Other populations: Evidence of validityThe Woodcock Johnson has been validated and revised through decades of systematic psychometric test development, and some consider that it has "raised the bar" in terms of cognitive testing (Floyd, Shaver, & McGrew, 2003). The test demonstrates concurrent validity with the Weschler Intelligence Scale for Children-Revised and the Cognitive Abilities Test (Lohman, 2003; Reeve, Hall, & Zakreski, 1979).
