Naglieri Nonverbal Ability Test

The Naglieri Nonverbal Ability Test–Second Edition (NNAT2) is a nonverbal measure of general ability based on a testing method (see Figure 1) supported by nearly a century of research. NNAT2 items assess ability without requiring the student to read, write, or speak. Students must rely on reasoning using geometric designs, not on verbal skills. The NNAT2 has been developed with the goal of providing a means of testing intelligence that is a fair assessment across gender, race, and ethnicity. The NNAT2 is a revision of the Naglieri Nonverbal Ability Test–Multilevel Form, which was a revision of the Matrix Analogies Test – Expanded Form and the Matrix Analogies Test – Short Form, which were used extensively in educational settings.
