Provides a unique profile of students’ strengths and areas for development.

CAT4 is an assessment of developed abilities in areas known to make a difference to learning and achievement – namely verbal, non-verbal, quantitative and spatial reasoning – and provides you with an accurate analysis of potential student achievement.

Standardised on 25,000 students and verified every year based on analysis of a quarter of a million students, CAT4 provides you with valuable baselining data. It also gives reliable indicators for national tests and examinations, including Key Stage 2 indicators, GCSE and A level, International Baccalaureate and CBSE indicators.
