General Description of Test:The BAS II (Early Years) – Second Edition is a psychometric test of cognitive abilities, which assists professionals in assessing children’s learning and developmental abilities and disabilities. It is a test battery that assesses children between 2:6 and 3:5 years and 3:6 and 5:11 years. The former age group is assessed, under supervised and controlled administration by the qualified administrator, on six subtests and the latter age group between eight and eleven subtests,depending on age. Each subtest has age-related start points and decision points, which allows for testing on any scale to stop when sufficient information has been collected. Therefore administration, scoring and interpretation time will vary. The BAS II - Early years (Second Edition) is derived from the BAS, BAS-R and DAS and has been devised for the general population, however a General Conceptual Ability score can also be obtained for a child of very low ability with out-of-level administration of the Cognitive Battery in which  a level of the Cognitive Battery normally used with younger children is administered. This instrument has five common core theoretical underpinnings and is compared in terms of its reliability and validity to the DAS and the WPPSI-R. It is scored using complex manual scoring, with most scales scored using a multi-point system. Score interpretations are organised in an hierarchical structure. Both Core and Diagnostic scales can be interpreted individually or Core scales can be clustered to measure Verbal Ability, Pictorial Reasoning Ability and Spatial Ability. These cluster scores together provide for a General Conceptual Ability (GCA) score.
