What is the Naglieri Nonverbal Ability Test?

The Naglieri Nonverbal Ability Test (NNAT) is a standardized assessment designed to measure general intellectual ability without relying on language skills. It is particularly useful for evaluating children from diverse linguistic and cultural backgrounds, as it minimizes the influence of language comprehension and verbal reasoning on the test results.

Key Features of the NNAT:

• Nonverbal Format: The test uses geometric shapes and patterns, asking test-takers to recognize sequences, identify relationships between shapes, and solve problems without relying on written or spoken language.

• Age Range: The NNAT is typically administered to children in kindergarten through 12th grade.

• Purpose: The test is used to identify gifted and talented students, as well as to assess cognitive abilities in children who may struggle with traditional, language-based tests.

• Scoring: The results are presented as a Nonverbal Ability Index (NAI), which is a standardized score that compares the individual’s performance to that of their peers.

There are different versions of the test, such as the NNAT2 and NNAT3, which have been updated to refine the assessment process and provide more accurate evaluations.
