Test Reviews

摘要

The Wechsler Nonverbal Scale of Ability (WNV) is a general cognitive ability assessment tool for individuals' aged 4 year 0 months through 21 years 11 months with English language and/or communicative limitations. The test targets a population whose performance on intelligence batteries might be compromised by standard verbal requirements. Specifically, it is intended for use with individuals from diverse backgrounds as well as those who have any type of language limitation due to, but not limited to, the presence of autistic disorders, developmental delays, instructional challenges, environmental challenges (i.e., lack of education), deafness or hard of hearing, and language-based learning disabilities including speech impairment and selective mutism (Wechsler & Naglieri, 2006).
