📚 What Is the CAT4 Test? A Complete Guide for UK School Applicants | 英国CAT4是什么：英国私校申请者完全指南
CAT4 is one of the most widely used cognitive ability tests in the United Kingdom. It is taken by pupils in British schools, by applicants to UK independent schools, and by students in British-curriculum international schools around the world. This guide explains what CAT4 actually measures, how its four modules work, how computer adaptive testing changes the difficulty of the paper in real time, how the report should be read, and how families can prepare sensibly without turning preparation into pointless drilling.
CAT4 是英国使用最广泛的认知能力测验之一，英国本土学校的学生、申请英国私立学校的学生，以及世界各地英式国际学校的学生都可能参加。本文会讲清楚 CAT4 究竟测量什么、四个模块分别怎么考、计算机自适应测试如何实时调整难度、成绩报告应该怎么读，以及家庭应该如何合理准备，而不是把备考变成毫无意义的刷题。
1. What Is CAT4? | CAT4 是什么
CAT4 stands for Cognitive Abilities Test, Fourth Edition. It is produced by GL Assessment, a UK assessment publisher that also supplies reading, spelling and reasoning tests to schools. CAT4 is a standardised test of cognitive ability rather than a test of taught content: it asks how a pupil thinks, not how much of the syllabus that pupil has memorised.
CAT4 的全称是 Cognitive Abilities Test 4th Edition，即“认知能力测验第四版”，由英国 GL Assessment 公司研发。该公司也为学校提供阅读、拼写、推理等测验。CAT4 是一种标准化的认知能力测验，而不是学科知识测验：它考查学生“怎么思考”，而不是“背了多少课程内容”。
The test is designed for pupils from about 5 to 17 years old, and it is used to evaluate cognitive ability, reasoning power and learning potential. The four scores it produces are usually described as verbal, non-verbal, quantitative and spatial, and together they form a profile of a pupil's relative strengths rather than a single judgement about intelligence.
该测验主要面向约 5 岁到 17 岁的学生，用来评估学生的认知能力、思维能力和学习潜力。它输出的四类分数通常被概括为语言、非语言、数学（数量）和空间能力，共同构成学生的学习能力画像，而不是对学生智力下唯一结论。
CAT4 is not a pass-or-fail examination. There is no official pass mark. Instead, a pupil's raw score is converted into a Standard Age Score (SAS) with a mean of 100, and schools compare that score with a large national sample of pupils of the same age.
CAT4 不是“及格／不及格”的考试，官方也没有统一的录取分数线。学生的原始分会被换算成标准年龄分数（SAS），平均值为 100，学校会把它与全国同年龄学生的大样本数据进行比较。
2. Who Takes CAT4, and When? | 谁参加 CAT4，什么时候考
In UK schools, CAT4 is most often administered as a baseline assessment. Many secondary schools test the whole of Year 7 in September, then re-test at the end of Key Stage 3 or before GCSE options. Primary schools may use the lower levels to identify pupils who need extra support or extension.
在英国学校里，CAT4 最常见的用途是“基线测评”。许多中学在 9 月对七年级（Year 7）全体学生进行测试，然后在 Key Stage 3 结束或 GCSE 选科前再测一次。小学也可能使用较低级别，用来识别需要额外支持或需要拔高拓展的学生。
Beyond the state sector, CAT4 is widely used by independent schools. It appears as a screening or entrance test at 11+, 13+ and even 16+ entry, sometimes as a stand-alone assessment and sometimes alongside English, mathematics papers, interviews and a head teacher's report. Because it is delivered online and scored centrally, it is fast and convenient for admissions offices.
在公立体系之外，CAT4 也被私立学校广泛使用。它常作为 11+、13+ 甚至 16+ 入学的筛选或入学考试之一，有时单独使用，有时与英语、数学笔试、面试和校长报告结合使用。由于可以在线施测并由机构统一评分，对招生办来说既快捷又便利。
Because CAT4 is an age-standardised test, a pupil's score is always compared with pupils of the same age in months. This means a younger candidate in a year group is not penalised simply for being younger.
由于 CAT4 是按年龄标准化的，学生的成绩始终与“同年龄（精确到月）”的群体比较。因此，同一班级里年龄偏小的考生不会仅仅因为年龄小而吃亏。
3. The Four Modules at a Glance | 四大模块总览
CAT4 contains four modules, often called batteries. Each battery is made up of two short sub-tests, so a full sitting involves eight short tests in total. The table below summarises what each module examines and the typical question types.
