This session is from the NASP 2022 Annual Convention

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

Learner Objectives

This session will help participants…

  1. understand the relationship between the WJ-IV ECAD and the WPPSI-IV.
  2. articulate the commonalities and differences among the WJ-IV ECAD and the WPPSI-IV, as well as their strengths and weaknesses.
  3. consider the match between assessments and the children's referral concerns and unique characteristics.


The current presentation examines the relationship between young children’s cognitive scores on the WJ IV ECAD and the WPPSI-IV. Preliminary data revealed a strong positive correlation between the WPPSI-IV FSIQ and the WJ IV ECAD GIA. However, the WJ IV ECAD GIA scores were generally higher than WPPSI-IV FSIQ. Practitioners will become better versed with the WJ IV ECAD and participate in a discussion of the instruments' strengths and weaknesses.
