Naglieri Nonverbal Ability Test

The Naglieri Nonverbal Ability Test (NNAT) is a nonverbal measure of general ability designed by Jack A. Naglieri and published by Pearson Education. [1] The Naglieri Nonverbal Ability Test - Individual Form was first published in 1998. Two versions were published in 2007 and 2008, respectively. This includes the group administered Naglieri Nonverbal Ability Test - Second Edition and the Naglieri Nonverbal Ability Test - Online version. The most current version is NNAT3.[1] Like all nonverbal ability tests, the NNAT is intended to assess cognitive ability independently of linguistic and cultural background.[1]

Present use

These tests may be administered to K–12 school children on an individual or group basis as a means to identify potentially gifted children for placement in accelerated programs.[1] It is also used for admission by several high IQ societies; for instance Intertel accepts scores at or above the 99th percentile.[2][3]

NNAT and the media

Beginning in the 2012-13 school year, the Naglieri Nonverbal Ability Test- 2nd Edition (NNAT-2) replaced the Bracken School Readiness Assessment (BSRA) in New York City.[4] The decision sparked some controversy because some parents considered the test too difficult.[5]

In New York City, the NNAT-2 makes up 50% of the gifted and talented exam, the other 50% is the Otis–Lennon School Ability Test (OLSAT).

Criticism

The NNAT has been found by one study to show excessive score variability, with within-grade standard deviations reaching as high as 20 points. This has the effect of both overrepresenting and underrepresenting index scores - that is, more students received very high or very low scores than expected. Lohman et al. found that 3.4 times as many students scored in the 130+ range on the NNAT as expected.[6]
