Entrance Test

The Cognitive Abilities Test (CAT4) is a suite of diagnostic assessments of developed ability and likely academic potential. By measuring a student’s ability to reason with different types of material, CAT4 allows you to assess the way a student thinks and how they will learn best, and in turn, enables you to adapt teaching accordingly.

The test is not based on any curriculum or dependent on prior learning, offering a fair assessment of ability regardless of a student’s prior schooling. Because three of the four batteries are not reliant on knowledge of the English language, the test is ideal for assessing EAL students.

CAT4 provides a unique profile of students’ strengths and weaknesses across four batteries:
a) Verbal: The ability to express ideas and reason through words is essential to subjects with high language content, and the most obvious skill picked up by traditional assessment.
b) Non-Verbal: Problem-solving using pictures and diagrams; skills which are important in a wide range of school subjects, including maths and science-based subjects.
c) Quantitative: The capacity to think and draw conclusions in three dimensions, needed for many STEM subjects, but not easily measured by other datasets.
d) Spatial Reasoning: The ability to use numerical skills to solve problems, applicable well beyond mathematics.

The data can be used to identify specific groups of students including special educational needs and gifted and talented. Students with a high spatial score are likely to be strong in STEM subjects.

The entrance test fee is £50.
