A comprehensive, flexible means of assessing various aspects of cognitive functioning from 3 to 18 years.

Significant research and customer feedback have shaped this long-established battery of 20 individual scales, used by psychologists to assess children referred for learning and behavioural difficulties. The scales allow for a comparison of these issues against the child’s educational progress. They can pinpoint gifted and talented pupils as well as underachievers. 

The range of measurement facilities and variety of scales means that BAS3 is trusted by educational, clinical and research psychologists to give valid and reliable scores. The user-friendly scoring and reporting software supports communication with parents, pupils, teachers and senior leaders. 

BAS3 customers receive free access to the automated BAS3 Scoring and Reporting Servicwhen buying the complete set.
