The Naglieri General Ability Tests™ are a suite of assessments designed to measure general intellectual ability in a way that minimizes cultural, linguistic, and academic bias.
About the Naglieri General Ability Tests™
Measure how well students think, rather than what students know.
The Naglieri General Ability Tests: Verbal, Nonverbal & Quantitative, winner of the 2024 Excellence in Equity – Industry Impact Award in the Diversity and Inclusion Solution category, were thoughtfully designed to measure general intellectual ability in a way that minimizes cultural, linguistic, and academic influences.
Test items were carefully designed to allow students to solve problems regardless of the language they speak, significantly reducing the demand for advanced academic knowledge, eliminating the need for verbal responses to the test questions, and greatly reducing cultural influences so the tests measure general ability as fairly as possible.

How Do the Naglieri General Ability Tests™ Work?
Each test takes only 30 minutes or less to complete. The Naglieri General Ability Tests are three separate measures that can be used individually or in any combination. For users requiring multiple measures as part of their identification process, each test can be used as a separate assessment.
With the Naglieri General Ability Tests, local and national norms can be used. For more information on using local and national norms, learn more.
Instructions are presented to the students using animated videos, which eliminates the need for comprehension of verbal directions

“Our campus houses several different Specially Designed Instructional programs, which serve students identified with Dyslexia. A fourth-grade student here who has been a part of both of these programs had been overlooked for the first five years of his educational journey. After administering the Naglieri General Ability Tests in the fourth-grade classes, he scored in the 99th percentile for our entire district on the Nonverbal test. He has since been qualified to receive services from our Gifted and Talented program, something that may not have been possible without the use of the [Naglieri General Ability Tests]. Upon hearing about the results, his parents personally reached out to tell me how many medical professionals from their past had said their child would not succeed in the academic world. This student is breaking down the walls built around him.”
“Through the use of the Naglieri General Ability Tests, we have been able to screen and go on to identify several students who don’t fit the perceived, “gifted mold.” Teachers have been surprised by some of the students that we found. That’s the purpose of this screening!”
