.
How long is the CAT4 test?
The full CAT4 assessment takes approximately 2 hours and 15 minutes in total, divided across the four batteries. Most schools do not administer the entire test in a single sitting. Instead, it is typically split across two sessions — often on different days — to reduce fatigue and ensure students can perform at their best. Each battery takes roughly 30 to 45 minutes, including time for instructions.
Is the CAT4 test hard?
The difficulty of the CAT4 is carefully calibrated to the student's age level. A Level B test (for 9–10 year-olds) is genuinely different in content and complexity from a Level D test (for 11–12 year-olds). Within each level, questions progress from easier to more difficult, so every student should be able to answer at least some questions confidently. With proper familiarisation and practice, most students feel comfortable and prepared on test day. The most common source of difficulty is encountering an unfamiliar question type — which is exactly what preparation addresses.
How often can my child retake the CAT4?
Schools typically administer the CAT4 once per admissions cycle or once per academic year as a baseline assessment. Because the test is designed to measure stable cognitive abilities, schools do not generally offer frequent retakes. However, practice tests — such as those available through MindScout — can be taken as often as needed. Regular practice with realistic CAT4-style questions helps your child build familiarity, confidence, and speed, so they are fully prepared when the official test day arrives.
