NNAT® Test (Naglieri Nonverbal Ability Test)

The Naglieri Nonverbal Ability Test® (NNAT® Test or the NNAT®-2 Test) are nonverbal tests that  rely on shapes and figures rather than pictures or words.  These tests assess a child’s thinking and reasoning abilities, as opposed to what he or she has learned in school. Since the NNAT-2 test is nonverbal, it can evaluate the cognitive abilities of a child regardless of cultural background.

There are 4 types of questions on the NNAT-2 test:

  • Pattern completion
  • Reasoning by analogy
  • Serial reasoning
  • Spatial visualization

Even though the NNAT-2 test is assigned by grade level, it is scored based on a child’s age.  Children are compared to other children within 3 months of their own age. Whether your child is taking the NNAT® test or NNAT®2 test, the questions are formatted in the same way.

  • Children entering or in kindergarten will take the Level A exam, which has Pattern Completion and Reasoning by Analogy questions.
  • Children in first grade will take the Level B exam, which has Pattern Completion, Reasoning by Analogy and Serial Reasoning questions.
  • Children in second grade will take the Level C exam, which has Reasoning by Analogy, Pattern Completion, Serial Reasoning, and Spatial Visualization questions.
  • Children in third and fourth grade will take the Level D exam, which has Spatial Visualization questions, Reasoning by Analogy, Serial Reasoning, and Pattern Completion questions.
  • Children in fifth and sixth grade will take the Level E exam, which has Spatial Visualization questions, Serial Reasoning, Reasoning by Analogy, and Pattern Completion questions.
  • Children in seventh through ninth grade will take the Level F exam, which has Spatial Visualization questions, Reasoning by Analogy, Serial Reasoning and Pattern Completion questions.
  • Children in tenth through twelfth grade will take the Level G exam, which has Spatial Visualization questions, Serial Reasoning and Reasoning by Analogy questions.

The NNAT-2 is used for screening for gifted and talented and GATE programs across the US.  A few of the larger school districts use the NNAT-2 and NNAT-3 as part of their admission requirements:

  • Houston ISD for Vanguard Program
  • Virginia Beach, Virginia
  • New York City Gifted and Talented Program
