When schools identify students for gifted programs, they commonly use two tests: the Naglieri Nonverbal Ability Test (NNAT) and the Cognitive Abilities Test (CogAT). It’s important to understand that the decision on which test your child takes is made by your school or district, parents do not select the test. This article helps parents understand each test’s differences and how to support their child’s preparation effectively.
NNAT vs CogAT Comparison: What’s Being Tested?
CogAT (Cognitive Abilities Test):
Measures verbal, quantitative, and nonverbal reasoning. Children answer questions about language, math patterns, and pictures. This comprehensive test gives educators a detailed profile of a child’s learning strengths for personalized enrichment.
NNAT (Naglieri Nonverbal Ability Test):
It is fully nonverbal and picture-based, focusing on pattern recognition, analogies, and spatial reasoning. It minimizes language dependency, which benefits children with limited English proficiency or in multicultural classrooms. The NNAT is typically shorter and tests only visual-spatial skills.
CogAT vs NNAT Differences: Structure and Student Experience
| Feature | CogAT | NNAT |
| Question Types | Verbal, Quantitative, Nonverbal | Nonverbal only |
| Test Length | Longer, multiple batteries | Shorter, fewer questions |

Supporting Your Child’s Preparation
Since your child’s school decides the assessment, parents have one crucial role: to support test preparation for whichever test their child will take. Here’s how parents can help:
- Familiarize your child with the test format and question types through grade-level practice questions.
- Encourage regular, low-stress practice to build cognitive skills and reduce test anxiety.
- Use realistic practice materials to give your child confidence and help them become comfortable with timing and question styles.
- Celebrate effort and improvement, fostering a positive attitude toward testing.
