The Naglieri Nonverbal Ability Test®, or NNAT®

The Naglieri Nonverbal Ability Test®, or NNAT®, is a standardized test developed by Pearson Assessments and used nationwide by school districts to measure the nonverbal general ability of K-12 students.  Most school districts use NNAT® as a criterion for gifted placements and other student credentials.

Poor test preparation and lack of test-wiseness results in test scores that do not accurately reflect the students’ knowledge and aptitude.

These concepts are not part of the regular school curricula, so test preparation is crucial to ensure your children perform their best.  The question types, the strategies, the test format, time management, pacing, and test stamina are developed over a long period and do not happen overnight. Our digital learning platform and practice items simulate the actual NNAT® test.

We structure our NNAT® classes and learning environments to suit your children’s learning needs.

We start with a diagnostic test before the first session so teachers will get an overview of your children’s skills.  Teachers plan instruction and make instructional decisions based on your child's results.  We monitor your children’s progress and constantly adjust our instruction based on your child’s pacing and learning progress.

We will be with you on your journey!

An additional benefit is we guide you through the entire process of getting into the gifted program up to your children’s gifted portfolio preparation.