CAT4 包含四个模块（常称为“battery”）。每个模块由两个短测验组成，因此完整测试一共包含八个短测验。下表概括了每个模块的考查重点和典型题型。
| Module 模块 | What it tests 主要考查 | Question types 题型 |
| 语言 Verbal | 词汇理解、语法知识、阅读理解 | Verbal Classification 词语归类；Verbal Analogies 词语类比 |
| 非语言 Non-verbal | 图形理解、形状变换、空间感知 | Figure Classification 图形归类；Figure Matrices 图形矩阵 |
| 数学 Quantitative | 数字理解、计算能力、空间感知 | Number Analogies 数字类比；Number Series 数字序列 |
| 推理／空间 Reasoning | 推理与问题解决能力 | Figure Analysis 折纸分析；Figure Recognition 图形识别 |
A useful rule of thumb is that the first three batteries are heavily loaded with reasoning in words, shapes and numbers, while the fourth battery is the most visual and spatial of all.
一个实用的判断方法是：前三个模块分别以“文字、图形、数字”为载体的推理为主，而第四个模块的视觉与空间成分最强。
4. The Verbal Module | 语言模块：词汇、语法与阅读理解
The verbal battery examines vocabulary, the understanding of grammatical relationships and reading comprehension in the broadest sense. It does not test spelling or punctuation. Instead, it asks pupils to spot the rule that links words together.
语言模块考查的是词汇量、对语法关系的理解，以及广义上的阅读理解能力。它不考拼写和标点，而是要求学生发现词语之间的关联规则。
In Verbal Classification, three words are given that share a hidden category, and the pupil chooses a fourth word belonging to the same category. In Verbal Analogies, a pair of words is presented with the relationship stated, such as 'big is to small', and the pupil completes a second pair with the same relationship.
在词语归类题中，题目给出三个属于同一隐藏类别的词，学生要从选项中选出第四个同类词。在词语类比题中，题目先给出一对词并隐含某种关系，例如“big 对 small”，学生需要用同样的关系补全第二对词。
Vocabulary breadth is the single strongest predictor of success in this module. Wide reading across fiction, non-fiction and news writing builds the word knowledge that the module rewards, and it also supports the comprehension demands of GCSE and A Level study.
词汇广度是这一模块最重要的得分基础。广泛阅读小说、非虚构作品和新闻评论，既能积累该模块所需的词汇，也能为 GCSE 和 A Level 阶段的阅读理解打下基础。
5. The Non-Verbal Module | 非语言模块：图形、形状变换与空间感知
The non-verbal battery removes language almost entirely. Pupils work with shapes, patterns and visual sequences, so the module is particularly useful for identifying able pupils whose first language is not English or who find reading difficult.
非语言模块几乎完全脱离语言，学生面对的是图形、图案和视觉序列。因此，这一模块特别适合识别英语非母语或阅读较弱的“高能力”学生。
Figure Classification presents several figures that follow a common rule, such as the number of sides, the direction of shading or the position of a dot, and the pupil selects the figure that fits the same rule. Figure Matrices present a grid in which one cell is missing, and the pupil must work out the transformation from the completed cells.
图形归类题给出若干遵循同一规则的图形，例如边数、阴影方向或圆点位置，学生需要选出符合同一规则的图形。图形矩阵题给出一个缺格的方阵，学生必须根据已完成的格子推断图形变换规律。
Because the questions are non-verbal, they cannot be solved by translating the problem into words. Pupils who habitually verbalise everything may need practice in scanning figures systematically: count the sides, check the symmetry, track the rotation, then compare.
由于题型是非语言的，学生无法把问题“翻译成文字”来求解。习惯一切靠语言思考的学生，可能需要练习系统化地观察图形：数边数、看对称性、追踪旋转方向，再逐项比较。
6. The Quantitative Module | 数学模块：数字理解、计算与空间感知
The quantitative battery examines number understanding, calculation and spatial perception, but it is not a curriculum mathematics test. Pupils do not need to recall formulae or solve long equations; they need to see how numbers behave.
数学模块考查数字理解、计算能力和空间感知，但它不是课程数学考试。学生不需要背公式或解长方程，而是要看懂数字之间的运行规律。
and ask for the number that completes a second pair in the same way. Number Series present a sequence such as 2, 5, 11, 23 and ask for the next term, where the rule might be 'double and add one'.
数字类比题给出一对具有某种关系的数字，例如 3 → 12，要求学生用同样关系补全另一对数字。数字序列题给出如 2, 5, 11, 23 的数列，要求学生求出下一项，其规则可能是“乘以 2 再加 1”。
For a relation such as doubling, the algebra can be written compactly:
例如“乘以 2 再加 1”这种关系，可以用简洁的代数式表示：
aₙ₊₁ = 2 × aₙ + 1
Strong mental arithmetic helps, but the real skill is flexible thinking: differences, ratios, squares, primes, alternating rules and two-step operations should all be checked quickly when a sequence does not yield an obvious pattern.
