(L3 -1 LEITER) Retains the best of the widely used Leiter-R subtests and includes a number of new measures.

•Uses a refined block-and-frame format and plus foam manipulatives for easier manipulation by all examinees.

• Features increased overall efficiency and utility; Leiter-R subtests were combined and items with similar difficulty levels were removed, reducing the number of subtests from 20 to 10.

•A neuropsychological subtest (Nonverbal Stroop Test) has been added; the Attention-Divided subtest is all new and features greater reliability and ease of use.

Features and benefits
• Evaluates nonverbal cognitive, attentional, and neuropsychological abilities, and targets “typical” as well as “atypical” children, adolescents, and now adults.

• 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.

• Provides an IQ score, as well as percentile and age-equivalent scores for each subtest. Growth scores are provided for all domains.

• Easy, game-like administration holds examinees’ interest throughout the test.

Test structure
• Provides individual subtest scores and numerous composite scores that measure intelligence and discrete ability areas. These scores identify strengths and weaknesses in individual skills and skill sets.
• Includes Cognitive scales that, unlike those in other IQ tests, emphasize 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.

• Attention and Memory subtests enhance interpretation of the global IQ score by providing valuable diagnostic indicators regarding the Cognitive scores. They also distinguish individuals with ADHD, LD, or neuropsychological impairments from typically-functioning individuals.

• 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.

Technical information
• Psychometric studies show the Leiter-3 to have exceptional fairness for all cultural and ethnic backgrounds.

•Normative sample included more than 1,600 individuals representative of the most current general population in terms of ethnicity/race, gender and age and diverse in terms of parent/self-education level and geographical region.

•Features enhanced data on difficult-to-assess clinical groups, including ADHD, autism, severe cognitive delay, ESL, gifted/talented, severe hearing impairment, LD, severe motor delay, and severe speech/language impairment.
