The New York City Gifted & Talented Test is a test that is used to identify gifted and talented children for entrance into school accelerated, advanced, gifted and talented programs. The NYC G&T test consists of two parts – a Naglieri Nonverbal Ability Test (NNAT) and the verbal questions from the OLSAT (Otis-Lennon School Ability Test).
The NNAT (Naglieri Nonverbal Ability Test) is a cognitive ability test that is a nonverbal measure of general ability. The NNAT test is a nonverbal test (requiring minimal use of language and instructions) which makes use of abstract shapes and designs, and is therefore a good culturally neutral assessment of general ability.
The OLSAT (Otis-Lennon School Ability Test) is an aptitude test for grades K-12 that measures reasoning and problem solving skills. The OLSAT test contains questions that measure verbal and nonverbal ability, but the NYC G&T only uses the questions from the OLSAT that measure verbal ability (i.e. questions on following directions, aural reasoning and arithmetic reasoning).
