The British Ability Scales: Second Edition (BASII) is a reliable measure of cognitive functioning over a wide age range, using ability scales. These are divided into two batteries (Early Years and School Age), and are available separately or together a Full Age Range kit. The assessment enables you to derive a general conceptual ability score (GCA) and three embedded cluster scores by administering only six scales. Where more specific abilities need investigating, other diagnostic scales can be used to provide more details.

• Convenience of one instrument for assessing both abilities and achievement at all ages from pre-school to end of secondary school
• Reliable normative information based on over 1600 individuals drawn from over 200 educational establishments across England, Wales, Scotland and Northern Ireland
• Careful and detailed attention to ethnic-and gender-related fairness
• Flexible instrument enabling accurate assessment of both gifted and developmentally delayed individuals
• Age-related start points and decision points focus on an individualÂ’s ability range, and terminate the scale as soon as sufficient information is gathered to minimise testing times and reduce the risk of fatigue or demoralisation
• Provides the diagnostically important separate assessment of non-verbal reasoning and spatial ability
• Score profiling and diagnostic facilities help support practitioners with a problem solving approach
• Evaluation of predicted against actual achievement in reading, spelling and numeracy provides a defensible method for evaluating ability-achievement discrepancies
• Time-saving Scoring and Reporting Software also available. In addition to presenting profiles and discrepancy scores, it generates two interpretative narrative reports for you to customise or edit; one for parents/teachers and a more technical report for psychologists
