What is the Naglieri Nonverbal Ability Test (NNAT)?
The NNAT is a group-administered mental ability test that only measures nonverbal abilities. It is similar to, but more in-depth, than the Nonverbal battery of the CogAT. It consists of four sub-tests that require students to complete patterns, sequences, and analogies as well as combine two or more geometric designs. The battery requires no reading and no outside fund of knowledge. The NNAT is administered in one 45-minute session. The resulting score is reported as a national percentile ranking to parents in the Mental Ability section on the Data Collection Instrument (DCI). The 96th percentile is the qualifying score. The NNAT is only administered once every two years.
