About BAS3

What is BAS3?

The British Ability Scales (BAS) has long been established as a leading standardised battery in the UK for assessing a child’s cognitive ability and educational achievement across a wide age range. Based on significant research and customer feedback, the new edition was launched in November 2011.

The battery of individually administered tests is 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 across the age range 3 years (3:00) to 17 years 11 months (17:11). It also allows a comparison of these aspects with the child’s basic educational progress. Used for a wide range of purposes, the battery can also provide researchers with a valuable research tool.

Comprising 20 shorts tests, each measuring particular types of knowledge, thinking and/or skills, BAS3 remains unique in the range of measurement facilities it offers and the variety of scales it includes. It allows an efficient and reliable assessment in 30-45 minutes, depending on the child.

3rd Edition

The British Ability Scales: Third Edition (BAS3) builds on the strengths of the British Ability Scales: Second Edition (BAS II), while improving usability and attractiveness. To ensure familiarity for existing users of BAS II,BAS3 retains the overall structure and scales featured in its predecessor, yet has been revised and restandardised to ensure the scores obtained are valid, reliable and based on up-to-date comparisons.
