Distinguishing between the Naglieri Nonverbal Ability Tests & the Naglieri General Ability Tests

Thank you for visiting our website and for your interest in the Naglieri General Ability Tests. Like the Naglieri Nonverbal Ability Tests (NNAT), these tests are used for identifying gifted students. However, several important distinctions exist. The Naglieri General Ability Tests incorporate innovative approaches to test construction, allowing us to identify students with high intellectual ability in a fair manner. To achieve that goal, we created new tests that can be solved regardless of the language a student knows and with test questions that require only a small amount of knowledge.


The Naglieri General Ability Tests measure general ability using verbal, quantitative, and nonverbal test questions, whereas the NNAT measures general ability using only a nonverbal format. It is also important to note that the Naglieri General Ability Tests include verbal and quantitative components for a more diverse approach to measuring general ability. Additionally, the Naglieri General Ability Tests offer nonverbal versions with all new items.

Addressing Barriers in Gifted Identification

Researchers have estimated that over 1,250,000 students in K–12 public schools may have qualified for gifted programs but were not identified. This issue could be addressed by using ability tests that are designed and validated to be fair for every student.

Measuring Thinking, Not Knowing

In this video, Dr. Jack A. Naglieri, Dr. Dina M.

What do students think about these tests?

Unlike traditional assessments, the Naglieri General Ability Tests are designed to be more engaging and accessible for all students. The test format helps students focus on thinking rather than memorization, reducing stress and improving performance.
