This session is from the NASP 2021 Annual Convention

  • PMD: 1,9
  • Skill Level: Introduction
  • Session 4: Assessment and Intervention in an RTI Framework

Learner Objectives

This session will help participants…

  1. learn about the types and frequency of administration and scoring errors made by school psychology trainees on the Woodcock Johnson Test of Academic Achievement (WJ-IV ACH).
  2. learn how to improve the academic achievement administration fidelity of trainees/supervisees.
  3. avoid common pitfalls in the administration and scoring of tests of academic achievement.


School psychologists often administer norm-referenced tests of academic achievement. Data gathered from these tests are often used to make high-stakes decisions (e.g., special education eligibility). However, little is known about practitioners’ fidelity with these measures. This poster examines the types and frequency of errors made by 26 school psychology trainees across 64 Woodcock Johnson IV test of achievement protocols. Implications for trainers and practitioners will be discussed.
