The Leiter-3 evaluates nonverbal cognitive, attentional and neuropsychological abilities, and targets "typical" as well as "atypical" children, adolescents, and now adults. Its engaging, 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 provides an IQ score, as well as percentile and age-equivalent scores for each subtest.
Growth Scores are provided for an domains, enabling professionals to measure small, but important, cognitive shifts within a ski II 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.
New Key Features:
• "Block and Frame" format: Creates a more accurate assessment of Autistic individuals.
• Decreased Number of Subtests: Increases overall efficiency and utility of the instrument.
• A Neuropsychological Subtest: (Nonverbal Stroop Test) has been added.
• All New Attention-Divided Subtest: Greater reliability and ease of use.
Leiter-3 Subtests
Cognitive Scales (Fluid Intelligence): The truest measure of an individual's innate cognitive abilities. This makes the Leiter-3 more accurate and fair, since IQ is not significantly influenced by the individual's educational, social and family experience.
• Sequential Order (SO) • Form Completion (FC) • Classification and Analogies (CA)
• Figure Ground (FG) • Matching/Repeated Patterns (M/RP) (optional)
Attention and Memory Scales: Subtests enhance interpretation of the global IQ score, by providing valuable diagnostic indicators regarding the score on the Cognitive portion of the Leiter-3. They also distinguish individuals with ADHD, LO or neuropsychological impairments, from typically-functioning individuals.
• Forward Memory (FM) • Attention Sustained (AS) • Reverse Memory (RM)
• Nonverbal Stroop (NS) • Attention Divided (AD)
Examiner Rating Scale: The Social-Emotional Examiner Rating Scale gathers information about the individual's Attention, Organization Skills, Impulse Control, Activity Level, Anxiety, Energy and Feelings, Mood Regulation, Sociability, and Sensory Reactivity.