扎实的心算能力有帮助，但真正的核心能力是灵活思考：当数列一时看不出规律时，应快速检查差值、倍数、平方数、质数、交替规则以及两步运算。
7. The Reasoning Module | 推理模块：推理与问题解决
The fourth battery is often described by parents as the reasoning module, and it examines reasoning and problem-solving ability through strongly spatial tasks. It is the part of CAT4 that many pupils have never met before in a school classroom.
第四个模块常被家长称为“推理模块”，它通过空间性很强的任务考查推理与问题解决能力。这也是许多学生在日常课堂中从未接触过的部分。
Figure Analysis shows a piece of paper being folded, sometimes twice, then punched with a hole, and asks what the unfolded paper will look like. Figure Recognition shows a complex target shape and asks the pupil to find the identical shape hidden inside or alongside distractors.
折纸分析题展示一张纸被折叠（有时折叠两次）后打孔，要求学生判断展开后的样子。图形识别题则给出一个复杂的目标图形，要求在干扰图形中找到完全相同的那一个。
These tasks measure mental rotation and visual working memory. They correlate well with performance in subjects such as mathematics, physics, design technology and computer science, where a pupil must hold a structure in mind and manipulate it without losing track.
这类任务测量心理旋转能力和视觉工作记忆。它们与数学、物理、设计与技术、计算机科学等学科的表现相关性较高，因为这些学科都要求学生在大脑中保持一个结构并进行操作而不丢失线索。
8. Computer Adaptive Testing Explained | 计算机自适应测试如何运作
CAT4 is delivered using computer adaptive testing, which means the difficulty of the questions changes according to the pupil's performance. Answer correctly and the next question is likely to be harder; answer incorrectly and the test moves to an easier question.
CAT4 采用计算机自适应测试（Computer Adaptive Testing）方式，即题目难度会根据学生的表现不断调整。答对之后，下一题往往会更难；答错之后，系统会转向更容易的题目。
Adaptive testing has two practical consequences. First, it produces a more precise estimate of ability than a fixed paper of the same length, because pupils spend most of their time working near the level at which they are genuinely challenged. Second, it means that a pupil cannot judge performance simply by the number of questions answered, and comparing the number of items completed with a friend is meaningless.
自适应测试有两个实际影响。第一，与同样长度的固定试卷相比，它能更精确地估计能力，因为学生大部分时间都在接近自己真实挑战水平的题目上作答。第二，学生不能仅凭答题数量判断自己考得好不好，与同学比较“做了多少题”没有任何意义。
Pupils should be told clearly that the test is designed to reach questions they cannot answer. Reaching very hard items is a sign of success, not failure, and there is no penalty for guessing in the usual CAT4 administration.
应当明确告诉学生：这个测验本来就会出到他们答不出来的题目。能接触到非常难的题目其实是表现好的信号，而不是失败的信号；在通常的 CAT4 施测中，猜答不倒扣分。
9. Timing, Structure and Levels | 考试时长、结构与级别
The full test takes approximately 2 hours to complete, although the total including instructions and short breaks is often closer to 2 hours and 15 minutes. Schools may administer it in one sitting or split it across two or three sessions, and each of the eight sub-tests has its own short time limit.
完整测试的作答时间约为 2 小时；如果把说明和短暂休息计算在内，通常接近 2 小时 15 分钟。学校可以安排一次性完成，也可以分两到三次进行。八个短测验各自都有单独的限时。
Different levels of CAT4 are used for different year groups, from the lowest level in the early primary years up to Level G for pupils in Year 11 and above. The level a candidate sits is chosen by the school according to age, not by the candidate.
CAT4 针对不同年级设有不同级别，从小学低年级使用的最低级别，到 Year 11 及以上使用的 Level G。考生参加哪个级别由学校按年龄决定，而不是由考生自选。
The tests are strictly timed and the questions get harder, so pacing matters. A sensible strategy is to answer every question in the time available, skip nothing, and spend no more than a few seconds on any single item before moving on.
测试严格限时且题目越来越难，因此答题节奏非常关键。合理的策略是：在限定时间内答完所有题目，不要留空，任何一道题都不要停留超过几秒钟。
10. Reading the CAT4 Report | 如何解读 CAT4 报告
Results are presented as a report showing performance in each module as well as an overall picture of cognitive ability. The most important number is the Standard Age Score, or SAS, which is standardised so that the national average is 100 with a standard deviation of 15.
