Leiter-3 Response Booklet (pkg 20)

The Leiter International Performance Scale - Third Edition (Leiter-3) evaluates nonverbal cognitive, attentional and neuropsychological abilities in typical and atypical children, adolescents and adults (3-75+ years of age). Its engaging, nonverbal format makes it ideal for use of individuals with Autism, Speech/Language Disorders, as well those with English as a second language.

It provides an IQ score, as well as percentile and age-equivalent scores for each subtest. The Leiter-3 provides individual subtest, and numerous composite scores, that measure intelligence and discrete ability areas. These scores identify strengths and weaknesses in individual skills, as well as skill sets.

Growth Scores are provided for all domains, enabling professionals to measure small, but important, cognitive shifts within a skill set, particularly important for children cognitive disabilities. Tracking these shifts allows professionals, educators and parents to see the improvement (growth) across time, irrespective of age-based standard scores.

The Leiter-3 Response Booklet is used for the Attention Sustained and the Nonverbal Stroop subtests. The respondent will mark in the booklet in order for the examiner to score their performance.

If the examiner is not giving subtests on the Attention/Memory battery, they will not need the Response Booklets, only the Record Forms.
