Nonverbal intelligence and cognitive abilities test, updated and re-designed for expanded age groups and specific disabilities, reflecting current population demographics.
The Leiter International Performance Scale Third Edition (Leiter-3) evaluates nonverbal cognitive, attentional and neuropsychological abilities, and targets "typical" as well as "atypical" children, adolescents, and now adults. Its engaging, completely nonverbal format makes it ideal for use with individuals with Autism and Speech/Language Disorders, as well as those who do not speak English. It is essential to use non-verbal cognitive testing with these groups, as deficits in verbal abilities masks cognitive assets and deficits, which need to be targeted in educational treatment plans. The Leiter-3 maintains an easy, game-like administration throughout the test, which holds interest for a wide range of ages and clinical groups.
The Leiter-3 has retained the best of the widely-used Leiter-R subtests, and includes a number of new measures. It now uses a refined block-and-frame format, plus foam manipulatives, for easier manipulation by all subjects. It provides an IQ score, as well as percentile and age-equivalent scores for each subtest.
Overall efficiency and utility of the Leiter-3 has been increased by combining Leiter-R subtests, and removing items with similar difficulty levels, based on Leiter-R data. Through this process, the number of subtests has been reduced from 20 to 10. The streamlined Leiter-3 provides improved assessment of Fluid Reasoning and Attention/Memory.
