British Ability Scales (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. Record forms and subsequent booklets for the British Ability Scales: Second Edition (BAS II), are still available  - order via the product codes opposite.

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.

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.

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.

BAS3 Scoring and Reporting Service

Scoring and analysing the British Ability Scales: Third Edition (BAS3) can be a time consuming and complex task, however, with the introduction of our new BAS3 Scoring and Reporting Service (SRS), the conversion ofBAS3 scores is made quicker, easier and less prone to errors, with the added benefit of automatic reporting. AllBAS3 customers, whether as an individual or as part of their group service, will receive FREE access to the newBAS3 Scoring and Reporting Service on purchase of the complete set.

The new service is a major element of BAS3, as it replaces the normative tables that could be previously found in the BAS II manuals. For those customers who still have a need or preference to complete scoring by hand, all the tables needed for scoring BAS3 are provided in the SRS in downloadable format. These can be printed off or saved onto a computer.
