Complete Digital Solution

A ready-made digital package of our leading assessments.

CDS is a powerful combination of digital assessment tools and data insights to give you the whole view of each pupil. The 10 nationally benchmarked assessments provide clear insight into reasoning skills, help you to understand attainment levels in core subject areas and identify barriers to learning. 

Verbal, non-verbal and spatial reasoning skills are measured by Cognitive Abilities Test (CAT4). 

Attainment and progress in core subjects is assessed by Progress Test Series (covering English, maths and science), New Group Reading Test (NGRT) and New Group Spelling Test (NGST). 

Pupil Attitudes to Self and School (PASS), Dyslexia Screener, Dyscalculia Screener, and Kirkland Rowell Surveys can help to identify any barriers to learning.
