About CAT3

The Cognitive Abilities Test 3 (CAT3) is one of the most widely used tests of reasoning abilities. CAT3 measure three principal forms of reasoning – verbal, non-verbal and numerical – as well as an element of spatial ability. CAT3 can be administered by guidance counsellors, learning support teachers, classroom teachers and psychologists.


pictureThree types of age-related norms are provided for interpretive purposes - standard scores, percentile ranks and stanines. These allow you to compare the cognitive development of a pupil with that of other pupils of the same age. The data from CAT3 can be used to identify individual pupil potential and learning styles and enhance all aspects of the teaching and learning process, from organising classes to predicting future educational attainment.

The CAT3 assesses an individual's ability to reason with and manipulate symbols representing words, quantities and spatial/geometric or figural patterns. Three batteries comprising nine sub-tests were constructed to assess competence in working with each of these types of symbols.



1. CAT3 Verbal Battery Sub-tests = Verbal Classification, Sentence Completion, Verbal Analogies
2. CAT3 Quantitative Battery Sub-tests = Number Analogies, Number Series, Equation Building
3. CAT3 Non-Verbal Battery Sub-tests = Figure Classification, Figure Analogies, Figure Analysis
