Naglieri Nonverbal Ability Test™ - Individual Administration
Filters
Use the Naglieri Nonverbal Ability Test™ - Individual Administration (NNAT™-Individual) to assess general ability in children and adolescents. With quick and easy administration, it measures ability using diagrams and in a way that does not require verbal skills. Due to the simplicity of directions and the minimal use of language required to solve the items, the NNAT-Individual requires minimal motor requirements and is ideal for use with examinees from culturally and linguistically diverse backgrounds, those with hearing impairments, and those with low or high ability.
- NNAT-Individual is especially appropriate to use for identification of gifted students, especially those from diverse backgrounds.
- Uses progressive matrices, which are fair for all examinees, those with hearing impairments, and those with impaired color vision.
- Ideal for children who do not speak English as their first language—requires no reading, writing, or speaking (examinees just point to the answer they believe is correct).
