  • PMD: 1
  • Skill Level: Intermediate
  • Session 6: Recent Developments in Assessment and Research

Learner Objectives

This session will help participants…

  1. critically assess a commonly used cognitive assessment.
  2. learn more about statistically defensible assessment interpretation.
  3. discuss pressing critiques of currently accepted intelligence theory and SLD identification.


How well does the factor structure Woodcock-Johnson IV Test of Cognitive Abilities hold over time? How does factor structure influence real world interpretation practices during psychoeducational evaluations? This session presents the results of independent exploratory and confirmatory factor analyses over time of the WJ-IV COG in a school referral population. Practitioners will learn how to critically evaluate the cognitive assessments and theory they use and translate the results into clinical practice.
