The Cognitive Abilities Test: Fourth Edition (CAT4) provides a robust, standardised measure of cognitive reasoning ability, without reference to curriculum-based material and regardless of previous achievements or first language.

The information on this page will help you to understand how the tests can be used and how to interpret the data that they generate.

How to use CAT4

CAT4 is available in paper or digital formats and can be administered individually or in a group setting to produce robust and rigorous results from age 6.6 to 17+ years.

It is important to select the correct level for the students being tested, and to follow the administration guidance to ensure an accurate result.