测试结果会以报告形式呈现，既反映学生在各个模块中的表现，也给出综合认知能力的整体画像。其中最重要的数字是标准年龄分数（SAS），它经过标准化处理，全国平均分为 100，标准差为 15。
SAS = 100 + 15 × z
A SAS of 100 is average for the pupil's age. Roughly speaking, 85 to 115 is the average band, 115 to 130 is above average, and above 130 is well above average and often associated with high academic potential.
SAS 为 100 表示处于同龄人的平均水平。大致来说，85 至 115 属于平均水平，115 至 130 高于平均，130 以上则明显高于平均，通常与较高的学术潜力相关。
Reports also give a stanine from 1 to 9, where 5 is average, and a national percentile rank showing the percentage of pupils in the standardisation sample who scored lower. Parents who want to understand the pattern should look at the profile of SAS scores across the four batteries rather than fixating on the overall figure.
报告还会给出 1 至 9 的九级分（stanine），其中 5 为平均；以及全国百分位排名，表示标准化样本中有多少比例的学生分数低于该生。想真正理解成绩的家长，应重点看四个模块 SAS 的分布组合，而不是只盯着一个总分。
A pupil with a high verbal score and a lower spatial score is a different learner from a pupil with the opposite profile. The profile matters far more than the average of the four batteries.
语言分数高而空间分数较低的学生，与相反画像的学生是完全不同的学习者。四模块的分数结构，比四者的平均分重要得多。
11. Personalised Learning and School Admission | 个性化学习建议与升学用途
CAT4 results are used to provide personalised learning suggestions and educational plans, and to help pupils make the most of their own potential. Teachers use the profile to decide who needs targeted support in reading, who should be stretched in mathematics, and how to group pupils for differentiation.
CAT4 结果可用于提供个性化的学习建议与教育方案，帮助学生充分发挥自身潜力。教师会根据这份画像判断谁需要阅读方面的针对性支持、谁应在数学上获得拔高，以及如何分组实施分层教学。
The same results are also used in admission. CAT4 can serve as one of the entrance examinations for well-known independent schools in the UK, helping schools evaluate a candidate's academic ability and potential alongside English and mathematics papers, interviews and school reports.
同样的成绩也用于招生。CAT4 可以作为英国著名独立中学的入学考试之一，帮助学校在英语、数学笔试、面试和在校报告之外，评估申请者的学术能力与潜力。
Because CAT4 measures reasoning rather than curriculum content, schools interpret it as a measure of potential and of how well a pupil is likely to cope with demanding academic work. A strong CAT4 profile does not guarantee a place, and a weaker profile does not automatically close the door: schools look at the whole application.
由于 CAT4 测的是推理而非课程内容，学校把它视为一种潜力指标，以及学生将来能否适应高强度学术学习的预测依据。CAT4 成绩好并不保证录取，成绩偏低也不等于自动出局，学校看的是完整申请材料。
12. How to Prepare Sensibly | 如何合理备考
CAT4 is not a knowledge test, so there is no content to cram. The most effective preparation is familiarity with question types, steady practice in reasoning, and building the underlying skills of vocabulary, mental arithmetic and visual attention.
CAT4 不是知识型考试，因此没有内容需要死记硬背。最有效的准备是熟悉题型、坚持推理练习，并打好词汇、心算和视觉注意力这些底层能力。
Fifteen to twenty minutes of focused practice, three or four times a week, is usually enough. Practice should always be followed by a review of wrong answers, because the learning lies in understanding why the chosen rule was wrong. Pupils should also practise under timed conditions so that they get used to moving on quickly.
每周三到四次、每次 15 至 20 分钟的高质量练习通常就足够了。每次练习后都要复盘错题，因为真正的学习发生在“为什么我选的规则不成立”这一步。同时应进行限时练习，让学生习惯快速推进。
Common misconceptions are worth clearing up early. CAT4 is not an IQ test in the strict clinical sense; it is not a test of school subjects; it does not have a fixed pass mark; and it cannot be prepared for by memorising answers. It measures how a pupil reasons with words, shapes and numbers, and that capacity develops through reading, puzzles, well-chosen practice and good sleep before test day.
有几个常见误区值得提前澄清：CAT4 不是严格临床意义上的智商测验；它不是学科考试；它没有固定及格线；也不能靠背答案来准备。它测量的是学生用文字、图形和数字进行推理的能力，而这种能力可以通过阅读、益智游戏、有针对性的练习以及考前充足睡眠来逐步提升。
