The British Ability Scales - Third Edition (BAS-3) is a battery of individually administered tests, designed for use by educational and clinical psychologists to assess children or adolescents who have been referred to them for a wide range of reasons, including learning and behavioural difficulties.

It provides a comprehensive and flexible means of assessing different aspects of a child’s current intellectual functioning, and allows a comparison of these aspects with the child’s basic educational progress. Used for a wide range of purposes, the BAS-3 can also provide researchers with a valuable research tool.

Comprising 20 short tests, each measuring particular types of knowledge, thinking and/or skills, the BAS-3 remains unique in the range of measurement facilities it offers and the variety of scales it includes.
