Research and practical tools for educators and psychologists
Dr. Jack A. Naglieri is a Senior Research Scientist at the Devereux Center for Resilient Children and Emeritus Professor of Psychology at George Mason University.
For more than 40 years, Dr. Naglieri has focused on improving how we measure thinking and learning in ways that are accurate, practical, and fair. His work has led to the development of several widely used assessments, including the Naglieri Nonverbal Ability Test (NNAT), the Cognitive Assessment System (CAS), the Autism Spectrum Rating Scale (ASRS), the Devereux Student Strengths Assessment (DESSA), the Comprehensive Executive Function Inventory (CEFI), and the Naglieri General Ability Tests.
His work includes research connected to PASS Theory, along with studies focused on identification, executive functioning, social-emotional strengths, and fair access to opportunity. Across all of it, the goal remains the same: give educators and psychologists better tools to understand students and support their potential.

The National Association for Gifted Children (NAGC) will honor Dr. Naglieri with the Distinguished Scholar Award for his contributions to the field of gifted education at its annual conference in November.
Dr. Naglieri regularly presents at national and international conferences, sharing insights on fair assessment, PASS theory, and cognitive evaluation. He offers practical strategies educators can use in their work.

An estimated 1.5 million students likely qualify for gifted programs but haven’t been identified. In this recorded session, Drs. Jack A. Naglieri, Dina Brulles, and Kimberly Lansdowne discuss universal screening using the Naglieri General Ability Tests, which assess verbal, nonverbal, and quantitative skills independently of language.
Key takeaways:
• Benefits of universal screening
• Understanding test accuracy
• Pros and cons of using local vs. national norms
Dr. Jack Naglieri joins Emily Kircher-Morris to discuss IQ, the history and limitations of traditional intelligence testing, and the need for fairer assessment methods. He also explains the PASS theory of intelligence and how it shaped his development of nonverbal assessments and the Cognitive Assessment System (CAS).

The PASS Theory of Intelligence
This e-book explores the origins of the PASS Theory and how it shaped the Cognitive Assessment System (CAS) and its later editions. It highlights the theory’s ongoing impact on modern cognitive assessment.

The Florida Association of School Psychologists (FASP) presented Dr. Jack A. Naglieri with the Legend of School Psychology Award during their 2025 annual conference. This recognition celebrates his lifelong contributions to the field, including his development of cognitive and nonverbal assessments that promote fair and accurate identification for all students.
