Why was Block Design selected as the first subtest for WAIS–IV UK?
Block Design was chosen as the first subtest because it is an engaging task that gives the examiner more opportunity to establish rapport. This is consistent with a recent revision of another Wechsler product, the WISC–IV, where Block Design as the initial subtest has been well-received by examiners. When testing examinees with motor impairment, examiners may decide to begin with a different subtest in the interest of rapport.
