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 2004. 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]

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).[2]

The decision sparked some degree of controversy[3] The NNAT-2 is considered significantly harder than the Bracken School Readiness Assessment (BSRA) which it replaced.

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.[4]

gollark: Is the Soviet national anthem thing working okay?
gollark: I've never heard *that* (about the not being allowed external logs thing), but it sounds rather evil of them.
gollark: Invites-for-access-control are kind of terrible to be honest.
gollark: I wonder how that works.
