Chosen by schools for its proven accuracy in delivering insights that curriculum tests can’t, CAT4 is the UK’s most widely used test of reasoning abilities for children aged 6–17+ years.

Measuring the four main types of ability known to make a difference to learning and achievement, CAT4 provides an independent perspective on potential pupil achievement, with reliable information for each child that will help identify where to provide extra support or set more challenging targets.

CAT4 can also be used to establish a baseline and uncover hidden abilities at transition to secondary school. Watch our short video to see how.

How can CAT4 make a difference to you?

CAT4 questions answered

What does CAT4 do?

Provides a rounded profile of pupil ability so you can target support, provide the right level of challenge and make informed decisions about pupils’ progress. It provides a unique profile of strengths and weaknesses across four batteries:

Verbal Reasoning – the ability to express ideas and reason through words is essential to subjects with a high language content, and the most obvious skill picked up by traditional assessment.

Non-verbal Reasoning – problem-solving using pictures and diagrams; skills which are important in a wide range of school subjects, including maths and science-based subjects.

Spatial Reasoning – the capacity to think and draw conclusions in three dimensions, needed for many STEM subjects, but not easily measured by other datasets.

Quantitative Reasoning – the ability to use numerical skills to solve problems, applicable well beyond mathematics.

Why use CAT4?

It’s statistically reliable. CAT4 was standardised on 25,000 pupils and it’s verified every year based on analysis from a quarter of a million pupils.

What does CAT4 tell you?

The true potential of pupils, flagging where hidden factors are affecting performance. A range of easy-to-follow individual and group reports provide a more complete picture than curriculum tests can provide by themselves. They’re benchmarked against national performance and include KS2, GCSE and A-level indicators.

How do I use CAT4?

CAT4 can be taken online or on paper at any point in the academic year. And because the data is robust it supports feedback and planning discussions with senior leaders, pupils and parents.

CAT4 Young Learners (a shorter, paper-based version of CAT4 adapted for young children) is available for children aged 6 - 8 years.

CAT4 is available for children aged 7:06 – 17+ years and comes in seven different levels of difficulty. Each comprises three tests of 45 minutes each; 2 hours 15 minutes in total.

Who uses CAT4?

Over three quarters of a million pupils take CAT4 each year.
