Clinicians owe a debt of gratitude to McCaffrey and his team for developing not just one (McCaffrey et al., 2000) but now a second set of tables providing an extensive compilation of test–retest data for tests commonly used in neuropsychological assessment. The newest Practitioner's Guide presents the retest findings for all four versions of the adult Wechsler Intelligence Scale [Wechsler-Bellevue, the original Wechsler Adult Intelligence Scale (WAIS), and its variants: WAIS–R, WAIS–III, WAIS–RNI], plus the Wechsler Intelligence Scale for Children (WISC) with its variants (WISC–R, WISC–III) and the Wechsler Preschool and Primary Scale of Intelligence. For each of Wechsler's batteries this guide provides retest data for the scores in common use (e.g., IQ, VIQ, PIQ, each individual test, and WAIS–III index scores). In addition retest findings are given for the North American Reading Test, Raven's Progressive Matrices, Shipley-Hartford Institute of Living Scale, and for 13 Stanford-Binet studies (form L-M, judging from study dates; all but five are IQ scores).
