Cognitive Scales (Fluid Intelligence):
– The Leiter-3 emphasizes fluid intelligence, the truest measure of an individuals innate cognitive abilities
-Â This makes more accurate and fair, since IQ is not significantly influenced by the individuals educational, social and family experience
– Sequential Order (SO)
– Form Completion (FC)
– Classification and Analogies (CA)
– Figure Ground (FG)
Attention and Memory Scales:
– Attention and Memory subtests enhance interpretation of the global IQ score, by providing valuable diagnostic indicators regarding the score on the Cognitive portion of the Leiter-3
-Â They also distinguish individuals with ADHD, LD 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 individuals
-Â Attention
– Organization Skills
– Impulse Control
– Activity Level
– Anxiety
– Energy and Feelings
– Mood Regulation
– Sociability
– Sensory Reactivity - Scoring:
– 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
– Percentile and age-equivalent scores are provided
– 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 - Normative Data:
– Normative data includes more than 1,600 individuals, representative of the most current general population, in terms of ethnicity/race, gender and age
– The normative sample is also diverse in terms of parent/self education level and geographical region - Restricted Use:
– Level B-requires that the user has completed graduate-level courses in tests and measurement at a university or has received equivalent documented training
